If you are a researcher and you are not cited in this list, it is because you had fallen asleep!

Do you see how Latest Research in Theories of Romantic Relationships Development shows: compatibility is all about a high level on personality* similarity* between prospective mates for long term mating with commitment?
*personality measured with a normative test.
*similarity: there are different ways to calculate similarity, it depends on how mathematically is defined.
Also several studies showing contraceptive pills users make different mate choices, on average, compared to non-users and people often report partner preferences that are not compatible with their choices in real life [uncovered by Eastwick and Finkel (2008); Kurzban and Weeden (2007); Todd, Penke, Fasolo, and Lenton (2007)].
