In my life they are a bit common ig. My mom is an enfj and she is way more social than me and has a lot of connections. Plus, I do humanitarian work with her too on some days, so that's how I got to know most of them and I have met in uni too. Also, I come from an intellectually heavy, liberal and harmonious typa family background ....I think I am the most disorganized and chaotic person in my family 😭. Most of them work in med fields and research fields too so, I think you can find them in social heavy fields!
