As Leo wrote in pinned post what is “self-actualization?”, he wrote its person who ”Have increased spontaneity in behavior — they can be unpredictable and outrageous.”  Why unpredictability feature of self actualized person? 

[LastThursday]

Unpredictability is a sign of complexity and nuance. To an outsider a person can seem unpredictable, but that is because they don't understand what they don't understand. A self-actualised person tends to be more complex and nuanced in character than average. An actualised person has a greater range of choice of behaviours and can afford to be more spontaneous.
