Episode: The Good News Is That One Side Has Definitively Won The Missing Heritability Debate
Description: …the bad news is that they can't agree which one. I explained the debate more here, but the short version is: twin studies find that most traits are at least 50% genetic, sometimes much more. But molecular studies - that is, attempts to find the precise genes responsible - usually only found enough genes for the traits to be ~10-20% genetic. The remaining 35% was dubbed "missing heritability". Nurturists argued that the twin studies must be wrong; hereditarians argued that missing effect must be in hard-to-find genes. The latter seemed plausible because typical genetic studies only investigate th...
