My parents are both clinical psychologists, and my father used to do some evaluations for the courts. If I remember correctly, he would do evaluations to see if a person is mentally fit to stand trial, and would recommend to the judge if the person would be better served with psychological help than prison time. Some context:

- Being mentally fit to stand trial is an very low bar to pass. You just need to understand what a judge is, what a jury is, etc. Generally people who don't pass either have some sort of intellectual disability or severe schizophrenia.

- The article lists a ton of different situations where psychologists are involved in the legal system, and I don't see a breakdown on what the psychologist is attempting to do. I know my Dad didn't use much more than an IQ test and some basic questions to try and diagnose a couple of clinical conditions. I'd expect some amount of pseudoscience if one side in a messy divorce hires a psychologist to try and show the other side is a bad parent, or the defense in a criminal case trying to show the defendant was in a fragile emotional state and deserves a reduced sentence.
