Genetics is the overwhelming influence on what sort of person we are
Leftist hate genetics because it stands in the way of their Fascist desire to "mould" us in some way suitable to their fantasies. But the more advances there are in genetics, the more we see the impossibility of their dream. Their fantasied Eden is just not possible. Our genetic inheritance is a rock in the way of change. We are what we are and everybody just has to deal with that. The study below is the latest advance. It both combines a huge amount of data and shows surprisingly high levels of inheritance for a huge range of human traits. Hans Eysenck, a prolific writer on genetics, once said to me in an off-the-cuff remark: "It's ALL genetic". That is very close to being so
Meta-analysis of the heritability of human traits based on fifty years of twin studies
Tinca J C Polderman et al.
Despite a century of research on complex traits in humans, the relative importance and specific nature of the influences of genes and environment on human traits remain controversial. We report a meta-analysis of twin correlations and reported variance components for 17,804 traits from 2,748 publications including 14,558,903 partly dependent twin pairs, virtually all published twin studies of complex traits. Estimates of heritability cluster strongly within functional domains, and across all traits the reported heritability is 49%. For a majority (69%) of traits, the observed twin correlations are consistent with a simple and parsimonious model where twin resemblance is solely due to additive genetic variation. The data are inconsistent with substantial influences from shared environment or non-additive genetic variation. This study provides the most comprehensive analysis of the causes of individual differences in human traits thus far and will guide future gene-mapping efforts. All the results can be visualized using the MaTCH webtool.
