Whatever the best combination may be, there is wide agreement that the worst is active-negative. The more active a leader, the more criticism he or she encounters Positive personalities take such criticism in stride, but negative personalities are prone to assuming that opponents are enemies. This causes negative personalities to withdraw into an inner circle of subordinates who are supportive and who give an unreal, groupthink view of events and domestic and international opinion. Adolf Hitler and Josef Stalin and, to a lesser degree, Lyndon Johnson and Richard Nixon were all active-negative personalities who showed symptoms of delusion, struck out at their enemies, and generally developed bunker mentalities.
