* And even if we look at other, more validated models of personality, it behooves us to remember that personality traits are on a continuum. If we assume one can score high, medium, or low on any single dimension of personality, then we have 243 (3⁵) different types of people in this world that we are trying to influence and adapt to! That’s only looking at the “big five” personality traits—if we look at the BFAS 10 aspect model of personality, we get 59,049 (3¹⁰) personality types. Or, as my friend, psychologist Scott Barry Kaufman, pointed out, if we want to get really crazy, we can assess ourselves using the AB5C model of personality, which has forty-five total facets of personality. That gives us 2,954,312,706,550,833,698,643 personality types.
