Also, what about creativity? Or (pardon me, just an example) emotional intelligence? An over-emphasis of the IQ just feels so 20th century.
IQ is simply a way to quantify intelligence.
>I was under the impression that the IQ test has a number of biases (e.g., cultural) that leave it flawed.
There is actually no standardized way to measure IQ. You've heard criticisms of a certain test, but that is just one of many. There are tests that do no use any sort of cultural knowledge at all, such as Raven's Progressive Matrices. Theoretically, a cave man and a Harvard professor could reach the same score, assuming all other factors are the same. It only measures visual pattern recognition, but it is generally assumed that that is highly correlated with overall intelligence.

There are also g factor tests that attempt to measure overall intelligence.

>or emotional intelligence
Pretty much pseudoscience
> Intelligence, also known as general cognitive function or simply g, describes the shared variance that exists between diverse measures of cognitive ability
You're of course free to come up with a different definition.
It doesn't measure anything well rounded about a person and it makes me pretty uncomfortable to think this kind of thing could actually be used to divide people.
