It has been found by several studies that individuals who score high in Conscientiousness are more likely to possess a right-wing political identification.
The theory is constructed to advance from basic animal learning principles to deal with all types of human behavior, including personality, culture, and human evolution. Behaviorism was first developed by John B. Watson (1912), who coined the term "behaviorism", and then B. F. Skinner who developed what is known as "radical behaviorism". Watson ...
