One argument for the ecological approach to culture I wish the authors had made: it has an established track record in economics, which explains “culture” (markets, institutions) by appeal to individual decision-making under incentives, and not by cultural variants replicating.

@DavidPinsof I just don’t see the contradiction here. People have different incentives depending on which institutions there are

From what I remember I'm surprised they didn't lean more on Singh's subjective selection framework, too, which in many ways would constitute an improvement over neoclassical economics in taking subjective (including inaccurate) beliefs seriously without simply collapsing into the atheoretical/non-evolutionary heuristics and biases programme

@DavidPinsof There is plenty of copying with variation and selection in economics. There's a whole field that studies it from that perspective: evolutionary economics.
