German-born English psychologist Hans Eysenck, in his studies of the brain’s reticular activating system, suggested that we all have a set point for regulating arousal levels.
Fifteen percent of us, Eysenck determined, have a naturally high level of arousal, which makes us introverts. He also notes that when introverts develop the skills for managing social activity and relationships and then optimize their penchant for looking inward, they can be among the very happiest of people.
