From Reddit's "Today I Learned" section:
- Is this an accurate summary of OKCupid's research?
- Is OKCupid's research valid? (other than the obvious criticism that their data has a built in selction bias of being confined to OKCupid userbase).
- Is that conclusion corroborated by other research?
A more general form of the claim is discussed here (basically, that Pareto principle applies to dating).
