I always thought he was putting way more emphasis on the "visual acuity" part than it deserved, maybe he was grasping for something from the material science world to be able to include.
> that the drug improves visual acuity and can sexually arouse, but there's no evidence for it.
If you're referring to formal, peer reviewed studies, of course not. But the sexual arousal and community bonding aspects I'd say there's plenty of anecdotal information consistent with the possibility. This of course in no way proves that his theory has any validity to it on a historic basis, but it at least doesn't rule it out as being impossible.
The whole theory is best taken with a healthy quantity of salt (and it's best to listen to audio of it), but it is a really interesting theory/prediction. One's opinion of the plausibility is likely proportional to their experience with psychedelics, those with a lack of experience would likely have some difficulty with the "how" part.
