Correlation != Causation. While they very likely might be relevant, I've not seen anything to conclusively prove that it is. The ability to forget is important to humans because we are emotional beings, but I don't think that necessarily is a requirement for generalized intelligence. "sleep" (as in what happens during sleep, not the act specifically itself) on the other hand is very likely important, but again, not proven.
- burning_hamster 5y agoI completely agree that there is no conclusive evidence. However, it is the number one activity that influences cognitive performance in all animals that have been tested. Saying that sleep is not proven to be important for intelligence because the causal link has not been established seems a bit like saying exercise has nothing to do with muscle growth, because the full causal chain has also not been established (we do know a pretty full causal chain in this case, so maybe it is not the best example). I think if you were a betting man, and as a scientist you have to be to some degree, you would put your money on sleep supporting some essential process for intelligence.
