We had a prior discussion on cognitive performance doping led by the BM on the old site. This was sparked by a Nature commentary which followed a prior editorial.
Nature now has a web poll going asking you to opine on cognitive enhancers. From Retrospectacle:
Brenden Maher at Nature emailed me this morning to clue me in on an anonymous survey that their editors are doing on the topic of cognitive enhancers (a spawn of the commentary piece on the same subject a few weeks back.)
If you'd like to take the survey, check it out here.
