>>11620231If you start practicing IQ test problems you can increase your score. So you will have a "higher IQ".
This is what people who are obsessed with getting into Mensa do. Chris Langan, who thinks he's a super genius, in all likelihood did the same thing. If he was actually 99.9999 percentile intelligence he would have made a non-trivial contribution to some scientific field by now, but all he's accomplished is word salad.
Obviously you won't be actually smarter. The test only measures your intelligence under the assumption that you had as much preparation for the test as everyone else did. IQ has a strong environmental component (see the Flynn Effect).
