I was thinking of philosophers like the Greeks (Socrates, Plato, etc...), Jewish (Maimonides, Goan, etc...), Chinese (Confucius, Sun Tzu), Europeans (Descartes, Hume), American (Autobio of Benj Franklin, other autodidacts like Hamilton, Jefferson, etc).  Now, a good argument against my list is that few of these sources have actual methods for becoming more intelligent, aside from general advice on how to live &quot;a good life&quot; (paraphrasing) which will allow one to be wise.<p>I hadn&#x27;t seen the systems you mentioned so I will check those out, thanks.<p>I can see how my comment came across as implying it was all drugs and video games, which it is not and I should have chosen my words better. I was trying to convey the overall feel that I got from the site that becoming more intelligent can be done with quick interventions (which is entirely possible, but I think unknown).<p>This wiki is in its early stages so I can&#x27;t fault it much. What I would like to see is a source of evidence behind each link it lists for improvements in memory, creative thinking, problem solving, etc... so that interventions can at least be ranked. The reality is presently we can&#x27;t measure these things very well.  Another nice addition would be early childhood interventions that have been associated with increased intelligence (something we do have data on).
