I've always thought that intelligent was the quality I valued the most in people, but I think there's something more important. The best way to describe it would be self-awareness.
I know a few people are very intelligent and well read, but the way they conduct themselves makes it impossible to interact with them for very long. They lack self-awareness.
One is an INTP who is very knowledgeable in the areas of politics and philosophy, but he is so nauseatingly pretentious that it's impossible to listen to him for more than a few minutes without cringing. He speaks in a faux-British accent to sound more "sophisticated", he uses overly complex vocabulary that doesn't fit, and is in general very pompous and embarrassing to be around. Why is he like this? How can someone so intelligent be so clueless as to how ridiculous he's acting? Is it a lack of social skills? I don't think so. I know plenty of people who are clumsy and poor in social situations, but they don't come off so offensively as this guy. Maybe he's not even intelligent in the first place? Maybe he's uncreative and incapable of original thought and he's simply copying the behavior of "intelligent" people he knows of, unsuccessfully?
I know another guy, an ESTP, who thinks he's really badass and hard. The situation is the same as before, except instead of intelligence and sophistication being the qualities attempted to show, it's badassedry and manliness. I think the thing about replicating the behavior of role models is true because it applies here as well. He does things like smoke with his hand outside the car window while wearing sunglasses. He revvs his car at the start of an upbeat chorus in a song. Instead of looking smooth and natural, his behavior seems forced and uncomfortable to look at.
The groups this type of behavior I encounter more often in is kids age 9-12 and otakus. I don't know why, but that's been my experience.
Does anybody else know what I'm talking about? This has bothered me for a while.
