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.
It's loads of data, but it's hard to find out what really makes a big difference. It's also hard to find out what would work on oneself due to lack of objective tests, very strong placebo effect relative to drug effect, and long term most of the drugs need to work.
I love the idea of using the placebo effect for intelligence enhancement. :-)
