No. IQ scores are meaningless quantities wrt what field or area of study people end up in. It's an imperfect measure used as one component of diagnosing developmental or learning disabilities and even more useless for anything outside of that.

Is it true that high IQ and STEM are correlated?

Two necessary parts of the answer:

• Yes.
• Be careful how you think about "IQ", since effort is too often undervalued unjustifiably.

edit:
Even with that, I still do not disagree with @QuarkyMeson .
