What It Means to Understand vs. Explain in Psychology

June 14, 2026 - 04:59

Psychology sits at a curious crossroads between art and science. On one side, there is the drive to understand a person's inner world, their feelings, and their unique story. On the other, there is the scientific demand to explain behavior through data, theories, and replicable experiments. This tension between understanding and explaining is not just an academic squabble. It shapes how therapists treat patients, how researchers design studies, and how the public views mental health.

To understand someone, in a psychological sense, often means to empathize. It involves grasping the subjective meaning behind an action. Why did a person develop a phobia of dogs? A purely understanding approach might look at their childhood memory of being chased. It feels true and personal. But psychology, as a science, pushes for explanation. An explanation seeks a cause that can be tested. It might point to classical conditioning, a learned association between a dog and fear. This explanation can be generalized to other people and other phobias.

The conflict arises because these two modes are not always compatible. A deep, empathetic understanding of a single patient might not tell you anything about the general population. Conversely, a cold, statistical explanation of depression might feel hollow to the person suffering from it. Modern psychology tries to bridge this gap. Clinicians use evidence-based treatments, like cognitive behavioral therapy, which are rooted in explanatory science. Yet they must also offer a genuine understanding of the client's lived experience to build trust and rapport.

the field needs both. Explanation gives psychology its credibility and predictive power. Understanding gives it its humanity. The best psychologists are those who can move between these worlds, using science to explain the mechanism while using empathy to understand the person. Without explanation, psychology is just storytelling. Without understanding, it is just a list of variables.
