...but some people really like to use personality indicators like this as a shortcut to describe themselves to others. "Want to know what I'm like? I'm an ESFP Gemini! Look it up and read all about me!"
I have a bit of an aversion to being categorized and defined, I don't like assumptions being made about me based on limited parameters. I don't fit neatly into categories, I'm too often an outlier; and that's true of everyone really. But it seems, from what I've noticed, that a part of typical human nature is to want to be categorized. (Just listen to "Harry Potter" fans talk about what Howarts house they belong in, lol.) They do it all their lives, look for labels that suit them so they can feel they belong, exhibit themselves, or just avoid having to explain themselves. (Telling people your zodiac is Cancer somehow sounds more legit to others than just claiming to possess a trait, and is a lot easier than saying you're emotional, loving, intuitive, imaginative, shrewd, cautious, protective, sympathetic, etc.) It's just a shortcut form of expression really, and people are usually eager to categorize themselves before someone else beats them to it.
Not saying I like it.
Anyway... that's my analysis for the day, lol.
