possibly. but the researchers haven’t shown that in this particular study because the people they studied (speed daters) WERE ALREADY SELF-SORTED. see here:
65%+ of them were college graduates versus 20% of the population at large (“bhps” — british household panel survey — column). 83% of the men were in skilled or professional jobs while 86% of the women were — compared to 40% and 52% of the general population respectively.
as bruce said over @dennis’: “Key concept: range restriction.”
yup. these people didn’t have to worry about finding a “like” partner out of this sub-group of the population ’cause they were all already pretty alike. they could just pick the nearest warm body to mate with ’cause they had already self-sorted.
