Many advances have been made in the knowledge of the human mind, for example researchers and psychologists have undertaken knowledge to gain more knowledge about the brain and human behavior: they are both related to each other. To diagnose mental illness today, I feel that more research and knowledge should be undertaken, such as new studies and procedures to have greater efficiency in diagnosing mental illness in the present. What I have also learned in past psychology courses is that clinical psychology got its name/origin from research and statistics. Statistics determines what information was found to be significant or not, while research disproves or verifies the theory or not. Without research and statistics, I would say it would be quite difficult to determine or understand another individual's behavior, let alone diagnose them and how to treat them.
