memory based, summer memory based, summer problem solving, and some are timed. who came out on top? well, let s call it a draw of the six disciplines, semantic problem solving favourite brain surgeons while mental manipulation went the way of rocket scientists. but for the other for discipline such as memory recall, there was no significant difference. it s significant difference. it s interesting significant difference. it s interesting that significant difference. it s interesting that our problem solving speed might be a little quicker. if something is at the bottom of a deep dark hole and someone s brain stem, you have a second or two to decide what to do to stop that in order to keep that patient alive. i think we get used to doing that sort of thing quickly over the years. so it s not the way that we are born smarter and that way than other people, it s that way than other people, it s that we develop the habit. interestingly, the scores were also compared to 18,000 data se
