Which professional is distinguished from one engaged in research for treating living patients?

The professional distinguished from one engaged in research for treating living patients is a research scientist. A research scientist focuses primarily on conducting experiments, generating hypotheses, and gathering data outside of direct clinical practice with patients. Their work typically involves developing theories, often utilizing controlled environments and methodologies designed to contribute to the broader understanding of a field, which may include human subjects but not in direct therapeutic contexts.

In contrast, a clinician, therapist, or psychoanalyst is actively involved in providing treatment and support to living patients. These professionals work directly with individuals to address various mental health or emotional issues, employing their expertise to facilitate healing and personal growth. While they may also engage in research, their primary role is patient-centered, making their practice quite different from that of a research scientist. Thus, the role of a research scientist is specifically characterized by their focus on scientific inquiry rather than therapeutic intervention.
