Nassim Taleb has been criticizing IQ tests lately. In this nice short blog, @JamesPsychol shows that everything Taleb claims is either incoherent, or factually wrong, or pointlessly ad hominem, or already addressed by psychometricians decades ago.http://www.unz.com/jthompson/swanning-about-fooled-by-algebra/ …
What you said makes no more sense than his argument did. Try to rephrase?

Simply: IQ has no property of a measure. And you consider it as a measure. However, no matter how many times someone repeats this it will be of no avail to you and your peers. It is another domain of thinking.

It's a great measure, it's the best one we have in the behavioral sciences, and it's proven useful in dozens of domains. Sorry you've drunk his kool-aid. If you want to wake up from his cult, read the

That the positive correlation you’re implying reduces as IQ gets higher. Making it a useful metric for say who can be productive in the military but not for who will be a titan of industry, or other outlier producer in society. Is that even a controversial notion?

It means the residuals are displaying heteroscedasticity which violates a key assumption behind OLS which is the conditional variance of your residuals given X to be the same as sample variance of your residuals.
