Day et al 2018, “Elucidating the genetic basis of social interaction and isolation”
SNP heritability (see GCTA); interpretation is complicated by this being a single-item measure of entirely unknown reliability in the older UK Biobank cohort, so it’s unclear if the heritability is so low due to measurement error, if additive SNP heritability simply is that low and only a small part of narrow or broad-sense heritability.
