(edit: in fact, as anecdote - girls supposedly have more tastebuds, yet professional cooking is heavily male dominated. Though women cooks can put up with just as much if not more than men. Physical traits have no bearing on this particular cultural quirk.)
Conversely, all of that /can/ be explained as cultural artifacts, amplified by years of exposure, an encroaching western monoculture, and a feedback loop of expectations. When you stick "pink" and "blue" in front of a kid and ask them what seems more girly to them, you're already presenting a pre-existing baggage of cultural conditions, be it through subconscious impulses, or because the kid's been around long enough to know what his or her peers prefer.
Let's not lose sight that scientific experiments have to be interpreted, yeah? The process of science isn't nearly so clean that we can reliably say that any one experiment isn't tainted by subjective bias. Half of the fights over any one theory in any field at all is because of it.
