We can use this knowledge to help explain why similar MBTI personality types appear so very different. Let's take the example below which explores the E/I dichotomy. Whilst in this case, the overall preference is for Extraversion (E), only 3 of the 5 facets are preferred, giving rise to an intimate and quiet Extravert. To some, a person with this preference may come across as a mistaken Introvert. Someone with a preference for all 5 of the Extraversion facets would come across very differently when compared to this example. The same is true for all 4 dichtomies.
