The link demonstrates that there is a well-reproduced phenomenon in real science whereby, e.g., test scores in various academic subjects correlate positively with each other, and that this can be explained by a common psychometric factor that is reasonable to refer to as "intelligence". The IQ or "intelligence quotient" is an attempt to quantify that which is known to exist, and it's actually one of the best understood ideas in the science of the brain. Additional viewing that largely covers my points below: [VIDEO] You started off saying: > There a lot of pseudoscience around IQ too, probably starting with the very concept of IQ for measuring "intelligence" (for which we would need a strong definition anyway) The point is that we do, in fact, have all the necessary scientific research to argue that the concept of "intelligence" exists - i.e., that we can identify a single-factor quantity that can be fairly described with a single number - and that anything calling itself IQ is definitionally a measurement of that single quantity. In particular: problem-solving capability is a real thing, and some people very obviously have more of it than others. Also, we notably don't have data to support more than one factor anywhere near as strong as Spearman's g . (That is to say: we see correlations between academic performance in all subjects - rather than strong positive correlations within certain groups but weak or negative correlations between those groups).
