14. Crowds are easily swayed



People with a dominant or charismatic personalities can easily affect crowd opinions and maneuver groups to do their bidding. They appeal to the group's emotions, taking advantage of the effect in #13. (Oddly enough, research proves that two heads are still better than one)

15. It takes a person 66 days to form a habit



There is a lot of research data that suggests that following a pattern for 66 days will make it habitual.

(This also works for breaking habits)
