I’m making a bit of a joke, but it’s worth discussing some broader issues, here. The first is that “we” in this sense, points to an ideology. I’ve taken a lot of ridicule from what would be considered leaders in the fields of behavioral genetics and my own field of psychiatry for questioning…. 1/
“but ultimately the uncomfortable truth is that genes contribute to traits much less than we always thought.”

🧬 Let’s do a GWAS on zip code. Say, the first two digits are 70 (my choice). You will likely get some correlations if the sample is large enough. What percentage of the variance explained will you get for the SNPs for “70” zip code? Say it’s 10% even with your PCA’s. Is “70” zip code genetic? Now…

I mean, is someone showing him fake clips of Portland and Chicago and he actually believes it? Not sure if that idea is more or less disturbing than if he is just lying.

It’s amazing how many articles I’ve read like this in the past quarter century. It’s malpractice to base clinical psychiatric decisions on genetic studies at this point. There is just nothing there.

One of the reasons I abhor the largely null field of behavioral genetics is this kind of reckless stupidity from someone well known in the field. BG is bad science with an inevitable and harmful endpoint. They haven’t found a thing in 65 years. Let it die.

Folks, The NYT’s is not your friend. Whatever mystique they hold is from decades ago. You don’t need to point out that they are writing misleading headlines and doing bad reporting like they just need it pointed out and will return to the fold. Whatever it was, it’s now a center-right newspaper.

I originally wrote this as a preprint for a poster presentation at the ASHG conference last year. It was apparently removed from the server. It’s an easy read, I think, critiquing the field of behavioral genetics.
