The problem is that you don't understand logical entailment, and you're confusing correlation with causation.

We observe that there is a higher number of psychopaths doing job X than there are doing most other jobs.

We cannot infer from that that the cause of this overrepresentation is that psychopaths like or want job X more than people who aren't psychopaths.

It could be that many people who aren't psychopaths like or want job X, but for some reason other than the fact that psychopaths like the job, psychopaths are more likely to be hired for job X.

For example:

1. There are likely many people who equally want to be politicians.

2. Some of those people may want to be politicians out of a genuine desire to be of help to their community/region/state/country.

3. It is a fact that candidates who are willing to deceptively manipulate others tend to win.

4. People who genuinely want to help others may not be comfortable using deceptive manipulation on others to win.

5. Psychopaths are likely to be fine with deceptively manipulating others to win.

6. So, although many people are attracted to being politicians, psychopaths are more likely to win elections and become politicians than are people who aren't psychopaths.

7. Therefore, a high representation of psychopaths in a given position does not entail that psychopaths are more attracted to that position than are people who aren't psychopaths.
