      Wait are you using twin studies for determining genetics in 2018? You can say heritable (which would include epigenetic, microbiome, etc) but "home environment" is genetic?

      Everything is heritable, home environment too. Using it and assuming causality as most people do is obviously a problem. http://onlinelibrary.wiley.com/doi/10.1111/j.1601-183X.2009.00554.x/abstract … https://www.nature.com/articles/mp20152 … There's a meta-analysis with average h² of ~25% for home environment measures, but can't find it.

      Only 2-3% of total variance= "significant" but not impressive. But at least this used actual genetics. Too often people use twin studies that (at best) imply heritability but then use term "genetic". Missing h2 probably microbiome and or methylation IMHO

      Furthermore the study linked to can't exclude reverse causation for the minor 3% variance. IE successful people more likely to mate, thus generating SNP pools that don't have functional importance.

      I'd say almost no one in the field thinks h² primarily reflect microbiome or epigenetics. I don't know of any surveys, but the history of this field is that everybody else constantly brings up new ad hoc models to avoid genetic causation, and they never pan out. YMMV

          Replying to @KirkegaardEmil @karlbykarlsmith and

          No shock people that spent the last 40 years telling us that genetics explains everything only to have a rousing 3% of variance don't think that nongenetic modes of heritance matter. The only "avoiding" is the genetacists denying the clear reality of their failed GATTACA ideals.

          And again, show causual alleles or accept reverse causation. Meanwhile, interventional studies using epigenetics and microbiome are yeilding results that knock out mice never did.
