They don't identify that directly. But they do identify the potential to do something productive. Obviously that can't be the only thing being used to judge people; but some objective standard like that has to be part of what is being used.

Also, regardless of what standardized tests do or don't do, judging based on "articulate, socially well-adjusted person who can communicate their values and opinions in an intelligent way and who is comfortable making connections with others" is, IMO, a very poor way of filtering out people who will prey on other people, since anyone who preys on other people has to have those skills (or at any rate be able to fake them well enough to pass a test for them) to be successful at it.

"They don't identify that directly. But they do identify the potential to do something productive." It think your definition of what is productive might be very different than mine.

"since anyone who preys on other people has to have those skills" If you look at history you will find many without those skills that preyed on others.
