First, this is a straw man argument: I never argued for "innate ability gap". I argued for "innate affinity", which I understand as (quoting myself) "they do not like working in it".
Second, I never claimed there was evidence to support the correctness of "innate affinity" argument. I only claimed that it is a possibility, and OP should not have ignored it.
Third, there is no consistent evidence supporting "social explanations", and that's why people resist attempts to "change the field to be more welcoming" at the expense of hard-working, deserving white males.
