Music to my ears. This is brilliant. Either 90% of us can claim to be better musicians than Beethoven or… maybe just maybe polygenic scores aren’t perfect?
If someone you know buys into claims about "genetic optimization" of embryos using polygenic scores of cognition, just send them our 2024 paper on Beethoven & musicality. We wrote it to help communicate limits of individual-level genetic predictions & complexity of links between DNA & behaviour. 🧪👇
Notes from Beethoven’s genome
Wesseldijk et al. compare the genomic information collected from Ludwig van Beethoven
with population-based datasets used to quantify musical achievement.
