Last week, I had the pleasure of speaking (virtually) to folks in the @nmsu.edu psychology dept for their Friday Forum. Presented my work on the longitudinal dynamics of G-E interplay across cognitive development. Thanks @jgrabman.bsky.social for the invite!

In 2018, Charles Murray challenged me to a bet: "We will understand IQ genetically—I think most of the picture will have been filled in by 2025—there will still be blanks—but we’ll know basically what’s going on." It's now 2025, and I claim a win. I write about it in The Atlantic.
Your Genes Are Simply Not Enough to Explain How Smart You Are
Seven years ago, I took a bet with Charles Murray about whether we’d basically understand the genetics of intelligence by now.

Philosophy <--> Science
1. The philosophy of science sometimes gets an unearned reputation as a purely academic exercise that offers little by way of concrete tools for advancing research.
This is wrong.
And today, as we grapple with how AI is changing the nature of scientific activity, it's desperately wrong.

This has become my latest pet peeve. "Causal" is sexy and creates the impression that you're uncovering mechanism(s), but "causal estimates" are often just associational and/or reliant on strong assumptions that are rarely met.
E.g., CausalML applied to observational data. Cool, but...

However, AI folk, it is going to be far, far better if we collectively call "back in time" or "left" in the normal way to lay out time as "antecedent" and *not* causal.

Check out our preprint on ethical and legal considerations regarding Mendelian Imputation of missing parental genotypes! The method raises tricky questions about informed consent and potential harm. We highlight gaps in current practice and provide recommendations for researchers and IRBs.

New work by Andy Dahl and Michal Sadowski on using GxE to study genetics of drug response now out in Cell Genomics www.cell.com/cell-genomic...
Characterizing the genetic architecture of drug response using gene-context interaction methods
Sadowski et al. propose a framework to study the genetics of response to commonly prescribed drugs in large biobanks. They quantify the heritability of response to statins, metformin, warfarin, and methotrexate, and identify associated genes. Their analysis also shows the importance of accounting for drug use in genetic risk prediction.

I continue to be surprised that this isn’t more widely known/accepted, even among some researchers I respect.
