      That article doesn’t support your argument. The effect isn’t based on relation but on being raised together before the age of 6.

        Well yeah, but that is still “biologically ingrained to avoid incest”, since being raised separately and then reintroduced as adults is an edge case. The effect is biological even if what it’s directly testing for isn’t genetics.
