    I like the implication that this nerd immediately whipped out his phone to post to 4chan when she said this.

    It’s biologically ingrained into us to avoid incest. Revulsion for the act is built directly into our brains due to the severity of the act. I can’t even joke about incest without a pit forming in my belly and my shoulders slumping. Anon was the more neurotypical of the two.

      It’s ingrained to avoid attraction to siblings we grow up alongside, though anecdotally there have been many cases of siblings who grew up apart discovering they were siblings after meeting as strangers and feeling mutual attraction, so the biological instinct may just have evolved around the most common case.

      Not even a little bit. That is only present cultural norms and is entirely arbitrary. Incest is historically common and even considered preferential and a right in the past.

          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.

              No, your arguments about cultural and learned behavior not biologically ingrained Behavior.

                From the above linked article:

                In the case of the Israeli kibbutzim (collective farms), children were reared somewhat communally in peer groups, based on age, not biological relations. A study of the marriage patterns of these children later in life revealed that out of the nearly 3,000 marriages that occurred across the kibbutz system, only 14 were between children from the same peer group. Of those 14, none had been reared together during the first six years of life.

                And lots of other examples across different cultures that would be consistent with this being an instinctual reaction of humans, rather than a cultural thing that is taught.

                  That quoted paragraph is a pretty clear indication that the “instinctual reaction” only happens with people you’ve lived with up to the age 6, which isn’t exclusive to people you’re related by blood. Hell, the following wiki paragraph makes that clear:

                  In Shim-pua marriages, a girl would be adopted into a family as the future wife of a son, often an infant at that time. These marriages often failed, as would be expected according to the Westermarck hypothesis.

                  So, if you don’t grow up with your siblings during those formative years, or see them only on occasion, it is expected to be attracted to them, as per that hypothesis. It’s also important to note that marriages aren’t a simple matter of choosing whoever you like most, there are social and economic considerations to be accounted for.

                  How on Earth do you think that reflects a biological imperative? If anything doesn’t it suggest the opposite? A biological connection resulting in an aversion to coupling would mean the absence of a biological connection should not result in aversion. Yet your example showed that the biological connection was not a factor at all.
