We can, however, observe trends in the way skill levels tend to be distributed among people of different psychological types.
It's apparent that, on average, INTJs tend to be better at calculus than ESFPs.
Are there some ESFPs who are better at calculus than some INTJs? Certainly, but that's not the point. If we picked 100,000 INTJs and 100,000 ESFPs at random and added up the total calculus proficiency in each group, which one do you think would come out on top?
I want to know which skills you think ENTJs tend to be weak in on average, relative to other types.
