Episode notes
Measuring SNPs
- Modern genetic research measures single nucleotide polymorphisms (SNPs), single DNA letter differences.
- These SNPs, measured cheaply and easily, tag chunks of co-inherited genetic variants.
Genetics of WEIRD Populations
- Genetic research primarily focuses on "weird" populations, limiting our understanding of human diversity.
- This bias restricts the scope of findings, similar to issues in social sciences.
The Genetic Lottery Metaphor
- Harden uses "The Genetic Lottery" to explain genetic differences between siblings.
- Random inheritance from parents provides causal insights, like a natural experiment.
