Watch your priors-I?m pretty sure there has been research on the role of non-reproducing ?uncles? in providing support for group genetic fitness.
Gwynne: There probably has, but that doesn't mean that desperate people on
the ground were working from that playbook. Perception is reality, unfortunately.
Statistically, a man is slightly more likely to be gay if he has older brothers. If you
look at that from an evolutionary POV, the older brothers would be enough to
breed to maintain a replacement population, so the extra younger ones would
be insurance, and more people to do the work, without impacting the population.
But none of that would probably seem relevant to desperate people. When you're
clinging on by your fingernails you do what you think will work, in desperation, rather
than trust some studies that might or might not be true.
