The paper you linked to was "flawed" because they couldn't get their numbers right, so they segregated out a group of people and even then they only got partial correlation between their hypothesis and the measured results, hence me being a bit sarcastic
I think men and women are born with not only different physiology but also different psychologial makeups, hence what works for one doesn't always work for another. Try looking for studies of boys with behavioural problems that were raised the same way as girls. Both as infants and adults, the sexes have (as a result of evolution) different inbred traits, not at least how they express themselves.
There is no excuse for not offereing equal opportunities though, i.e. same rights, same pay for same work etc. because that is indeed a construct made by society and shouldn't be in one (society) that consider itself "elightened".
I think I made it my lifes goal to make a mockery of the selfish gene and try to identify everytime I think something that could in reality be the Homo Somethingveryoldus speaking through our racial memory.
