Abstract: As humans have a limited range of feelings and limited perception, we can’t rank all possible actions in order of preference. However, we can use this inability to rank some actions, to infer rankings of other actions. Surprisingly, having less precise sensory information improves our ability to draw such inferences. Therefore, if nature selected a “Reasoning Man” with perfect inferential abilities, this person would have muted feelings and blurred perception. Behavior would nevertheless maximize happiness and evolutionary fitness, and not be merely satisficing. These results might help explain why the human sensory system has its well-documented limitations.
