Jung’s original definition that some people get energy from socializing while others have to expend energy to socialize doesn’t hold up to scrutiny. We’re social primates and sometimes we like socializing and other times we find it taxing but often it’s a little of both.

But I think it’s important to remember that we’re not talking about a real thing that actually exists in our genes or brains. It’s just a vague description of your attitude to socializing.
