Well you can ridicule this statement if you like, but I can suggest a good-faith approach to this question. For example you can trying coming up with a few definitions of what intelligence could be and then look for correlation between this definitions and IQ.
I can go first: intelligence can be reasonably defined as "knowledge and skills to be successful in life, i.e. have higher-than-average income". This definition of intelligence strongly correlate with IQ. There are other possible approaches but all the ones I can think of (e.g. results in math tests) have at least some correlation with IQ.
Now how do you see intelligence? Does it correlate with IQ?
