I’ve never read the book, but it sounds interesting. I’ve always been interested on what life is like for those who have a truly high IQ. I consider myself smart, but I know based on my experience with academics I am really only slightly smarter than the average person, I can’t compete with the truly smart people (130+ IQ).
One thing I’ve heard both from reading online and from knowing people in person is that some extremely high IQ people become lazy because they never have to work hard, and when they do have to work hard (or they have a goal that can’t be solved solely by a high IQ) they give up or quit easily. That is one major drawback. One guy online said he had become incurably lazy due to his high IQ, he never reached his potential. He found that he could accomplish more with less time/effort than other people, and he got content in that situation of just putting in 1-2 hours a day at work and goofing off the other 6-7.
A guy I knew in college (I was in an academically demanding field which attracted the best students in my state to study it at this university) would skip all his classes, then by his own admission study for 1-2 hours before a test and get an A or B. I attended all the classes, took notes and studied more than that and was lucky to get a B. When I was talking to him he discussed how he got accepted to medical school and how he wished he had tried harder because maybe he could’ve gotten into one of the best medical schools in the country had he exerted a little more effort.
But I have no idea if he survived medical school and residency. He was used to academics involving skipping all your classes, then studying for an hour to get an A. What happens when he gets to medical school and he can’t do that anymore? What happens when he gets to residency and finds no matter how high your IQ, you still have to work 80-90 hours a week? Did he make it, I don’t know. Another guy I used to know breezed through undergrad but dropped out of a grad school program because he said he never had to work in undergrad, and never learned how to do it.
Also IQ is just one of many factors of cognitive skill. Others include working memory and self discipline, there are probably lots of others. I believe the marshmallow study found that self discipline was more important than IQ in determining academic success.
I have known several smart people who became alcoholics and drug users, smart people are more likely to end up as substance abusers.
