There is simply not enough evidence backing any of this up.

Even if there was a lot of evidence, I'd still think it'd be bullshit to put INTP, INTJ, INFP, and INFJ as the "smartest."

I’m tired of all the bias against extroverts and sensors.

There's a lot of biases and generalizations in this sub. For example, in the "What's your favorite type?" posts, the comments are filled with generalizations, biases, etc... People just generalize a lot, and it's no surprise that there's going to be tons of it here when personalities are categorized into only 16 types, in a world of 7.53 billion people. With my mbti, INFP, people think we're all depressed and unemployed or something lmao.

Sure, by the conventional way of looking at intelligence, INTPs might fit that standard

I heard that there's a high amount of INTX in STEM fields, and I noticed that a lot of people tend to correlate intelligence with STEM. I was a math and computer science major. When I tell people that, they go like "Wow you must be so smart!" And I just think in my head "What the hell, just cuz I did math and CS?"

People are just full of biases and make generalizations all the time. Yeah it can get really annoying to see it happening all the time in this sub, not gonna lie. But it's normal.
