No source for a claim like this, on a forum where it's the norm for even the most mundane things? Please link one, would be interested in having a look at the study.
> At least on OKCupid, women rate 80% of men as below-average attractiveness, while men rate women at right about 50% as below-average and 50% as above-average
is very different from
> Women view about 80% of men as unattractive. It is not a normal distribution, as men rate women's attractiveness.
Pretty confounding to take that sort of a logical leap in a thread that's about the dark patterns, gamification and the highly modified context into which dating apps transform dating inside them.
