The Danger: Overconfidence
"Brain doping," or taking cognitive-enhancing drugs to improve one's mental sharpness and concentration, is no longer overwhelmingly the domain of college students looking to boost their academic performance. According to several studies, the use of drugs such as Adderall, normally prescribed to treat ADHD, has begun spreading into several professional fields where certain drug side-effects, most notably the tendency to overestimate one's own competence and ability, could prove destructive. The practice has become so widespread in the financial sector, among bankers and others making major investment decisions, that the governments of Germany and Sweden have begun to research the possible repercussions. Also worrisome, a survey found nine percent of surgeons using the drugs.
