Particularly engineering, computer science, math. I came across this quote from someone who specializes in psychometrics in response to this question.
Is it scientifically proven if hard work in STEM fields can compensate for a medium/low IQ?
"No.
If by “low IQ” you mean a score of 80 or below, there are absolutely no compensatory mechanisms, including hard work, for STEM fields. A person at such an intellectual level is unlikely to finish the first year of college-level work in any academic disciple.
IF, by “medium IQ,” you mean a full-scale score in the 90–110, it isn’t likely that compensatory mechanisms such as a high level of industriousness (hard work) will be advantageous. Exception being for those with exceptional working memory and an island of excellence for abstract/logical thinking in the higher end of average."
My question is whether or not this claim is true. If a person has average intelligence (an IQ of 100) and no "island of excellence", do they have very little chance of having a successful career in STEM no matter how hard they work?
Whether it's in engineering, computer science or obtaining a PhD in math, physics and so on? Thanks...
