Especially in relation to “neurological disorders” like ADHD. Where some people blame their ADHD for their behavior. Or basically anything that has to do with personality. It is clearly as you say tautological. You have a certain personality because you behave in a certain way, you don’t behave in a certain way cause you have a certain personality.
But then you have the fact that earlier personality can be used to predict future personality and future behavior. It is not causal but it is predictive.
Some people call that causal people in social science. I think that is twisting the definition of “causal”.
