...beliefs are like clothes. In a harsh environment, we choose our clothes mainly to be functional, i.e., to keep us safe and comfortable. But when the weather is mild, we choose our clothes mainly for their appearance, i.e., to show our figure, our creativity, and our allegiances. Similarly, when the stakes are high we may mainly want accurate beliefs to help us make good decisions. But when a belief has few direct personal consequences, we in effect mainly care about the image it helps to project.

-Robin Hanson, Human Enhancement

I feel like Hanson's admittedly insightful "signaling" hammer has him treating everything as a nail.

I think he's mischaracterizing the issue. Beliefs serve multiple functions. One is modeling accuracy, another is signaling. It's not whether the environment is harsh or easy, it's which function you need. There are many harsh environments where what you need is the signaling function, and not the modeling function.
