Final answer:
A person who understands the differences in self-serving bias between depressed and nondepressed individuals is likely a clinical therapist, with knowledge of how internal versus external loci of control influence mental health.
Step-by-step explanation:
If you recognize that depressed people do not exhibit the same self-serving bias as nondepressed people, you are most likely a clinical therapist. This observation aligns with psychological research indicating that individuals with an internal locus of control—believe they have control over their life events—are generally healthier, cope better, and are less depressed compared to those with an external locus of control. Clinical therapists understand the nuances of cognitive processes in mental health and how they affect an individual's perception and behavior.
