Right. The point here is that whatever the marshmallow test does measure, it doesn't seem to measure what many economists would like to think it measures - at least, if the results of this paper hold. Noam, does that make sense?

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

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.
