As humans, we love to categorize and name things to make sense of ourselves and the world around us. We all work on defining and establishing our identities in order to feel like we are understood and capable of understanding others. It’s why we love personality tests, enneagrams, horoscopes, and more! I think on the surface, it’s mostly about striving for self awareness and a desire for our “true selves” to seen by others.
I think there’s also an innate curiosity and desire to understand those who are different than us, and tools like personality tests can be helpful in that. I think the true root of it all though, is deep desire for community. Identity helps us find and create our community!
