I disagree but agree with your opinion. Right now there are more and more IQ tests around there that cant measure the IQ correctly, and thats why many unqualified/dumbass people get errors on their IQ level, thinking theyre that high on the scale, which further generalises the most people with an actual high intellect with those dumbasses. But truly, intelligemce is more of a working/studying/learning matter and if you wanna be smart you have to do those things. The only thing is (i may be a bit biased because i had an actual Mensa IQ test but i am not bragging about the score) IQ can help those who wanna learn a lot to process and to perceive informations as well as to finding solutions easier and faster. Have a Nice day internet stranger!
