A mechanism that causes people to become more decisive (but much less contemplative) when short on food seems like it would be beneficial. It stops analysis paralysis, and makes someone try something rather than just accept their fate.
Essentially the point I was making. There's truth to that pithy aphorism: decide in limited information and act. Making a decision and an action is better than not. And the feedback from the world you get for that choice will be the balm to your previous lack of information. Iterate to grow knowledge, and keep moving to progress.
Question I was considering was whether evolution had a goal in this? I guess it did. Nervous-system-noise helps explore that state space and extreme states (hunger, sleep deprivation) lower inhibition, leading to greater exploration of the decision space. Biochemical/genetic mediators of more efficient (in aggregate across all humans ever) search algorithms.
Those despotic genes! Programming us, the nerve of them! :) Hahaha :)
