You’ve seen or probably heard of countless personality types, be it in astrology (horoscopes) or somewhat based in psychology (type A, B, C, or D?). But what about the full extent of our emotions? An emotion wheel has 3 tiers, with the first tier being 6 basic emotions. Several other emotions extend from the base, and several more extend from the previous tier, leading to a plethora of complex and interconnected emotions. With this wheel in question, it becomes really difficult for Star Trek’s Vulcans to determine what really counts as emotions or not.
