not possible to tell different polygenic penetrance from cohort effects in http://biorxiv.org/content/early/2016/08/18/070177 … but it showed lower...
So, if heritability goes up with age, why doesn't Polderman database show this? http://match.ctglab.nl/#/specific/age_groups …pic.twitter.com/eO7YWQLLDe

heritabilities with age. probably some traits go higher, some lower and it overall cancels out.

_I_ was the person to point that out. ;) Does not explain Polderman results for youngsters.

Different traits studied in different age groups. In old samples, lots of disease studies and diseases may have lower h2.

These are not diseases. These are "cognitive".

Could be a reliability issue. Many full IQ battery twin studies of the young, few of old people.
