I feel like this is technically true but also misleading towards the belief that there is an overall perceptual computation advantage of psychedelic states. You can maybe get a higher score on certain tests, but it comes at a loss on other tests. I'm willing to bet basic tests like an eye exam will score worse when all the letters are dripping. The reality is psychedelics effect a particular band of brainwave frequencies, and so is not like the blunt general stimulation or inebriation of other drugs. It may be better for your brain to be in a psychedelic state on certain tasks, but if it was better in the general case evolution would have already made it so. Remember, I can rig a system with absolute perfect perception just so long as you don't mind a rate of 100% false positives.
Still congrats to QRI on this research. Very impressive result. Seems like they had some of the same method ideas I've had, or thought my ideas were worth taking last I spoke with them.
