Transhumanists have high hopes for enhancing human cognitive abilities in the future. But what realistic steps can we take to enhance them now? On the one hand Flynn effect suggests IQ (which is a major factor in human cognition) can be increased a lot with current technology, on the other hand review of existing drugs seems rather pessimistic - they seem to have minor positive effect on low performers, and very little effect on high performers, what means they're mostly of therapeutic not enhancing use.
So, fellow rationalists, how can we enhance our cognition now? Solid research especially welcome, but consistent anecdotal evidence is also welcome.
A good start is probably having a demonstrated history of life problems caused by lack of attention/focus, ideally consistently shown and starting from childhood. Complain about inability to concentrate, losing track of time easily, &c.
Of course, I assume your goal here is to get an amphetamine prescription. That's not the only treatment used for ADHD, and if you walk in complaining of ADHD symptoms and asking about Adderall you may send up some red flags. Be careful with the law here, prescription drug abuse is frowned upon.
