Sasha Gusev declares case closed by comparing studies that assessed different traits using different measurement methods in different countries at different times with different estimands for heritability, ignoring the denominator (total variance).

I wrote a little bit about the "missing heritability" question and several recent studies that have brought it to a close. A short 🧵
The missing heritability question is now (mostly) answered

The trauma and grief these women experienced—having a stillborn baby or losing the baby after birth means you still produce breastmilk. You still have 10 mo of hormonal changes that will not disappear overnight. To have this pain trivialized & erased is truly filthy.

Influencers made millions pushing ‘wild’ births – now the Free Birth Society is linked to baby deaths around the world
A year-long investigation reveals how mothers lost children after being radicalised by uplifting podcast tales of births without midwives or doctors
As Esau Lopez was asphyxiated for the first 17 minutes of his life on Earth, the atmosphere in the room remained serene, even ecstatic. Acoustic music crooned from a speaker in a modest two-bedroom apartment in a suburb of Pennsylvania. “You are a queen,” murmured one of three friends in the room.
Only Esau’s mother, Gabrielle Lopez, felt something was wrong. She was pushing hard, but her son would not be born. “Can you help [him] out?” she asked, as Esau crowned. “Baby is coming,” the friend replied. Four minutes later, Lopez asked again, “Can you grab [him]?” Another friend murmured, “Baby is safe.” Six minutes passed. Again, Lopez asked, “Can you grab [him]?” Continue reading...

I personally think this is a "harder problem" than we care to admit.
So, are you a (social) scientist struggling with this situation? A break between what you _want_ to study (a causal process) and what you feel you _can_ credibly study (a correlation)?
Here are some readings that might help. 👇

And the distribution of SWD for psychotherapies for depression was very similar. In other words, we must say that there was no clear winner in terms of the population preferences -- or if you are brave enough or cynical enough, we must say there were only losers.
The observed smallest worthwhile difference in this study "means that the current 15% antidepressant benefit over no treatment was sufficient for 1 in 3 people to accept antidepressants given the burdens, but 2 in 3 expected greater treatment benefits."
The average SWD for antidepressants for MDD was RD of 20%, and SMD of around 0.5. mentalhealth.bmj.com/content/27/1...
