Not necessarily.
Do I think that I have more experience than the average poster here? Yes. But that's mostly a factor of age, not due to anything exceptional on my part.
Im pretty smart but im pretty ignorant, too.
I think thats what it comes down to. I know a lot of things, but i dont know a lot more things.
Being "smart" doesnt really matter. It's nice, though. Here's a quote to show my braininess and drive home the point:
"Nothing in this world can take the place of persistence. Talent will not: nothing is more common in this world than unsuccessful men with talent. Genius will not; unrewarded genius is almost a proverb. Education will not: the world is full of educated derelicts. Persistence and determination alone are omnipotent." -Calvin Coolidge
This is one of those polls like "how attractive are you, 1-10" where the average answer is 7. We overestimate how smart we are and underestimate everyone else.
Personally I'm one of the five smartest people on the Internet. Clearly.
Average? I'd say yes but then again I probably shouldn't be using the vast amounts of trolls and shit posts to back that up. Really I'd say I'm just older than a lot of offtopic and have gone through more school. That doesn't always necessarily mean I'm smarter though.
