So Scott Alexander's post at http://slatestarcodex.com/2016/03/01/2016-nootropics-survey-results/ shows that the most "effective" "nootropics" have still been the ones that have existed for a long time. What do these results really mean, though? Is it possible that people are just worse at noticing the subtler effects of the other drugs, or are just much worse at disciplining themselves enough to correctly use the racetams or noopept (as in, with choline)?
How much potential is there in innovation in nootropics? What is holding this innovation back, if anything? It feels like there hasn't been any real progress over the last 15 years (other than massively increased awareness), but could targeted drug discovery (along with people willing to be super-liberal with their experimentation) finally lead to some real breakthroughs?
If it was easy to make a human brain work better by tweaking a few chemicals, evolution probably would have done it.
Humans are in a very different situation than they were for most of their evolutionary lifespan.
For one: there is an abundance of resources: tweaks that increase brainpower at the cost of calories which might kill on the Savannah would be solid gold by today's standards. You'd be smarter AND hotter!
For two: the kind of things we want people to use their brainpower on are not the same things the brain was evolved to optimize to think about. For example, despite being dis-tractable, my girlfriend can concentrate on and pay attention to animals for hours, a... (read more)
