In other words, when a female is picking a male that is "better than her"(hypergamy) does she compare the male to herself(relative) or does she compare the male to other males(absolute) within her environment?

For example, some studies show that relationships don't work out when woman outearns the man. That's a point for the relative hypergamy.

I'm afraid I can't think of a good way to measure the absolute hypergamy beyond the typical mashup of Tinder/OKCupid, chimpanzees, and aborigines.

Or maybe both mechanics are at play: being "better than her" is the bare minimum to even register on her radar, and from that pool of "better males" she picks the best?
