> depressive realism (seeing the world so accurately that it eats away at your hope [...]) This seems like a lovecraftian argument that humans aren't capable of rational thought without succumbing to the depths of the void, but it doesn't suggest that rationality is suboptimal but rather that too much information is. Like if the world is mostly horrible, perhaps don't read all the news of the horrible stuff - only enough to reduce the potential error in your priors to an acceptable level. The title (limits of rationality) suggests that perhaps we should give irrationality a try. That's not going to be right though, disordered thinking is never called for. If you reach diminishing returns on time spent thinking, stop thinking and pick. If you need unpredictability, roll a die. There are places where more rationality is not the winning move, but none where irrationality is.
