Some common gender myths and their rebuttals

It seems like the same discussions come up around Reddit a lot, so I figured I'd gather up some common topics, and their rebuttals.
Many of these arguments can be expanded with more points and sources but I'm trying to keep this as compact and to the point as possible.

Myth 1: "Sexism against men is never institutional or systematic"

Many forms of sexism and discrimination against men are explicitly institutionalized or systemic in society.
Examples include police violence, court biases, incarceration, child custody discrimination, military service, educational biases, health research and spending, insurance, housing discrimination, reproductive rights, bodily autonomy rights, and many others.
The widespread ignorance and denialism around these issues can itself be interpreted as a form of systemic discrimination against men as well.
Note that some of these are institutional because they boil down to statutory legal rights which exist in the realm of government policy and administration. And the government is obviously an institution.

Myth 2: "Most politicians and CEOs are men, and this has led to a society that privileges men and disenfranchises women"

The fact that many positions of formal power are occupied by men does not translate into measurable privileges for the average man.
The assumption this is based on is the idea that men have an in-group bias and prefer other men over women.
Which is an idea that has been debunked over and over again in the academic literature. The gender bias among men is almost zero, and sometimes manifests as an out-group bias sightly in favor of women, not other men.
In-group bisses do exist among women though. In fact some research has found evidence for very strong gender biases among women. Including when it comes to educators, bosses, and hiring managers. Women in formal positions of power do actually seem to prefer other women over men, in much the same way that men are accused of behaving. So maybe this is just projection: people who themselves have gender biases assume that everyone else does as well.

Myth 3: "Women were uniquely oppressed in history compared to men"

Much like today, sexism in history was often two sides of the same coin. If it was unfair that women had to stay home and take care of their children then it was also unfair that men had to work long hours outside the comfort of their homes. Many people try to equate sexism to the history of racism, as if men were unilaterally oppressing women for their own benefit. And that's simply not an accurate view of history (nor is it a very healthy belief to have).
Gender norms were often unfair to women. But for most of history, women could own property, get divorced (where they usually took most of their husband's money), run businesses, and even be heads of state. Many large empires were ran by women, for example.
The reality of the situation though is that pregnancy (and breastfeeding) often dictated the need for women to have men supporting them. Birth control and baby formula didn't exist. So your options were basically abstinence, or marriage. Which was the same choice that men also had.

"What about voting rights?"
Voting rights were historically tied to military service and the draft. It was never something that men got "for free" just for being men.
In England, most men couldn't vote until 1918, and that was only because they instituted a draft for all men during WWI.
Women aged 30 and older were also given the right to vote in 1918, and this came without the same obligation to serve in the military that men had. Women over 21 were given voting rights just 10 years later in 1928, which was the same age that men could vote. And that temporary age difference had a practical purposes: so many men died in WW1 that there was a need to even out the gender ratio.
So men have been allowed to vote for a whopping 10 years longer than women, at most. And that was only because of the mass, involuntary slaughter that they experienced around the world during WW1.
Other obligations that men had were paying taxes, attending caucuses, and signing up for bucket bridges to fight fires.
It took a few decades in some parts of the world for people to decide that it was fair for women to be able to vote without giving anything back to the state, but I think it's important to understand the context here. It wasn't misogyny or oppression but political theory. Specifically the question of whether or not it was fair to give women voting rights without equivalent responsibilities that were required from men (something known as a moral hazard, and that can be contextualized as "female privilege also sometimes harming women").

Myth 4: "Domestic violence and sexual assault are primarily women's issues"

Domestic violence and sexual assault affects everyone, and at nearly identical rates between men and women.
In the US, roughly 37.3% of women have been victims of domestic violence, stalking, sexual harassment, and sexual abuse. Including 1.4 million women who experience sexual assault annually.
For men that same figure is 30.9%. Including 1.7 million men who experience sexually assault annually (defined as "made to penetrate"). The vast majority of these men are also victimized by women, not by "other men" (which is another myth).
This pattern is similar across the world, including in poor and underdeveloped nations (see here for a collection of studies), and is consistent with a wide range of research demonstrating "gender parity" between men and women for this topic.

http://webshare.law.ucla.edu/Faculty/bibs/stemple/Stemple-SexualVictimizationPerpetratedFinal.pdf
https://1in6.org
It's also not true that there's a significant difference in severity between male and female victims. Around 66% of intimate partner homicides do have women as victims (which is hardly a staggering majority), but when you include intimate partner related suicide deaths (including assisted suicides), a greater number of men are killed because of domestic violence than women. These statistic also ignore the fact that lesbian relationships are more violent than heterosexual and gay male relationships. Which inflates these numbers and doesn't necessarily back up the idea that women are being uniquely victimized by men.
We should obviously work to fight against abuse in any form, but our current, gendered approach to this doesn't seem to be helping very much. It is also commonly used as an excuse for misandry. Many people who discuss abuse against women do not actually care about female victims. All they care about is advancing a culture of hatred and sexism against men.

"But women are afraid to walk down dark alleyways at night!"
As they should. And as do men. Most violent crime targets men. And fear is subjective. This is hardly evidence of some kind of unique oppression against women (at least one that doesn't also affect men), and it ignores the fact that men are usually afraid of finding themselves in those same situations as well.
Men are stronger and more capable of defending themselves so I wouldn't blame someone for having gendered views or assumptions here. But let's try not to minimize male victimization or blame it on things like "male oppression".

Myth 5: "False allegations are extremely rare"

Multiple studies have found alarmingly high rates of false allegations in society.
As many as 1 in 7 men have been falsely accused at some point in their life, and they often have to live with those allegations even after proving their innocence.
In addition, around 1 in 20 women have also been falsely accused at some point during their life.
False allegations are particularly common when it comes to child custody and divorce, where well over half of all allegations have been estimated to be false. There is also a common racial element that targets minority men. Especially in history during the era of lynchings in the US.

Myth 6: "Men commit suicide more often than women, but women still attempt suicide more often than men"

This idea has its origins with faulty hospital reporting which lumps suicide attempts in with self-harm (which is something that's more common among women). Women are also more likely to report their suicide attempts than men. And even if this statistic were accurate, it ignores the obvious fact that a suicide survivor can attempt again, thus artificially inflating this statistic.
The fact is, most suicid deaths are men, and most evidence points to there being more unique attempts by men. Any evidence that men are "better" at it than women has been interpreted as evidence for greater motivation of success, due to the very same factors that lead them to attempt suicide to begin with. Not as evidence that women are somehow attempting suicide at rates similar to men in the background.

Myth 7: "Men make more money because of their gender, and this is evidence of male privilege"

Existing gender norms encourage men to earn money in order to meet the financial demands that are placed on them by women.
This causes them to work harder and sacrifice more for their careers than women. Which they do in part because their income is tied to how successful they are with women, and whether or not they qualify as "marriage material".
The wage gap is therefore an example of a gender norm that harms men just as much as it does women.
92% of workplace deaths are men. Men work on average an extra 4 to 10 hours a week (depending on your source) than women. They start working at a younger age (often skirting child labor laws). They retire later (which is also during their peak earning years). And they die sooner than women. Men have worse health outcomes than women and that's largely because of the pressures that society puts on them to be successful and earn money to spend on women.
This is the other side of the wage gap that is equally as important, and that is equally as harmfully to men as it is to women. And it's really just the tip of the iceberg.
In many ways the wage gap is just a reflection of the financial exploitation of men in society. Which is facilitated by things like hypergamy and unfair marriage and divorce practices.

Myth 8: "Men don't go to the doctor because of toxic masculinity"

The main reason that men sometimes don't seek help is a lack of time to see a doctor.
Men work longer hours than women at jobs that are less flexible, and more stressful, than jobs that women usually work at. Men overall engage in an extra hour of paid and unpaid labor per day compared to women, and an extra 45 minutes commuting to jobs that are further away. Meaning men on average have quite a bit less free time to go see a doctor than women do.
This is also something that changes during retirement: retired men are just as likely to go to the doctor as retired women.
https://bmjopen.bmj.com/content/3/8/e003320
A general lack of help and support, especially financial support, for men who need medical help also contributes to this. There is a myth that men are better taken care of than women which has resulted in gendered policies that help women, but exclude men. Even though it's men who often need that help more.

Myth 9: "Men don't speak up about sexism as much as women, so it's obviously not as big of an issue"

This is because people are less likely to care or listen to them. In part because many men who do speak up are silenced and accused of being misogynistic. A situation known as testimonial injustice or epistemic oppression.
Men are told to keep quiet and many end up internalizing the idea that only women can be discriminated against, since this is what society tells us to believe. Instead, men often adopt different terminology when they discuss gender issues. Like referring to differences in treatment between men and women as "double standards" instead of sexism or discrimination.

Myth 10: "Most men's issues are caused by men themselves"

Most men's issues are caused by gender norms and those gender norms are enforced by women just as much as they are by men.
Men's issues are often just one side of the coin, and usually reflect disadvantages that women face as well.
One of the biggest gender norms in society is hypergamy, or the tendency for women to try to marry up, and for men to marry down. And this gender norm is mostly enforced by women, not by men.
Two other gender norm that are enforced by women is the providership gender norm, and the childcare gender norm. Which also causes women to perform more unpaid work and earn less money than men in the labor market.
A fourth gender norm that is enforced by women more than men is the "boys don't cry bias". Which is mainly instilled in young boys by their mothers and by female school teachers. In fact, fathers and male school teachers actually fight against this gender norm.

Myth 11: "Toxic masculinity is harming men and their mental health"

The concept of toxic masculinity has never been empirically tested, and some research questions the validity of it in the context of psychology and mental health.
Even if you do think it is valid though, it is still commonly used in a way that is sexist and hateful torwards men.
In recent years it has become associated with female supremacy, feminist hostility towards men, and misandry in general. And as a result, the vast majority of men find the term to be sexist and offensive.
Men who identify with traditional masculine values have greater self-esteem, better mental health, better relationships with women, and are usually better educated than men who are opposed to masculinity or who accept feminist views about the patriarchy and toxic masculinity.
The key to better mental health for men might therefore be an embracement of masculinity, not a shunning of it. Instead of trying to redefine masculinity, we should work to understand it better, and offer men better services based on an honest acknowledgement that men's and women's mental health might require different approaches.
Men are not "defective women", and treating men's mental health in that context does not seem to be working very well.

Myth 12: "Most men's activists just hate women or are opposed to feminism. They don't really care about men."

This rhetoric is normally used to silence the voices of men (and women) who support men's rights and prevent them from expressing themselves. Which makes it another example of testimonial injustice or epistemic oppression.
The fact is that many people do care about men's issues, and that's why they become MRAs. Feminism does get discussed in the men's movement, but there are a couple reasons for that:
  1. Many feminists, "radical" or otherwise, have advocated against men and have even pushed for public policy in ways that are harmful to men or discriminates against men. Feminists themselves tend to not fight against this, meaning it's often up to MRAs to address it.
  2. Many MRAs are themselves current or ex-feminists who were ostracized for daring to take the feminist rhetoric about "also caring about men" a little too seriously.
Warren Farrell is a great example of this. He used to be on the board of directors for NOW, the world's largest feminist organization.
And then he said that we need to work on child custody equality and reproductive rights for men. Topics that he assumed should fall under the umbrella of feminism since they are issues pertaining to gender equality. Instead of agreeing with him though, he ended up being excommunicated from the feminist movement. And now he's often regarded as the "father of the modern men's movement" for carrying on his advocacy outside of feminism.
The problem that many MRAs have with feminism is that it usually stops half way when advocating for gender equality.
So sometimes what MRAs are doing is just taking it the rest of the way towards actual gender equality. Our frustration with feminists comes from the fact that they refuse to see this as valid (or do it themselves to begin with).

Myth 13: "Men don't receive custody of their children because they're bad fathers and don't bother requesting custody"

Academic research simply does not back this up. The only study that ever found something like this was discovered to be purposefully fraudulent, although that hasn't stopped people from trying to repeat this. The fact is that men are widely discriminated against on numerous different fronts when it comes to child custody and other areas involving family court law.
Note also how hateful this rhetoric is. This is the kind of stuff that you find repeated by feminists, and it simply doesn't treat this topic in a fair and honest manner. Fathers love their children and many fight tooth and nail just to get a few hours a week to spend with them. The system is broken and it represents a grave social injustice that is deeply unfair to fathers and their children.

Myth 14: "Most child abusers are men"

A majority of child abuse is actually committed by women, and especially by mothers. This is even more true when you include emotional abuse and neglect instead of just physical abuse.
By some metrics, the biological father is the safest person for a child to be with. This is because when men do abuse children, it often happens while under the custody of the mother. Who is sometimes complicit in the abuse or even encourages it.
Close to half of child abductors and traffickers are also women, not men. And many of their victims are boys. Boys face sexual abuse and are also used for forced labor and organ harvesting. They are less likely to survive or escape, are less likely to be reported on or identified, and they suffer from higher rates of abuse than girls who are trafficked.
And yet very little attention is given to this. Missing boys, and especially missing minority boys, are often ignored by society and the media. To the point that people often assume that most of the victims are girls. Something which is known as the missing white woman syndrome (although in Canada there is a lot of attention given to missing indigenous women, even though 71% of missing indigenous people are men and boys).
Note that I'm not saying these things to attack women, imply that they shouldn't receive custody, or to downplay the plight of girls. Which is a lot more than you can say about people who try to paint men as the villains in this picture. We should however be fair about what the facts are, and give male victimization, including victimization by women, the attention that it deserves.

Fair is fair and equal is equal. Gender equality will never be fixed if we refuse to look at both sides of the coin. We need to be honest about what the problems are, and stop ignoring them when they involve men, fathers, and boys.

Children and adults should avoid consuming animal products to reduce risk for chronic disease: NO

Frédéric Leroy, Neal D Barnard
The American Journal of Clinical Nutrition, nqaa236, https://doi.org/10.1093/ajcn/nqaa236
Published: 05 September 2020

ABSTRACT

Excessive attention to the animal versus plant binary food choice reflects society's moral views on eating right. To claim that avoidance of animal products is required to prevent chronic disease is not supported by evidence, makes little sense from an evolutionary perspective, and distracts policy makers from common-sense approaches to achieve adequate nutrition. Animal products provide highly bioavailable nutrients, some of which are not easily obtained from plants, and can play a key role in meeting the nutritional challenges of populations in both high- and low-income countries. This role goes beyond the need for protein and relates to vitamins, minerals, and numerous often-overlooked nutrients, such as long-chain fatty acids, taurine, and choline. Restrictive dietary prescriptions that exclude animal products complicate the quest for optimal nutrition by undermining dietary diversity and flexibility, and by introducing a dependency on fortification and supplementation. Thus, a vegan diet may put the general population at increased risk of poor nutrition, a problem of particular concern for those with special nutritional requirements.

Main Argument (Leroy)

An evolutionary perspective argues against the need to eliminate animal-source foods

As with all animals, human nutritional requirements have been influenced by dietary composition throughout the evolution of our species (1). Reliance on substantial amounts of animal foods from both terrestrial and aquatic origin (marrow, organs, fat, meat, eggs, fish, and/or seafood) is characteristic of the human diet throughout the Pleistocene and more recent hunter-gatherers, which can—to some degree—serve as models for ancestral behavior (2). Depending on which resources are available within each habitat, the share of animal products in such diets (as a proportion of total energy) usually exceeds what is now consumed in the West, with only occasional incidences of chronic “diseases of modernity” (3). These evolutionary relationships have influenced our reproductive, digestive, and metabolic functions, fulfilling the nutritional requirements for the development of a large brain (1, 2). The consumption of (fermented) milk exerted an additional evolutionary influence since the Neolithic in populations with access to livestock. The relatively short time frame during which lactase persistence developed indicates that dairy provided strong nutritional benefits for crop-based and malnourished populations in need of protein and micronutrients. The fact that animal products have provided indispensable nutrition for at least 1.5 million years (1) is hard to reconcile with arguments for their exclusion from current diets (2, 4).

The intake of animal foods cannot be causally linked to the incidence of chronic diseases

Available epidemiological studies predominantly point toward neutral or protective associations for such animal foods as dairy, fish, and poultry (5–8). In contrast, various (but not all) observational studies have shown weak relative-risk estimates for high red- or processed-meat intake (i.e., amounts far exceeding 1 serving/d). However, the latter diminish with studies having a lower risk of bias (9) or when cross-cultural assessment is performed (4). In less-Westernized settings, associations tend to disappear or even invert, indicating strong effect modification and confounding by baseline nutritional status and healthy user bias. Regarding the latter, lifestyle characteristics of low versus high consumers of red and processed meats indicate likely bias among these associations in Western countries. Vegetarians differ from nonvegetarians with respect not only to the amount of meat consumed, but also to smoking, physical activity, alcohol consumption, and processed-food intake. Overall, evidence for a causal connection between red- or processed-meat intake and chronic diseases or mortality is inconsistent and inconclusive. Indeed, there is at most “low” to “very low” certainty evidence that higher intakes of red and processed meats result in small reductions in cancer mortality and incidence (10) or cardiometabolic outcomes and all-cause mortality (11). Similarly, there is little evidence that severe restriction of animal foods beyond a well-formulated omnivorous diet would reduce the prevalence of overweight and obesity (12).
Animal and human intervention studies of causal mechanisms typically address only short-term and intermediate surrogate outcomes, whereas markers of oxidative and inflammatory stress or cardiovascular risk fail to indicate harm (4, 13). While a modest increase in LDL cholesterol may occur, animal foods decrease apoB-to-apoA1 ratio, a strong marker of small, dense LDL particles and future cardiovascular disease. In a recent rigorous systematic review involving the use of Grading of Recommendations Assessment, Development, and Evaluation (GRADE) criteria, the quality of evidence linking red and processed meats to potential adverse health outcomes was found to be “low” to “very low,” and not sufficient to support recommendations to reduce their consumption (14).

Animal foods provide high-quality nutrition

Animal products are the best source of nutrient-rich food for children <2 y old (15), while also providing the general population with important nutrition. A key benefit of animal foods is their protein amount and anabolic superiority (8, 12, 16), an advantage that becomes evident with consideration of essential amino acids content and ileal digestibility. The “Digestible Indispensable Amino Acid Score” (DIAAS) for animal protein is usually ≥1, outperforming plant proteins (legumes: 0.6; cereals: 0.3–0.5) and only approximated by soy (0.8–0.9). With use of state-of-the-art DIAAS, rather than conventional protein scoring systems, nuts, seeds, tofu, and pulses cannot be considered good sources of dietary protein (17).
Animal foods also provide essential fatty acids, with distinct benefits related to the content of EPA and DHA. These long-chain omega-3 fatty acids, abundantly present in oily fish and some other animal foods, are critical for normal brain development in childhood, fertility, immunity, and general health. Their shorter-chain precursor, ɑ-linolenic acid (ALA, 18:3n−3; available in plants), is poorly converted in vivo (5–10% for EPA, 1–5% for DHA) (16, 18). Thus, to achieve the equivalent of the commonly recommended 250 mg/d of EPA or DHA may require many grams of ALA daily, well above the consumption level of most Western vegetarians and vegans (19).
As with EPA and DHA, vitamin A is more efficiently obtained by direct intake from animal foods than from plant precursors. The biological value of the latter depends on the dose and species of the carotenoid, genetic and ethnic variability, and dietary context. Vegan diets are often low in fat, which further compromises absorption. For β-carotene, absorption varies between 5% and 65% and conversion between 4:1 to 28:1 (20). Other vitamins that may become problematic with restriction of animal foods include vitamin D, riboflavin, and niacin. Adequate supply of vitamin B-12 is of particular concern, as vegans have lower serum vitamin B-12 concentrations and, consequently, higher plasma homocysteine than omnivores (4, 12, 16). Whereas animal foods are excellent sources of vitamin B-12 (the Recommended Daily Intake can be delivered by a 100-g serving of beef, tuna, trout, or sardines), vegan diets require supplementation to avoid adverse psychiatric, neurological, and hematologic effects of deficiency. Moreover, supplementation and fortification are not always adequate to achieve sufficiency (4, 16). With the possible exception of some foods foreign to Western cuisine (e.g., the sea vegetable nori), dietary sources of vitamin B-12 are limited to animal products. Furthermore, vitamin K-2 found in animal products (e.g., egg yolks and dairy) may play a protective role for bone and cardiovascular health, beyond the effects associated with plant-associated vitamin K-1 (21).
Animal products provide highly bioavailable minerals (4, 8). Multiple servings of vegetables are often needed to match a single portion of animal food, a problem that may be exacerbated by the presence of antinutrients such as oxalates and phytates (16). For some key minerals, it may be impractical to obtain optimal intakes from plant foods (1, 16). For example, calcium, iron, and zinc are readily absorbed from dairy, fish with edible bones, and red meat; bioavailability of these critical minerals is characteristically lower from plant foods (12). For selenium, availability in crops depends strongly on the mineral status of the soil, whereas animal products vary to a much lesser degree in this regard. In addition, iodine status is often problematic in vegans and somewhat less so in vegetarians, with dairy being a good source (4).
Thus, a plant-based food-supply system would be dependent on fortification and supplementation to avoid risk of widespread micronutrient deficiencies (16). Furthermore, plant-based diets would also lack health benefits derived from the matrix of whole animal foods, beyond macro- and micronutrients (8). For instance, animal foods contain commonly overlooked bioactive components that promote neurological health, cognitive functions, antioxidant defenses, and muscle physiology (2, 4). Relative or absolute deficiencies of choline, carnosine, anserine, creatine, taurine, carnitine, and glutathione may occur with avoidance of animal products (2, 4, 16, 22).

Avoidance of animal-source foods undermines dietary robustness and causes unnecessary risk

Considering the important benefits of animal products as nutrient-dense foods and the absence of evidence for harm, their elimination from the diet comes with unnecessary risks (12). By omitting entire food groups, veganism is a highly restrictive approach that may undermine dietary robustness (4). According to a recent analysis, the greatest food-security challenge in 2050 will be the provision of nutrient-dense foods rather than adequacy of calories or carbohydrates (23). Many of the most problematic nutrients are optimally provided by animal products, including high-quality protein, calcium, iron, zinc, and vitamins A, D, and B-12 (23), as well as choline and DHA (22).
From an international perspective, a lack of access to animal foods can exacerbate malnutrition in vulnerable populations (15). Animal foods supply many nutrients that may be lacking in the cereal-based diets in low-income regions of Asia, Africa, and South America. Provision of meat, eggs, fish, or dairy to children is an effective way to reduce stunting and promote cognitive development (1, 8, 15, 24). But even in high-income populations, vegan diets require careful planning and supplementation to avoid major health problems (4, 16). The required nutritional knowledge, dietary discipline, culinary skills (e.g., proper processing of dried legumes), and resource availability are not consistently present in the general population. Even among the most sophisticated consumers, vegan diets may not be suitable for many people, especially children (24) and those unable to convert plant-derived precursors in sufficient amounts into their bioactive forms (as considered above). In fact, suboptimal nutrient concentrations have been frequently encountered among vegan and vegetarian populations—for instance, with respect to long-chain omega-3 fatty acids, iodine, and vitamin B-12 (4, 16). Concerningly, >90% of vegans and 70% of vegetarians were reportedly deficient in vitamin B-12 (compared with ∼1 in 10 omnivores), with use of the most sensitive diagnostics (25). Moreover, vegetarian and vegan mothers often have low long-chain omega-3 fatty acid and vitamin B-12 status (24, 26, 27), putting the health of their offspring at risk, as underscored by clinical case reports describing severe pathologies (4). Although harmful dietary practices can also be found among omnivore parents, failure to thrive and serious malnutrition syndromes appear to be more strongly linked to vegan and vegetarian upbringing (28), with implications to health later in life (29).

Conclusions

Rather than being portrayed as a cause of a public health crisis, animal products should be recognized as being at the forefront of the battle against malnutrition and diet-related disease, including cardiometabolic diseases. These foods are nutrient dense, highly satiating, and provide a basis for diets aiming to restore metabolic health and prevent age-related diseases (8, 12, 30).
The excessive focus of dietary discourse on animal versus plant foods in the prevention of chronic disease is poorly supported by scientific evidence, especially with regard to calls for the total elimination of animal products. The argument against animal foods is largely based on observational studies that lack the causal data required to inform policy interventions. On the contrary, animal products offer quality nutrition, components of which cannot be easily substituted by plants. Food policies that aim to minimize animal-food consumption will expose populations to unnecessary risk, especially in the face of projected global nutritional challenges. Such narrow approaches to human diets may cause harm and distract from greater dietary priorities that find common ground at both sides of the animal versus plant foods debate, such as the importance of avoiding excessive intakes of nutrient-poor, highly processed foods in globalizing foodscapes.

Refutation (Barnard)

Dr. Leroy has recounted several common myths that merit correction. The romantic notion that hunter-gatherers have been free of “diseases of modernity” was contradicted by the extensive atherosclerosis found in autopsies of Masai individuals (31) and in ancient Inuit remains (32). Meat ingestion clearly contributes to atherosclerosis.
The effect of diet on brain size is mere conjecture. Whales, elephants, and dolphins have larger brains than humans, as did Neanderthals; shrews have a greater brain-to-body-size ratio. Meat and saturated fat consumption is associated with accelerated cognitive decline, increased risk of Alzheimer disease, and brain atrophy.
While a genetic mutation fostering lactase persistence prevents lactose-induced diarrhea, evolution provided no protection against milk's longer-term hazards, notably prostate, breast, and ovarian cancer. In 2020, the Adventist Health Study-2 reported that women with the highest (compared with the lowest) milk consumption had a 50% higher risk of incident breast cancer (33).
The benefits of vegetarian and vegan diets are not attributable to differences in smoking, physical activity, or alcohol use. These and many other confounders have been controlled for in epidemiologic studies. Randomized trials confirm that avoiding animal products reduces body weight, blood pressure, and lipids. A 2015 meta-analysis showed that vegetarian diets lowered total and LDL cholesterol by 14 mg/dL (0.36 mmol/L) and 13 mg/dL (0.34 mmol/L), respectively (34).
The risks of elevated LDL-cholesterol concentrations caused by animal product ingestion are not mitigated by particle-size differences. LDL particles are atherogenic, regardless of particle size (35). In the Women's Health Study, higher concentrations of both small and large LDL particles significantly increased the HR for incident cardiovascular disease (36).
The cited meta-analyses of observational studies that had calculated the benefits of reducing meat consumption by 3 servings/wk were described by Dr. Leroy as discounting these benefits. They actually confirm them. One (10) predicted a reduction in cancer mortality by 7%. A similar reduction in processed meat would be expected to reduce esophageal (30%), colorectal (7%), and breast (10%) cancer incidence, and overall cancer mortality (8%). The second (11) predicted a reduction in cardiovascular mortality by 10%, stroke by 6%, myocardial infarction by 7%, and type 2 diabetes by 10%, all statistically significant. The effects of avoiding meat altogether would likely be much greater.
The characterization of the evidence against meat as being of “low” or “very low” certainty was based on the highly controversial GRADE system, which is not suited to evaluating nutrition studies. It mistakenly discounts even the most rigorous prospective studies and would similarly have discounted studies demonstrating passive smoking's dangers. The benefits of avoiding animal products have been amply demonstrated in both prospective studies and controlled trials.
The idea that malnourished populations have used animal products as a hedge against malnutrition or starvation provides no guidance for individuals seeking to improve their health. Even in populations with marginal nutrition, reliance on animal products is a disastrous strategy. As meat-eating increased in China between 1990 and 2016, cardiovascular disease prevalence doubled.
Protein requirements in children and adults are easily met by a diet of legumes, vegetables, grains, and fruits. According to the WHO, "Protein deficiency is almost always accompanied by inadequate energy intake...," meaning the problem is a lack of food, not a lack of meat (37).
Regarding fatty acids, the European Prospective Investigations into Cancer and Nutrition (EPIC)–Norfolk Study found that, while long-chain fatty acid intake was lower in vegans than in fish-eaters, plasma concentrations of long-chain fatty acids were remarkably similar, suggesting better conversion from precursor fatty acids in the vegan group.
Ingesting preformed vitamin A has no advantage; it has potential toxicity not seen with β-carotene and other carotenoids.
While meat and dairy products contain vitamin B-12, absorption is often poor due to gastric atrophy, medications, and other causes, leading to marginal vitamin B-12 status in ∼20% of elderly individuals. Fortification or supplementation is more effective and cheaper.
Dr. Leroy cites iodine as one of milk's helpful attributes. However, cows do not synthesize iodine or any other element. Iodine in milk comes from iodine-containing disinfectants used to clean contaminated udders and milking equipment and from supplements fed to cattle (38). Better (and cheaper) nutritional strategies are the use of iodized salt, which greatly reduced iodine deficiency in the United States, or the use of sea vegetables, as is common in Asia. These strategies avoid the saturated fat, cholesterol, sugars, estrogens, and cancer risk associated with milk.
Similarly, animals do not synthesize iron or calcium. They obtain them from plants, as humans do. Green leafy vegetables are particularly good sources of both. Iron intakes among vegetarians are typically similar to or even slightly higher than those of omnivores (39). There is no value—and there are significant risks—of excessive iron intake. The same is true for taurine (which promotes intestinal production of genotoxic hydrogen sulfide) and choline (which is prothrombotic and promotes trimethylamine N-oxide production).
Animal products lack dietary fiber, vitamin C, and complex carbohydrate. Overall nutrient intake on an omnivorous diet is inferior to that on a healthful vegan diet. In a 2008 study, adopting a vegan diet increased total vitamin A activity, β-carotene, vitamins K and C, folate, magnesium, and potassium, while reducing intake of saturated fat and cholesterol (40).
Dr. Leroy's citation of inadequate nutrition related to “vegetarian and vegan upbringing” had nothing to do with the adequacy of vegan diets. Rather, it described a 1970s Israeli religious group that limited breastfeeding to 3 mo and then used an improper infant formula. The answer is not meat or bovine milk; it is breast milk or formula. As noted by the Academy of Nutrition and Dietetics, “…appropriately planned vegetarian, including vegan, diets are healthful, nutritionally adequate, and may provide health benefits … for all stages of the life cycle.”
To nourish a growing population, feeding plants to animals and then consuming their muscles, milk, or eggs is resource-intensive, adds unwanted cholesterol, saturated fat, and pathogenic microorganisms, and displaces healthful nutrients.

Rebuttal (Leroy)

Dr. Barnard's dismissal of the rareness of diseases of modernity in ancestral populations and the link between animal foods and _Homo sapiens_’ cognitive development as “myths” and “romantic notions” was less unexpected than his reference to George Mann (31). Being a critic of the diet–heart hypothesis, Mann precisely described the Masai as almost free of cardiovascular disease, despite intimal thickening and high intakes of animal fat. Likewise, the authors reporting on Inuit mummies not only mentioned that atherosclerosis could as well have been due to indoor fires, but also that they remained agnostic about clinical outcomes, especially as cardiovascular deaths were rare among mid-20th century Inuit (32).
The rebuttal relies heavily on nutritional epidemiology of chronic disease. As practiced in the West, the latter mostly expresses responses to cultural norms of “eating right” rather than identifying diet–chronic disease relations (41). Its limitations have been mentioned; adjustment for isolated lifestyle factors (e.g., smoking) remains inadequate to correct for the full spectrum of confounders and biases. Dr. Barnard's interpretation of the Nutritional Recommendations (NutriRECS) studies misses the point; the merit of GRADE, described as “controversial” but officially endorsed by >100 organizations worldwide, is to relate associations to quality of evidence. Statistical significance as such is not a sufficient basis for causal interpretation and guideline formulation if the evidence is low quality. Epistemologically, there is no reason nutritional sciences should settle for lower standards.
Controlled trials may strengthen observation-driven hypotheses but, as argued above, this has not been the case for animal foods. Isolating LDL cholesterol from a broader view of disease risk factors is poorly informative. The evidence disagrees with the claim that LDL particle-size differences do not mitigate risk (42, 43); and the importance of triglycerides and other components of the metabolic syndrome should not be disregarded. If anything, associations between LDL cholesterol and mortality are of a protective nature for most elderly individuals (44), the group in which most deaths occur and for which animal foods are largely beneficial in view of healthy aging (4).
The assertion that reliance on animal foods would be a “disastrous strategy,” even for populations with marginal nutrition that suffer from deficiencies and rampant stunting incidences in children, originates from a higher-income, urban, and Western-centric perspective (15). Even in the West, however, dietary restrictions driven by ideological choice (rather than income) often lead to malnourishment of infants, children, and adolescents [the list of clinical case reports is long, the pathologies severe (4, 24)]. The position paper on vegan diets by the Academy of Nutrition and Dietetics largely reflects the perspective of Seventh-Day Adventists (45) and has been contradicted by warnings issued by other authorities (e.g., the Belgian Royal Academy of Medicine and the Swiss Federal Commission for Nutrition).
Animals concentrate nutrients from plants, which make them very robust sources of nutrition. The various deficiencies at the population level in people not being able (or not willing) to access them attest to that (4). Neither the boosting of “complex carbohydrates” nor the restriction of animal fat and “unwanted” cholesterol will meet the nutritional challenges of mid-century. The provision of essential nutrition will.

[D]A study in the impact of the float range in a tradeup usecase

Most people know that every skin has a randomly generated float range, and many knows that float caps of individual skins exist and alter this range. Where most people lack knowledge however, is when it comes to 'float caps'.
Float.db (csgofloat.com) published a few years ago an article on the matter, and found that the skins have a given chance to drop in every condition, and that the distribution within these conditions were equally distributed (given a float range of 0-1). What makes this system unintuitive is that when the float ranges shift, the distribution is compressed instead of recalculated, which leads to some float values being more common than others within the same float bracket (FN,MW, etc), which isnt the case with a normal 0-1 distribution. According to the same article, some float steps are completely missing for some skins(ex M4A4 magnesium 0.07-0.08). I havent been able to include this in this post.
This post is targeted more at buyorder users than snipers, as most of the following applies to this group in particular. When placing a buyorder for a skin, an expected amount of the skins are to be resold, as you will buy both 'bad' and 'good' floats. Lets assume that most of the skins sold at buyorder price is by case openers (this is an reasonable assumption, as for many of these 'tradeup skins' only people opening them and trading them up have any interest in them), and that the skins bought by the buyorder fits the normal distribution that valve has made and csgofloat has figured out.
Step 1: Set up a general function picturing the %chance of getting a drop at a given 0.01 float step:
First, the chance pr 0.01 floatstep is calculated within each of the 5 wear levels. The table from the article is used as a datapoint for this. The graph will look something like this, where the x-axis shows the float and the y-axis shows the percentage chance to get the float pr 0.01 interval. The increases/decreases lines perfectly up with the change in condition.
Then, the 'float range compression' part of the formula is added. The formula goes like this:
final_float = float * (max_float - min_float) + min_float 
We now have a fully functioning function that can be adjusted for every skin in the game.
Step 2: The interesting part, calculating the odds of receiving a 'good' float from a buyorder:
With a function like this, it is pretty simple to find the ratio between two definite integrals, one representing the entire float range of the condition (fx FN 0-0.07), and one the target range (fx FN <0.04). By doing this, it is possible to determine the odds of getting a skin within a target float range from a buyorder of that wear class (Math). Lets look at an example, lets say we are buying FN skins, and our target float is <0.04. Lets plot our odds of achieving this when we let the lower limit be 0 (we dont want a capped skin that prevents us from getting the ultra-low float skins), and the upper limit be represented by y (that is on the bottom axis, sorry, but it had to be like this to work..): https://imgur.com/Z0NoOdV
As you can see, the float range has a huge implication on your chance of success - a skin with a float cap of around 0.6 is much worse than everything else, and will 'fail' 3 times as often as one with the full 0-1 range. If we would apply this to the breakout collection millspecs fx, an old favorite, (Breakout case), then the urban hazard and the Negev desert strike will less often give us our wanted result compared to the other skins in the case due to their cap of 0.5.
0.6 is not necessarily the worst float cap you can have, it all depends on your target float and the condition you are buying - this cap is actually one of the best for good float MW:
For both these graphs the min_float = 0, and the max_float is the plotting variable:
Same graph for MW <0.09
Same graph for FT <0.21

Tldr: The float range has a huge, calculateable inpact on your buyorder success, and calculating these will often be helpful finding the best skin for your tradeup.

An Analysis of Overanalysis - my adventure in FPL mathematical modelling

An Analysis of Overanalysis - my adventure in FPL mathematical modelling
TL;DR: I tried making a mathematical model to predict premier league results which can be applied to predict Fantasy Football Points. It thinks you should probably have Tomori, Lundstram, TAA, Abraham and Wilson.

Hi everyone! I’m a Mathematics and Statistics student experimenting with Premier League data as a computational data analysis project. For about a month now, I’ve been testing methods of analysing the accuracy of mathematical models that estimate premier league scores, and this algorithm can be applied with some effect to a larger FPL algorithm I;ve created. I want to preface this by pointing out that this post should NOT be taken as anything close to an absolute truth or a good guide for transfers by any means. There is a lot of data that I don’t have access to, and my project is arguably imperfect in several ways. It’s still a work in progress. I’m just doing it because I get off on shit like this. However, I have made some findings that could be useful in directly comparing two players and deciding which to bring in for a run of fixtures. Warning: this is long and should only be read fully if you're as bored on the IB as I clearly am.
What my method does NOT incorporate:
  • Points that players lose from yellow cards
  • Points keepers gain for saves made
  • Bonus Point System
  • Player availability in a given squad and how this can affect performances of other players, including sacking and introduction of managerial staff
  • International Breaks
  • The effects of resting players in prior PL games, midweek games and international fixtures
  • The increased likelihood of goals being scored without an assist against clumsier defences, and vice versa.
(I really wish I could include these things but I just don’t have a detailed enough set of data to achieve this)
What my method does incorporate:
  • The strength of the player’s form in goalscoring and assisting
  • The strength of the player’s team’s form as well as that of their opponent, in terms of both attacking and defensive prospects.
  • Points awarded for clean sheets
  • Points lost for conceding two goals

Some interesting "findings":
  • Tomori is the best defensive option for below 5.0mil, followed by Lundstram and Soyuncu. Chelsea are generally the 3rd best-valued team in the league with some margin over the others fighting for a CL spot.
  • Callum Wilson has the highest expected points next GW at home against Norwich, because:
  • Following the crushing home loss against Villa, Norwich are the worst-valued team in the league, despite being one of the 10 best sides at attacking.
  • Everton and Man United are currently better than Tottenham and Arsenal, especially in defence.
  • Sterling, Auba, Abraham and KDB have a higher expected points until GW13 than Salah and Mané - could the latter be worth going without?
  • As of GW8, for the first time in the last calendar year Liverpool's defence is the strongest in the league.
  • TAA is expected to score more points than Firmino over the next 3 games, despite being 2mil cheaper.
I would be very happy to look into anything else if anyone has any requests :)

This is the bit where I explain the details of my method. I don’t blame you if don’t want to read it, it gets a bit mathsy.
Over the last few weeks I’ve spent many hours tinkering around with different methods I’ve settled on the most predictively accurate I could formulate.
On a fundamental level, my method works by firstly determining four ongoing variables for each team: offensive strength at home, offensive strength away from home, defensive strength at home and defensive strength away from home.
Each of these is a numerical value, such that (mean expected goals in the premier league) x (offensive strength at home of home team) x (defensive strength away from home of away team) would give a mean expected goals value for the home team to score and thus for the away team to concede. These expected scores can be modelled as a Poisson Distribution. I explored the probability of using a zero-inflated Poisson Distribution but I was surprised to find this unnecessary. I will refer to this value as hExG (Home expected goals), and its away equivalent as aExG. For an example of estimating how many points a given player will score, I will assume that Trent Alexander-Arnold is playing away from home against Man United. The first step is to determine what proportion of the team’s strike-force that that player occupies. I found that the most accurate way to do this was to look at their last 5 games on Understat, and divide their xG by their teams’ combined xG, in those games. Trent’s xG over his last 5 games is approximately 0.86, and Liverpool’s is 11.04. So, we can assume that Trent will score a proportion of about (0.86/11.04≈)0**.**078 of Liverpool’s expected goals in any given fixture. Note that this does not differentiate between how well a player compares to the rest of his team at home, because I was unable to find sufficient evidence that such a differential significant enough to consider quantitively exists (e.g. Mané seems to perform better at home than Salah and worse away this season and this is leading people to choose him over Salah for good runs of home fixtures. Last season, however, the opposite was true, so we can attribute this difference to random data variance). His xA over the same period is 1.77, and Liverpool’s is 7.69, so we can guess that he will be responsible for a proportion of 0.23 of Liverpool’s expected assists. We must also take into account that only 75% of goals have an assist in the PL, so we must multiply the amount of points we expect him to score from assists by 0.75 after assuming that every goal is assisted. Since Trent is a defender, we must also give him 4 points multiplied by the probability that Liverpool will keep a clean sheet and -1 points multiplied by the probability of Liverpool conceding more than 1 goal, then multiply it by 2 for conceding more than 3 goals, and by 3 for more than 5 goals etc, both of which I determine using a python function. The formula for the points a defender scores away from home can be expressed as:
Prob(Clean Sheet) = e^(-Opponent's Expected Goals), due to Poisson Dist.
If we put in the values for Trent away against Man United, this gives:
1.56 * (6 * 0.86 / 11.04 + 3 * 1.77 / 7.69 * 0.75) + 4 * 0.32 - 0.33 + 2 = 4.5
So, on average, we can expect Trent to score approximately 4.5 points against Man United.
Through this project, after attempting to compile different statistics to determine how well a team plays in a game, I settled on simply using teams’ xG in each game – I couldn’t obtain any higher accuracy than by using this very elementary method. If you don’t know what xG is, it’s a statistic that compiles the probabilities of each shot taken by a team, based on a variety of information about the shot. The shots sum up to an ‘expected goals’ value that the team has in the game, and it has been shown that this value correlates remarkably well with goals scored. In my opinion it is the shots stat to rule all shots stats, because it determines with unique accuracy the quantitively quality of chances that players get. However, it comes with its problems: there is no way of separating penalties, which are more randomly distributed than shots in general, from other types of shots, so teams’ and especially players’ xG that have recently taken penalties will often be slightly inflated for this reason. The statistic also does not take into account how clinical strikers are, but this in my opinion is an overstated criticism. It is very rare for strikers to underperform vs their xG at a consistent rate, such as to be consistently more clinical than the typical PL striker. Indeed, the only major PL goal-scorer that I can find who has overperformed their xG by ~10% or more than in every season they’ve played is Eden Hazard, and I’m not worried about him.
If you thought the analysis so far was boring, it’s about to get worse, as I explain how I estimate the strengths of teams. I will explain the algorithm in stages.
The first is the most basic step. As already mentioned, I create 4 datasets for each team – home and away attacking and defensive strengths. I look at the xG of each team in each game in the last 2 seasons, and append each dataset with the value divided by the average value. One can visualise this as a very spiky performance line, which I then smooth out by weighting results around a point in time using a normal distribution. To take into account the opponents’ strength, I do the same thing again but this time divide by the opponents’ strength rating as well. Then I repeat this again. And again. Etc. Eventually the values that the algorithm predicts tend towards a constant, which is my algorithm’s evaluation of the strength of each team. Or at least that’s how it works in theory – in practice the attacking numbers slowly decrease and the defensive numbers slowly decrease, but the ratio of mean attacking strength to mean defensive strength tends towards a constant, so when one multiplies the mean goals by the strength values of each team this doesn’t affect the output. I have commented my incredibly messy Python code for this section below if anyone is interested.

How accurate is my algorithm?
My algorithm gives the correct goal count prediction for a team about 36% of the time and gets the goal count right plus/minus one goal about 82% of the time. This doesn’t sound that impressive, but the first of those stats is 3% better than Mark Lawrenson’s predictions over the same period of time as my algorithm draws it data, so while better models surely exist, it’s not too bad. I’m also pleased with the distribution of goals the algorithm outputs, which maps quite closely to the real-life distribution.
Graph of accuracy of goals distribution - AKA why I have opted against a zero-inflated Poisson model

Current raw team strength evaluations (note that each of these columns is weighted a bit randomly, so should only be used for inter-team comparison rather than intra-team comparison):

Team Home Offence Strength (high is good) Away Offence Strength (high is good) Home Defence Strength (low is good) Away Defence Strength (low is good)
Arsenal 1.266 1.001 1.053 1.094
Aston Villa 0.681 1.046 1.200 1.114
Bournemouth 1.188 0.844 1.272 1.222
Brighton 0.935 0.613 0.902 1.246
Burnley 0.853 0.732 1.013 1.071
Chelsea 1.491 1.111 0.679 0.788
Crystal Palace 0.909 0.822 0.930 0.995
Everton 1.299 0.907 1.076 0.767
Leicester 1.032 0.682 0.710 0.885
Liverpool 1.843 1.134 0.536 0.643
Man City 1.954 1.466 0.618 0.658
Man United 1.217 0.987 0.964 0.776
Newcastle 0.804 0.416 1.001 1.024
Norwich 1.313 0.606 1.826 1.530
Sheffield United 1.165 0.439 1.076 0.883
Southampton 1.140 0.786 1.209 0.965
Tottenham 1.078 0.837 0.998 1.004
Watford 1.020 0.803 1.265 1.123
West Ham 0.930 0.810 1.340 1.401
Wolves 1.033 0.903 0.932 0.765
In order to use this data, one can multiply 1.428 (average amount of PL goals in a game) ny a team's Home/Away attacking strength by the opponent's Away/Home defensive strength to generate an expected number of goals for the team, from which you can derive odds of scores using a Poisson Distribution.
Just for fun, I've decided to calculate my team's expected points for next week:
Pope (2.27)
Tomori (4.67) TAA (4.50) Soyuncu (3.72)
Maddison (4.47) Mount (4.24) Sterling (4.91) KDB (4.46)
Auba (4.3) Abraham (4.59) Wilson (6.93 - yes, really (Norwich can't defend away from home))
Total = 49.09 without bonus pts, so better than GW8 :'(
Any constructive criticism on my method is more than welcome - it is, after all, a work in progress :)

Risk: Super Smash Bros. Ultimate Edition - Now Open for Beta Testing!

About 3 months ago, I came here looking to gather a team to assist me with a passion project I had begun planning: a Super Smash Bros. Ultimate themed edition of the board game Risk. I received some interest from people looking to test the finished product, but no one willing to dedicate them self to developing the project. Having no experience with the necessary software, I briefly considered scrapping the project. Little by little, however, I taught myself the basics of GIMP and, today, I'm excited to be sharing the Beta Edition of the game. This post includes everything you'll need to try it out for yourself (as long as you're able to print the materials and have pieces to use as armies).
Box Art
Fighter Cards
Stage (Territory) Cards (some missing images)
Board (Compressed version, message me for an HD copy)
However, I'm still searching for a few resources to complete the project. Unfortunately, SmashWiki is missing high quality (1,920 × 1,080 pixels) images of several Stages needed for Stage Cards. These Stages include: Mario Galaxy, Prism Tower, Halberd, Frigate Orpheon, Green Hill Zone, and Midgar. As well, I'm looking for high quality PNG images of the general Fighter and Stage icons (seen on the official website and in an image I've uploaded below) for the backsides of all Stage and Fighter Cards. If anyone is able to find and send me these resources, I would be super grateful.
I plan to make and upload a rulebook for the game once the kinks are sorted out (outlining the basics of Risk and all changes to the game made for this version), but I'll briefly highlight this edition's unique mechanics.
1) Matches: Unlike traditional Risk, battles between territories (in this case, Stages) are played out in actual matches of Super Smash Bros. Ultimate (each with a 3 minute Time Limit). How many stocks each player begins with each match is determined by counting the number of armies each player has on the Stages which are partaking in the battle. For example: if a player wishes to attack the Bridge of Eldin (an opponent's Stage) from the Fountain of Dreams (a Stage they hold), both players must count the number of armies they have on these Stages and, comparing these numbers to each other, reduce the ratio between attacker and defender accordingly. For simplicity's sake, let's say the attacker has 7 armies on the Fountain of Dreams and the defender has 2 armies on the Bridge of Eldin. After the attacker leaves 1 army behind to hold their Stage, the ratio of attacking armies to defending armies becomes 6:2. Reducing this ratio down to its simplest form (3:1), the stocks for the match are determined: the attacker begins with 3 stocks, and the defender begins with 1 stock. Each stock takes on the value of 2 armies (the lower number in the non-reduced ratio); as such, each stock lost in battle translates to losing 2 armies on the board after the match is over.
If the ratio does not divide out evenly, players must conform to the number of armies held by the defender (put otherwise, never alter the number of armies held by the defender). For instance: let us say the attacker has 13 armies and the defender has 7 armies. The ratio becomes 12:7, but this does not reduce into whole numbers. As such, both players must bring 7 armies into battle; in this case, the attacker sends 5 additional armies back to hold their Stage (with the original 1 army they left behind, this becomes 6). After the stakes of battle are determined, the attacker and defender initiate a 1-1 stock match. The same goes when the attacker has less armies than the defender: if the attacker-defender ratio is 7:12, the attacker must leave behind an additional army so that the ratio can be properly reduced (6:12, resulting in a 1-2 stock match).
This system may seem complicated at first, but I am confident it will become quite straightforward for players after a few turns and will also increase the pace of the game significantly (compared to a game where each army equals 1 stock).
2) Fighter Cards: Fighter Cards are the biggest addition to the tried and true Risk formula (aside from, perhaps, the matches). Every Fighter in Super Smash Bros. Ultimate has their own Fighter Card and an Ability which affects the outcome of the game. At the beginning of the game, each player is dealt 4 random Fighter Cards. From this set of cards, players must choose 1 card to keep and return the remaining 3 to the deck. On their turn, each player can earn an additional Fighter Card by conquering an opponent's Stage. Like Stage Cards, players cannot earn more than 1 Fighter Card per turn; what is more, players cannot hold more than 4 Fighter Cards at a time (if a player picks up a 5th Fighter Card, they must immediately select 1 to discard). Also, players may trade Fighter Cards, should other players be willing, at the beginning of their turn.
Whether attacking or defending, players may only use a Fighter in battle if they hold their corresponding Fighter Card. However, Fighter Cards also add an extra element to the game: as alluded to, each Fighter Card has a unique Ability which can be used to affect gameplay. Some Abilities are designed to be used during one's own turn, while others are intended for use during other players' turns. For example, a player may use Zelda's Ability (Farore's Wind) on their own turn to attack any Stage on the board from a Stage they own (whether or not it is connected to the opponent's Stage). On the other hand, a player may use Roy's Ability (Counter) to potentially do damage to a Stage when an opponent attacks them on their turn. To preserve game balance, players may only use 1 Ability during their turn and 1 Ability between their turns (that is, during other players' turns). Furthermore, Fighter Cards must be discarded after their Abilities are used, meaning the player cannot use that particular Fighter anymore in battle (unless they pick up the card again later in the game).
3) Standard Ruleset for Matches: Stock (3), Time Limit (3:00), Damage Handicap On (used for some Abilities), Items Off, Stage Hazards Off.
3 minute matches may seem fairly short, but keep in mind that most matches will see a player fighting with only 1 (or sometimes 2) stock. Of course, players may agree to adapt any of these rules at the beginning of the game as long as all players agree to the new ruleset.
Lastly, I'd like to say thank you to Smash Wiki and The Spriters Resource for hosting a ton of resources I needed, the YouTuber TylerZM (@TylerZM_) for uploading HD renders of all fighters' mural art, and a Redditor (whose name I can't remember) who inspired me to pursue this project in the first place. If anyone has any questions, feedback, or access to the resources I'm looking for, feel free to comment or message me.

[Investor, US] An in-depth guide to picking a good out-of-state market that I followed to build a portfolio of 40 rentals

Hey guys! I’ve been on here a few times before, sharing my experience building a 35 40 unit portfolio, with 36 of those located out-of-state. Check out this AMA I did for the full story.
I’ve had a bunch of people ask me specifically about how I analyze and choose out-of-state rental markets and what metrics I focus on, so this is a guide specifically for that.
I hope that it helps some folks who are just starting out and live in areas not favorable for buying local rentals. Warning ahead of time – this is going to be long!
 
An Obligatory Disclaimer
Obviously, everything that follows is just my opinion and the way I’ve done things. I’m by no means saying it’s “the only” or “the right” way to pick and analyze different markets. This is just what worked for me.
I always encourage new investors to learn from as many other investors as possible and then put together a strategy that will work for them.
 

Why Picking the Right Market Is So Important

I’ve been investing for several years and have talked to many other investors who’ve been in it for far longer than me. Pretty much everybody I’ve talked to agrees that the macro-economic factors prevalent in the city and state you invest in will have more impact on your long-term performance as a buy & hold investor than anything else.
It’s pretty straightforward to see why. If unfavorable conditions exist at the top (city or state), it will not really matter how good your rental properties are - you will feel the negative effects on your overall performance. This will manifest itself as declining or stagnant home values and rents, longer vacancies, higher tenant turnovers or overall poor tenant quality.
Think about this. If you purchase a property in a city with poor economic growth, rising unemployment and a declining population, do you really think that your rental will be a good long-term investment? It likely won't be. As a landlord, you want two things to happen in the long-term – you want rents to go up and you want your properties to appreciate in value. This can only happen in cities and states that are doing well and where people actually want to work and live.
It doesn’t matter how good the cash flow looks good on paper now. Without price and rent growth, your overall ROI will likely be negative in 5-10 years, if you factor in inflation, wear and tear on the property, capital expenditures and selling costs.
The key takeaway here is that while things like the property's cash flow, return on investment, cap rate and other numbers are important, its location matters above all else. By picking a solid market and neighborhood, you're greatly increasing your chances for success. The opposite is true if you blindly invest without keeping the big picture in mind.
 

Investing Locally vs. Out of State

This question comes up all the time. The grass always seems to be greener in the yard just over there...
First, two things to think about:
The above two can be somewhat contradicting, so what I usually do is encourage people to look at their local market and see if it’s a good area for rentals first. If it’s good or even “not bad” – you’ll probably be better off investing locally, at least to start.
But if the local city or state is terrible for rentals (I’m looking at you, California), then don’t be afraid to start looking elsewhere because the geographical boundaries can be overcome, especially with a good local team.
 

Cyclical vs. Linear vs. Hybrid Markets

Most real estate markets can be classified as cyclical, linear or hybrid based on their historic home price fluctuations. Knowing their differences is important in estimating/predicting future performance:
 

Which Market Type Is Best for Buy & Hold Rentals?

Which market type you choose depends on your specific goals. Cyclical markets tend to have higher appreciation, but lower cash flow. Linear markets have better cash flows, but less appreciation. Hybrid markets are somewhere in between.
Personally, I tend to favor linear markets that also show strong signs of economic, job and population growth. I believe they produce the best conditions for long-terms buy & hold investors, especially those who are not interested in ever liquidating their portfolios.
Why? Cyclical markets (and to a lesser extent, hybrid markets) are volatile, with large, unpredictable price movements. These markets tend to also have high home prices and low cash flow, so the majority of your returns will need to come from price appreciation.
One problem with that is market timing. You may luck out and “buy at the bottom” and see great equity buildup. On the flip side, you can “buy near the top” and find yourself upside down for many years. There are very few investors who can consistently and accurately predict market movements.
More so, appreciation isn’t a realized gain - your equity in your properties does nothing for you if you just leave it there. You will need to continuously refinance (increasing your loan payments and decreasing your cash flow) or sell your properties to see any of that gain returned to you. All while dealing with low or negative cash flow…
On the other hand, “growing linear markets", as I call them, often have an excellent balance between very strong cash flow, moderate home prices, as well as good fundamental indicators that will support long-term price and rent growth.
So not only will you get strong cash flow right off the bat, be able to purchase properties for relatively cheap, but also see good price and rent growth, which will keep your ROI high for many years to come. Win, win!
 

Out-of-State Market Selection Criteria

Hopefully the above gives you some high-level context for picking an out-state-market. Now let’s look at some specific metrics and criteria I use to actually narrow down the choices.
Keep in mind that the following criteria and selection process has been built around finding the “growing linear markets" described above. If you’re looking for something else, you can definitely use the same criteria and process, but will need to tweak it slightly to suit your goals better.
 
Proximity & Familiarity
As I mentioned previously, the closer the property is to where you live, the better, because you will likely be much more familiar with the market and will have first-hand knowledge of the area. If your local market meets most of your other criteria – you’re pretty much set and I don’t see a reason to look anywhere else.
If not, next think about places you’ve previously lived in or grew up in. You’ll likely have similar knowledge about them as your current hometown and will just need to brush up on things that changed.
If nothing else, at least check if there are non-stop flights from your local airport or if you have any relatives or friends living there who can help out, if needed.
 
Median Home Prices
This is the average price of houses in a particular city. The amount of cash you have available to invest right now will effectively limit your purchase price, so you need to find a market that has homes you can afford.
Most lenders will require a 20 - 25% down payment, so multiply your available savings by 4 or 5 to get your max purchase price. For example, if you have $30k to invest, your max purchase price will be limited to around $120k - $150k.
Where to look this up:
 
Weather
Extreme hot or cold temperatures tend to wear down properties faster, increasing maintenance costs. There is also strong evidence that people tend to move to areas with warmer and milder climates, so those cities are likely to experience higher long-term population growth.
For these reasons, I stick to areas that have mild climates, like the south-east and the mid-west of the United States.
 
Natural Disasters
Natural disasters can literally destroy your home or increase expenses due to additional insurance. If possible, avoid areas frequented by hurricanes, floods, tornadoes or earthquakes.
Where to look this up:
 
Population Size
If the town is too small, it may be harder to find tenants for your rental properties and build your local network of professionals to work with.
Small towns also usually have fewer jobs, making them less attractive to people looking to move there. I prefer metropolitan areas with a population of at least 1 million.
Where to look this up:
 
Population Growth
You want a city that will have stable and steady population growth. An inflow of people will ensure there is always a strong demand for rental properties. I prefer places with increasing population growth over a 5 - 10 year period.
Where to look this up:
 
Economic Growth
Just like with the population, stable economic (GRP) growth will ensure an adequate supply of jobs, which will in-turn support increasing population growth and a strong rental demand. If a city's economy is shrinking, it may be a sign of trouble.
Where to look this up:
 
Job Growth
Along with a growing economy, you want to see a growing job market, which is also a great indication that things are going well for a particular city.
Where to look this up:
 
Economic Diversity
One of the things that attract and keep people in an area is economic diversity, or the availability of diverse employment and educational opportunities. Cities that have concentrations of many different industries are less susceptible to negative effects from any one of them.
Where to look this up:
 
Historic Price Appreciation
While over long periods of time real estate prices tend go up in almost any market, short-term fluctuations can be cyclical, depending on the market type (as discussed above). I never advocate trying to time the market, but it's a good idea to look at historic price growth in a city to get an idea for where it is in its real estate cycle.
You may consider passing on an otherwise good market if you feel that recent investor activity has inflated home prices way beyond normal levels.
Where to look this up:
 
Average Rent to Value
You can calculate the rent to value ratio by dividing the average monthly rent by the median home price and multiplying the result by 100 to get a percent:
RTV = Monthly Rent / Purchase Price * 100
This number is a form of rental yield that gives you an idea for how profitable rental properties will be in the area. The higher the rent to value ratio, the better.
You should already have the median home price number, now you just need to look up the median rents and plug them into the formula.
Where to look this up:
 
Local Landlord Laws
Some states and cities tend to favor the tenants, while others favor the landlords. This isn’t a big deal, hence it’s last on the list, but if you’re having trouble deciding between otherwise similar locations, take this into consideration.
Where to look this up:
 

Filtering Markets by Criteria

And finally, here is a step-by-step process I usually follow when narrowing down and ultimately picking an out-of-state market to invest in.
Before we dive in, I’ve uploaded the exact spreadsheet I use when following this process with most of the above criteria already filled in for you (current as of May 2019). Grab a copy right here.
 
1. Look at the Cities You Know
As mentioned several times – first check your local market or cities you’ve previously lived in. Your local knowledge can give you a competitive advantage there, so if they perform relatively well on other criteria, I think you’ve found yourself a winner.
 
2. Start with the 50 Largest Cities
Start with a list of the 50 largest cities in the US. Why? Anything further on the list will have a population less than about 1 million, will be a smaller city/town and probably not a good choice for you, especially if you don’t know anything about it.
Grab the list from this Wikipedia article (already done for you in the spreadsheet linked above).
 
3. Filter by Weather
Eliminate all markets that are too hot, too cold or are prone to natural disasters. This will remove about half or more, depending on how selective you are. I tend to favor the mid-west and the south-east of the US.
 
4. Filter by Growth
Since we want growing, well-performing cities that will create the most favorable conditions for price and rent growth, we’ll focus on growth next.
Look at the population, economic and job growth for the remaining markets and remove any of them with negative or very lackluster growth statistics. I usually just sort by one of the growth metrics and remove the bottom 50%.
With so many cities to choose from it doesn't make much sense to me to invest in areas which are not doing well.
 
5. Filter by Home Prices
Now check the median home prices of the cities that are left. Eliminate any that will put you outside of your budget. Remember, a typical loan will require a 20% - 25% down, so you can take your available cash and multiply it by 4 or 5 for a rough estimate of your max purchase price.
 
6. Filter by Rent to Value Ratio
Next, look at the approximate rent to value ratio of the remaining markets and pick the top 5 cities with the highest RTV ratios.
Since your list already contains some of the fastest-growing cities, this will give you a list of 5 cities that are growing well, but at the same time have strong cash flow and relatively low home values (demonstrated by high rent to value ratios).
Essentially, you’re asking – What are the fastest-growing rental markets that are still under or fairly priced?
 
7. Learn More About the Remaining Markets
At this point, you’ll have 5 potential out-of-state markets to choose from. It’s very likely that you will be successful buying rental properties in any one of them if you followed the above steps to narrow them down.
At this point I usually spend about a week or two digging into each of them deeper to learn more about them:
Based on my experience, after a week or two, you’ll start leaning toward 1-2 of the markets out of the remaining bunch for a multitude of reasons. Again, any of the 5 remaining cities are probably great choices, so focus on a combination of all metrics and criteria I covered in this guide.
One interesting thing to note, is that I’m willing to bet you will not have many cyclical markets left on your list at the end. They will mostly be linear markets, with some hybrid ones here and there (but let me know if this isn’t the case!).
 
 
What now? Well, you have two main options – you can either go the turnkey route and start looking up reputable turnkey providers in the market you chose, or you can begin the process of assembling your own local team, looking for deals, buying them, rehabbing, etc.
I’ve done both and have been successful with both, although building your own team, finding undervalued deals and doing your own rehabs is definitely where the money is at.
If you’re interested, read my other guides on picking a specific property and analyzing cash flow projections for potential investment properties.
 
And as always, feel free to ask any questions or let me know if I can clarify anything!

[Discussion] The Case Fatality Ratio of the Coronavirus (calculated using more accurate formulas during an outbreak) is ~20%. Previous estimates of the mortality rate (2%) deemed inaccurate and ''misleading''.

https://www.worldometers.info/coronavirus/coronavirus-death-rate/
How to correctly calculate the mortality rate during an outbreak The case fatality rate (CFR) represents the proportion of cases who eventually die from a disease.
Once an epidemic has ended, it is calculated with the formula: deaths / cases.
But while an epidemic is still ongoing, as it is the case with the current novel coronavirus outbreak, this formula is, at the very least, "naïve" and can be "misleading if, at the time of analysis, the outcome is unknown for a non negligible proportion of patients." [8]
(Methods for Estimating the Case Fatality Ratio for a Novel, Emerging Infectious Disease - Ghani et al, American Journal of Epidemiology).
In other words, current deaths belong to a total case figure of the past, not to the current case figure in which the outcome (recovery or death) of a proportion (the most recent cases) hasn't yet been determined.
The correct formula, therefore, would appear to be:
CFR = deaths at day.x / cases at day.x-{T} (where T = average time period from case confirmation to death)
This would constitute a fair attempt to use values for cases and deaths belonging to the same group of patients.
One issue can be that of determining whether there is enough data to estimate T with any precision, but it is certainly not T = 0 (what is implicitly used when applying the formula current deaths / current cases to determine CFR during an ongoing outbreak).
Let's take, for example, the data at the end of February 8, 2020: 813 deaths (cumulative total) and 37,552 cases (cumulative total) worldwide.
If we use the formula (deaths / cases) we get:
813 / 37,552 = 2.2% CFR (flawed formula).
With a conservative estimate of T = 7 days as the average period from case confirmation to death, we would correct the above formula by using February 1 cumulative cases, which were 14,381, in the denominator:
Feb. 8 deaths / Feb. 1 cases = 813 / 14,381 = 5.7% CFR (correct formula, and estimating T=7).
T could be estimated by simply looking at the value of (current total deaths + current total recovered) and pair it with a case total in the past that has the same value. For the above formula, the matching dates would be January 26/27, providing an estimate for T of 12 to 13 days. This method of estimating T uses the same logic of the following method, and therefore will yield the same result.
An alternative method, which has the advantage of not having to estimate a variable, and that is mentioned in the American Journal of Epidemiology study cited previously as a simple method that nevertheless could work reasonably well if the hazards of death and recovery at any time t measured from admission to the hospital, conditional on an event occurring at time t, are proportional, would be to use the formula:
CFR = deaths / (deaths + recovered)
which, with the latest data available, would be equal to:
910 / (910 + 3,669) = 20% CFR (worldwide)

Considering that the hazard ratio is calculated as (0=control, 1=experimental): HR = h. 1(t) h. 0(t) (2) (3) The hazard function is (rate parameter ): h(t) = (4) The hazard function in the control group (=0) is: 5. h. 0(t) = . 0(5) The hazard function in the experimental group (=1) is: h. 1(t) = . For two survival distributions, the ratio of the failure rates is called the hazard ratio (aka the relative risk or risk ratio), i.e. For Example 1 of Log-Rank Test, the failure rates of trials A and B are 12/9.828 = 1.221 and 8/10.172 = .786. Thus the hazard ratio h (of A to B) is 1.55. Hazard ratio is a ratio of two hazard functions HR(t) = 1(t;x 1) 2(t;x 2) (3.1) and we remind the reader that the hazard function is defined as (t;x) = lim +t!0 P(t T<t+ tjT t;X= x) t and that hazard is connected to the survival function via the following formula S(t;x) = e: 1)) = 1 1) = + p) The exponentiated coefficients (exp (coef) = exp (-0.53) = 0.59), also known as hazard ratios, give the effect size of covariates. For example, being female (sex=2) reduces the hazard by a factor of 0.59, or 41%. Being female is associated with good prognostic. Confidence intervals of the hazard ratios.

The numerical value can be a fraction of 1.0 or it can be greater than 1.0. For example, a hazard ratio of 0.70 means that the study drug provides 30% risk reduction compared to the control treatment (25). A hazard ratio of exactly 1.0 means that the study drug provides zero risk reduction, compared to the control treatment. This is the math equation used in this hazard ratio calculator. The formula for the mean hazard ratio is the same, but instead of observed and expected at time t, we sum the observations and expected observations across all time slices. From this we can see why the hazard ratio is also called the relative failure rate or relative event rate. Another way to describe the overall hazard ratio is
