      @rcownie doesn’t argue it’s impossible because he knows the math. It’s impossible because he finds it morally reprehensible. But we could deduce that from the pronouns in his bio.

      Maybe he thinks that it would be bad if the facts were generally known. Or, maybe, he thinks that clicking your heels together can actually _make_ it so.

      There's a real effect here; I remember Henry talking about it. Suppose you've got two polygenic traits under selection, say, intelligence and disease resistance. The selection pulls the population in two different directions.

      Replying to @arguablywrong @gcochran99 and

      Suppose, if ignoring other effects, intelligence would be under some selection pressure _s_ and disease resistance under a similar selection pressure _s_. If the two selective vectors are ~ orthogonal, the realized selection pressure would be ~s/sqrt(2).

      Replying to @arguablywrong @gcochran99 and

      Note that this generalizes to _n_ equal and orthogonal selective pressures _s_: the realized selective pressure is ~s/sqrt(n). If you've got 16 different things pulling in different ways, it still only drops the realized selection on any one by a factor of 4.

      It is kind of entertaining seeing someone pretend 25% is approximately 0, though.

      Replying to @arguablywrong @gcochran99 and

      Seems to me the selection pressures aren't equal at all - once you've got language and culture, selection pressure on cognition may be rather small; but selection pressures on disease/parasite resistance, climate, nutrition etc have clearly been proved very strong.

      🤣😂 the invention of language *reduced* the selective pressure for intelligence - sure.

      Once you've got language to efficiently transmit the accumulated knowledge of a culture, new humans don't have to figure everything out from scratch.

      Yes, and all increases in complexity and demands on cognition stop at exactly that point rather than ... increasing.

          Once you've got effective transmission of culture and hence the highly directed and very rapid mechanisms of cultural evolution, then it reduces a whole lot of other selection pressures, yes.

          Vikings didn't need to evolve fur b/c they could wear woolen clothes, they didn't need to evolve flippers b/c they could build boats, and they didn't need to grow sharp claws b/c they had iron swords and axes. Culture is a BFD.
