How many are put in prison for murder each year in the United States? Data from 1991-2019, by race/ethnicity.
Curious how gender critical feminists et al. respond to a transwoman winning in women's chess. Compared to physical sports, the male advantage is less obvious. Also no physical danger, like in contact sports. I'm fine with female-only categories, but for other reasons.
In a previous post, I discussed the effect of nurture on social outcomes. Now I have written a larger follow-up, discussing how genes affect socioeconomic outcomes, and how this impacts differences between social classes, schools, regions and more.
People mentioning the solar eclipse reminded me of a funny anecdote of Isaac Newton. Newton, in correspondence with John Locke, talks about experimenting with looking at the sun through a mirror until he saw bright spots, and his eyes were seriously injured for several days.
Suicide among young people, United States compared with Europe. Overall, youth suicide rates have fallen in Europe. This is probably the biggest challenge to the hypothesis of social media, smartphones, and so on, being the cause of increased youth suicides. Needs explanation.
Jonathan Haidt (@JonHaidt) claims mental health has deteriorated recently, especially affecting young females. Using CDC data, I looked at how suicide rates in the U.S. for young females have changed between 1999-2020. Both in raw rates, and in relative change since 2000.

@Scientific_Bird @santiag28085574 @eyeslasho In East Asia, that is.
@Scientific_Bird @santiag28085574 @eyeslasho Right, since the absolute numbers are so much lower?
@razibkhan @lymanstoneky @mattyglesias Even if the true narrow-sense heritability were very low, the idea that it's not coded for by a single gene would be irrelevant, so her claim would still be silly anyway.
u need to know SNPs for editing but not selection. All u need for selection is heritable variation. R = h^2 * S where response is due to narrow sense heritability times selection
@mattyglesias @razibkhan ya, but GWAS currently is at <20%, so most heritability isn't stuff you could actually target via gene editing or selection.
Actually it’s the men who don’t understand the rationality of preferring to run into a bear. While per encounter bears are much more dangerous than men, the absolute risk of being attacked by either is very low, & while I’ve seen dudes before, it would be cool to see a bear.
@sebjenseb @Scientific_Bird I think that's just something people want to believe (the idea that there is a point at which higher intelligence stops making a difference in most things). I never believed that though.
@Scientific_Bird David Lubinski at Vanderbilt has been debunking the myth that 'IQ doesn't matter above 120', in many studies, over many decades. Yet the myth persists.
