My main issue is the state of the science in 2019 was that epigenetic had a way stronger influence on genetics than previously thought, so i thought you had a new twin study showing that behavior was so overwhelmingly decided by genetics that epigenetic influence did not matter. I did not find any relevant twin study in your book citations, also, they are all old and not up to date (i'm not either, my last meaningfull dive into that subject was pre-covid). To be honest, I mostly asked because i thought i had missed a new study between 2019 and today, so giving me pre-2015 books wasn't helpfull :/
