Believing that you are smart, is the first sign of not being it. Even the smartest people will admit that they are mostly good at maybe a few areas, and at best average at everything else.

Any position I hold is toppled over with the slightest argument unless I have very recently done a ton of research on the topic. I have zero ability to recall whatever evidence I used to come to a conclusion. It’s incredibly frustrating because I do try to be informed about things but I just can’t defend anything at the pace of a normal conversation.

Being confused often by people and not being able to apply yourself to simple intellectual tasks would be good hints but they could also indicate other underlying disorders and atypicalities different from intellect.

This is further exasperated by the fact that most people specialize in one or more brainy tasks such as mechanical visualization, language comprehension (spoken and/or written), rhythm, mathematics, etc.

There are also behavioral differences that are judged as more or less smart depending on the person. For example, is selfish self serving actions smart or stupid? Do we prioritize long term satisfaction or short term? Does a smart person care about betraying trust of others?

TLDR: Idk man, its real hard to tell, dude

I’m smart enough to know that everyone is both smart and stupid.

I’m stupid enough to believe that doesn’t apply to me.

Last week I moved the cheesegrater so I could look behind it… for the cheesegrater.
