America's most controversial philosopher has been banned from his campus at SUNY Fredonia.

The university says they have to do it because if he stays on campus, there's a risk he'll inspire terrorism.

Let's look through some of this man's philosophical contributions!🧵 Image
One of his contributions is the idea that it is morally permissible to discount women's applications.

Indeed, the strong form of this argument says that people are obligated to discriminate against women. Image
He has also argued for a policy of killing people. Specifically, killing bad people.

"Just War" theory may say assassination is bad, but, Stephen argues, that needs to change. Image
Much of Stephen's work is philanthropically defending the defenseless and other of society's victims.

For example, he's a defender of people who have a romantic preference for Asians. Image
He sometimes delves into heavy topics, like the conditions under which trash talk is moral and permissible. Image
He's willing to say the things that no one else will, like that slavery is OK and it's not clear why it isn't, speaking as a liberal. Image
Speaking of slavery, he's also talked about reparations.

TL;DR: no one owes them; it's not clear who inherits the right to them; if said right existed, it's dispersed among many and it's less plausible with each generation; and since slave descendants do a lot of crime... QED. Image
He's willing to take this further and make it into a full-blown principle: if you can't quantify the damage, you're not owed anything. Image
He's willing to argue that sexual fantasies—non-perceptual thoughts that are sexually arousing—aren't immoral, unless you're a consequentialist. Image
Without him, would we understand the morality of faking orgasms? Image
Should we torture people during interrogation?

He argues that it's not morally impermissible. There are many scenarios in which it's fine, but this ultimately hinges on whether it works. Image
In fact, he's written an entire book-length defense of torture. Image
Many colleges have taken a turn against hazing and sought to ban the practice.

He argues that, since hazing involves informed consent, they should permit it. Image
He's argued that being religiously pro-life doesn't really make sense.

How can abortion be killing and it still be wrong to harm abortion doctors? Something doesn't add up! Image
He's argued, rather than comparing population means, we should compare population totals, size differences and all, for health cost-benefit analyses.

Say a minority group suffers from a rare but treatable disease. Why treat it when you can give out aspirin to majority members? Image
One of the arguments for affirmative action is that it promotes experiential diversity on college campuses.

But, he argues, this is probably not justifiable, and the idea that minority beliefs will rub off on majorities doesn't even seem relevant. Image
He's also argued that it's not exactly clear why Americans are grateful to veterans and, in fact, they shouldn't be! Image
So why is Stephen Kershnar being kicked off campus?

The campus police chief claimed—rightly or wrongly—that his presence was a danger to others.

You know who might be willing to argue this case?

Stephen Kershnar. Image

Greater Male Variability rarely makes for an adequate explanation of sex differences in performance.

One exception may be the number of papers published by academics.

If you remove the top 7.5% of men, there's no longer a gap! Image
The disciplines covered here were ones with relatively equal sex ratios: Education, Nursing & Caring Science, Psychology, Public Health, Sociology, and Social Work.

Because these are stats on professors, this means that if there's greater male variability, it's mostly right-tail
Despite this, the very highest-performing women actually outperformed the very highest-performing men on average, albeit slightly.

The percentiles in this image are for the combined group, so these findings coexist for composition reasons. Image

One of the issues with understanding Greater Male Variability on IQ tests is that groups that perform better tend to show greater variance

Therefore, to estimate the 'correct' male-female gap, you need to estimate it when the difference is 0

In the CogAT, that looks like this: Image
In Project Talent, that looks like this: Image
And comparing siblings in the NLSY '79, that looks like this: Image

About a decade ago, a theory emerged:

If men do more of the housework and child care, fertility rates will rise!

Men have been doing increasingly large shares of the housework and child care.

Fertility is lower than ever.Image
In fact, they're doing more in each generation, but fertility has continued to fall. Image
The original claim, that men's household work would buoy fertility, was based on cross-sectional data that was inappropriately given a causal interpretation.

The updated cross-sectional data is as useful, and it affords no assurances about the original idea.

We should move on.

American military veterans have a suicide problem.

Some have theorized the reason is deployment-related trauma.

Leveraging the random assignment of new soldiers to units with different deployment cycles, Bruhn et al. found that was wrong.

Deployment did not increase suicides. Image
Looking only at violent deployments (ones with peer casualties), there aren't noncombat mortality effects either.

What explains veteran suicide rates? Image
The reason seems to be that the proposition is wrong: veterans do not have increased suicide risk.

This may seem surprising, but it's not!

Their suicide rates are elevated over the general population because most of them are young White men. That group has a suicide issue. Image

That aspect is probably not that unrealistic, unfortunately.

Across the OECD, on average, just 55% of 15-to-16-year-olds got this question right, and no country saw 80% get it.

Most people globally *do* struggle even reading simple tables. What else?

Thread.🧵 Image
That table-reading question is "Level 3", which, amazingly, corresponds to an already-high level of ability, by global standards.

This is a simpler Level 1 question, but with this, 92% of the OECD got it, including just 65% of Brazilians and 53% of Peruvians. Image
Level 2!

Just 77% of the OECD got this, with less than half of the Mexican population being up to the task.

In fact, only Asian countries got over 90% on this trivial question. Image

Credit card rewards are a great way to redistribute billions of dollars from people who are bad with money to people who are good with it.

With the advent of rewards cards (red), there's lots of cross-subsidization of people with high credit scores by people with low scores. Image
Curiously, the degree of cross-subsidization is not just an income thing.

People with high incomes (green) and moderate incomes (yellow) take fewer rewards at low credit scores, although they take more at high credit scores. Image
What does this do demographically? Spatially?

Credit card rewards transfer money from uneducated to educated, poor to rich, Black to White, and rural to urban. Image
