Avoiding overfitting has struck me as being possibly behind the creativity and psychological benefits that some people experience from psychedelics too. Psychedelics seem to be capable of kicking the brain out of some kind of local maximum in which it is stuck.
Being "stuck in a rut," having depression or PTSD, or just being uncreative could be symptoms of the brain having overfit to some past set of stimuli.
