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.
This is true, I think that IQ tests are a little outdated because tons of discoveries in psichology fields afirming there is no only one kind of intelligence but many
(As Linguistic, spatial, logical, musical and interpersonal intelligence) and each one would require different approach in order to be tested on individuals.
So it's harder than that, an IQ test filter would be just unfair
Intelligence is problem solving skills... this has nothing to do with linguistic, spacial, musical or social skills... these can all be measured separately
Why would you try to lump all these other things into intelligence? Are you trying to give everyone a participation trophy?
Not everyone is intelligent... sorry, not sorry
Some say intelligence is being book and street smart, what i like very much. Still, this definition does not really include some aspects of the working memory, logic reasoning or processing speed, which are in my opinion the "inner" or innate intelligence (still, it is possible to train those).
But you name it yourself, intelligence is problem solving skills (which is imo not limited to logical or mathematical reasoning). Besides the IQ, isn't someone intelligent, when he knows how to set up a strong and useful network and how to interact effectively with it?
Look at the Wechsler Test (WAIS), one of the most frequently used intelligence test, which well includes spatial and linguistic components! Those components (among others) are combined to a general intelligence, similar as spearman already described it a long time ago with his g-factor theory!
