Twin Study mentioned in the interview:
- Polderman, T., Benyamin, B., de Leeuw, C. et al. Meta-analysis of the heritability of human traits based on fifty years of twin studies. Nat Genet 47, 702–709 (2015). https://doi.org/10.1038/ng.3285
- Website based on the research cited above: MaTCH. This website provides a resource for the heritability of all human traits that have been investigated with the classical twin design. The traits have been classified into 28 broad trait domains, as well as according to the standard classification schemes of the International Classification of Functioning, Disability and Health (ICF) or the International Classification of Diseases and Related Health Problems (ICD-10). Currently, the database includes information from 2748 papers, published between 1958 and 2012, reporting on 17804 traits on a total of 14,558,903 twin pairs. https://match.ctglab.nl/#/home
