I don't think that the fact that Wikipedia has a list of 165 cognitive biases says more about Wikipedia than it says about behavioural economics.

The core idea from Kahnmann is that humans use heuristics to make decisons.

Evolution certainly affected human cognition but most designs for intelligent agents don't produce intelligent agents. The space of set of heuristics that produce intelligent agents is small. It's not clear that you can make an intelligent agent of something like a neural net that doesn't engage in something like the availability heuristic. Confirmation bias isn't something substantially different than the availability heuristic in action.

When Google's dreaming neural nets reproduce quirks of the human brain it's hard to argue that those quirks exit because they provide advantages in sexual competition.

So what does an evolutionary approach tell us about the human mind? For a start, it tells us something about our objectives.

That's basically saying Darwin was wrong and his critics who object to organism that don't evolve according to objectives were right. Darwin wasn't controversial because he invented evolution. Lamarks already did that decades before Darwin. Darwin was controversial because he proposed to get rid of teleology.

Economics makes errors because it assumes that humans have objectives. You don't fix that by explaining how humans have different objectives. You fix it by looking at the heuristics of human beings and also studying heuristics of effective decision making in general.
