Sexual dimorphism, height and the normative presentation thereof.

Yet more graphs showing that some famed data on how different men and women are doesn't really seem to indicate that much difference.

(Or, more pithily - The sexes aren't opposites. And that's assuming you are going to stick to just two sexes to describe humans.)

Height in humans is one of the more clear sexual dimorphisms we have, and boy do we harp on it culturally when it comes to heteronormative dating.

When Charles and Diana were posed together formally, however, they were typically arranged so as to suggest that he was significantly taller than her, or at least to disguise the fact that he was not.

As a male who is significantly shorter than the norm in my culture, I've hit this particular cultural imperative a lot. (And no, I don't sleep with women taller than me just to subvert the dominant paradigm or some such.)

And, since we're in the area, a brief primer on the difference between "norm", "normal", and "normative" as used in sociology.

Something can not be the norm, but still be normal, and even normative. (For instance, the nuclear family in North America.)
