Any mental model that assigns zero weight to the probability of being wrong is a wrong mental model.

That said, biases arising from endogeneity might have negative effects too. You can't conclude a parameter should have a different/zero sign just because of endogeneity, you have to go fix your model, and re-estimate the parameters.

This is true when there is uncertainty. It also doesn't connect to "I only hire people who think like I do", which is the context of my response, so I don't follow your point.

Agreed on your other point that you need to instrument endogeneity. Another requirement is plausibility. Hookworm presence in Greenland should be uncorrelated to solar sunspots.
