Everybody is atwitter about the survey results in Nature which showed that 20% of respondents, mostly scientists, had taken cognitive enhancement drugs other than caffeine.





I especially liked Io9’s coverage, ”62 Percent of Pill-Popping Scientists Use Ritalin” Almost half of the cognition enhancing minority had used modafanil (Provigil), and 80% of all respondents in the Nature poll thought people should be allowed to take cognitive enhancers. 

Io9 goes on to compare the good drugs that scientists are taking to think smarter and longer, to the lower quality (albeit more delicious) caffeine consumption of the hoi polloi.
