Thread:User talk:Nebuchadnezzar/Why is the Vervet monkey study "really dumb?"

If you're wondering why it's a study on monkeys and not humans, and why I chose that one in particular, it's because there is no way to definitively rule out the possible effect of societal influence among children old enough to even have toy preferences, as studies in those cases also show that little girls prefer dolls, but in those events, how can we know if that is not a result of preconceived notions?

Monkeys don't have preconceived notions about gender. And that's why I must ask: in what way is that peer-reviewed study "dumb?"
