IQ tests aren't objective at all, it was proven many times before. Many people, who are actually really smart in life can't do IQ tests very well, it's just that they abstract thinking developed differently, or not so much at all. On the other hand you can pick whatever person is shitposting on the internet, and he will probably show you an average IQ score.
I agree with this as it is indeed that IQ tests isn't always right as sone people perfoms well or smart in life even though their IQ tests were significantly not good. Thus, we should also see beyond the tests that we take as sometimes tests really don't determine how we will be in the future.
