I'm sure I've seen at least one person on LessWrong -- perhaps Eliezer -- finding the idea abhorrent of giving oneself temporary brain damage by pouring chemicals like alcohol into their brain. Would this study (supposing it is as reported) change their mind?
"Damage" and "differing function" are two different things. You can increase your capacity for high-quality rational thought by increasing your blood glucose levels, which doesn't really seem qualitatively different from boosting your creative abilities by increasing your blood alcohol levels.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
