Anyone who's read me ranting about screening will know I'm all for thinking critically about health care. But there's a reason maternal mortality has more than halved in the last 40 years. There's a reason maternal mortality is used as a proxy for health care quality globally.

On average across traits, the three methods produced remarkably similar estimates of ~30%. Most (~85%) of this variance could already be estimated by common variant GWAS run on the same samples. Strikingly, classical twin estimates for these traits were ~2x higher!

The missing heritability question is now (mostly) answered Not with a bang but with a whimper

I wrote a little bit about the "missing heritability" question and several recent studies that have brought it to a close. A short 🧵

I was just thinking that ADHD/ASD might be the ones less likely to attrit

But yes, not a huge problem

How is the attrition in the answers to this survey wave?

Training a single teacher (the "gender focal point") in each school in Mozambique reduced sexual abuse of girls by school staff by 67%

Well, *rational* collective decision making is formally impossible.

Lots of irrational options are ripe for the taking

I was going to ask if someone knows of a comprehensive archive of US state policies that changed over the last 50 years.

But then I remembered there's this: ippsr.msu.edu/public-polic...

So now I'm posting it here for everyone's benefit instead

This is equally fascinating and disturbing.

Do you know how for-pay online surveys like prolific or others are handling this?

I want to read the rest!!! Couldn't find it with a quick browse online. Do you have a link by any chance?

Ah ok sorry

By academic relatives you also mean supervisors right?

But people choose supervisors because they like the topic, no? A lot of self-selecturing going on

And the article provides excerpts of summers end Epstein's messages that makes it abundantly clear that
1. Summers knew who he was talking to
2. Summers clearly hoped to trade feedback and connections for sex

Summers conferred with Epstein frequently about how to extract sexual favors from a Harvard econ grad (AB '04, PhD '09)

The grad is from China

Epstein and Summers referred to her by the codename "Peril"

Racism and sexual exploitation in one efficient package

The Paradox of James Watson The discovery of DNA was evidence of how deeply interconnected humans are, but the late scientist saw only difference.

You're too kind

Professionally? Nope... Just use it to score cheap points with my wife ;)

For some Italian bureaucracy, I had to dig out my phd thesis, and read again the dedication, which of course I forgot about.

Still check out ✅

Solar’s price drop is astonishing: panels are now 98% cheaper than when I first analyzed them in 2004.

Today, building a fence with solar can be cheaper than using wood.

I'm sure many republicans could read this abstract and be satisfied with the results.

Seems like an intended outcome of the policy rather than a side effect
