Girls learn to talk before boys. Is it talent? No, science discovered, thanks to experiments, that is the level of hormones in the womb. Does it mean that 100% of girls learn to talk before boys??? NO! Again learn statistics, and you will discover there is nothing working 100% of the time, we make reasonable predictions, and do have outliers.
Experiments also on how male children are treated compared to females have shown huge differences, things parents don't even suspect, but they do all the time. They even measure the amount of autonomy in feet distance given to a boy and to a girl, and guess what? 99.7% of the time, no matter the continent, boys are let go further by parents, so you made a lot of examples which can be easy answered if you read a little more. Like I advised Reb, just go to the nearest library, and the librarian will help you to grow out of those beliefs.
Any insight into what makes some people bigger dicks than others?
That's exactly what I did (clearly), and asked other people to state their opinions in equally clear terms.
