New Study of 17,000 Human Traits — and 100% of Them Are Heritable

From the “Discussion” section of the study:

WE HAVE conducted a meta-analysis of virtually all twin studies published in the past 50 years, on a wide range of traits and reporting on more than 14 million twin pairs across 39 different countries. Our results provide compelling evidence that all human traits are heritable: not one trait had a weighted heritability estimate of zero.

The relative influences of genes and environment are not randomly distributed across all traits but cluster in functional domains. In general, we showed that reported estimates of variance components from model-fitting can underestimate the true trait heritability, when compared with heritability based on twin correlations. Roughly two-thirds of traits show a pattern of monozygotic and dizygotic twin correlations that is consistent with a simple model whereby trait resemblance is solely due to additive genetic variation. This implies that, for the majority of complex traits, causal genetic variants can be detected using a simple additive genetic model.

Meta-Analysis of the Heritability of Human Traits Based on Fifty Years of Twin Studies

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.

If anyone wants a real-world proof of the above cited study read “Racism, Guilt, Self-hatred and Self-deceit”.by Gedaliah Braun (2008). The book is a revelation. It provides a whole series of simple everyday experiments that anyone can do that show the fundamental difference, yea, the unbridgeable gulf, between the mind of whites and the mind of blacks. And these differences are the result of genetics, inheritance, and race. Where Watson and Crick (The Double Helix) used simple paper cutouts of nucleotides and nucleotide base pairs to demonstrate how DNA could be constructed and serve as the basis of the genes, replication, protein production, inheritance, evolution and more, and thereby set off a scientific revolution that necessitated the re-evaluation of every aspect of the biological sciences in light of the new… Read more »

I’ve read Racism, Guilt, Self-hatred and Self-deceit. It does make some excellent everyday observations about blacks and whites, particularly that blacks in Africa lack an ability to think abstractly or exercise forethought, and that blacks make no qualms about being intellectually inferior whites. They know it and will express it openly. In fact, the majority of African blacks don’t want blacks in power because they understand their own nature and most importantly, how blacks treat other blacks. You see, in the absence of a large or any white population, as is the case with virtually all of Africa excepting South Africa, there has been no need for Jews to expose blacks to anti-white propaganda. So their thinking and instincts are accurate, untouched by Jewish political and media influences. I found… Read more »

Hope you enjoy it. It’s the book that ruined his career. That should tell you exactly how important it is. It’s a very academic read in places, particularly chapter two, but well worth it. There is an abridged version that’s very small, just 106 4 x 6 pages that he made for quick reading and mass consumption that doesn’t come near the depth of the full book. Read the full one instead. His online videos are quite good and easily accessible to most viewers, as well.
