I'd like to try and avoid this turning into a discussion on exactly what it means to be intelligent, so for the purposes of this thread I'd like to use this definition of intelligence as given by Mainstream Science on Intelligence:

A very general mental capability that, among other things, involves the ability to reason, plan, solve problems, think abstractly, comprehend complex ideas, learn quickly and learn from experience.
So, how intelligent would you rate yourself, and on what basis do you believe this? This can be anything you wish, whether it's an IQ score, the level of education you've attained, personal observation, or even just gut feelings.

Answers can be as vague or specific as you like. For example "I believe I'm reasonably intelligent" or "I think I'm in the top 5 percent".

I think it could also be interesting to discuss how you perceive a person's intelligence and how that differs from the author of the post in question, but only if they give permission.
