• Others who will be interested include: professionals who deal on an everyday basis with people gather valuable and extensive knowledge of human behavior

• laymen interested in psychology, with an attitude reflecting their own behavior and habits, can add valuable knowledge to psychology.
• the knowledge of commonsense and the accumulated observations made by world religions, which have remained valid over hundreds of years, can be either integrated in Psychology 2.0 or used as a double-check on psy2's findings.
