Many steps have been taken in learning about the human mind, for example the knowledge of researchers and psychologists has been undertaken in order to obtain more knowledge about the human brain and behavior - both linked to each other. In order to diagnose mental illness today, I believe that more research and knowledge should be undertaken, for example by having new studies and procedures in order to have more effectiveness in diagnosing mental illness today. current time. What I also learned in past psychology classes is that clinical psychology gets its name/origin from research and statistics. Statistics determines which information turns out to be significant or not, while research denies or verifies the theory or not. Without research and statistics, I would say it would be quite difficult to determine or understand another person's behavior, let alone their diagnosis and how to treat them.
