Capitalization can really change a sentence. For example:
I love to eat candy.
I love to eat capitalization.

In general lack of religious beliefs is a trait of intelligence.

Liberalism is as well, so I would say that we have on average a higher percentage of liberals than conservatives in the group although I do know a few staunchly conservative atheists.

It’s actually that the rate of higher education is elevated in Atheist populations.

Yeah, man, we gots bunches of smart peoples here. All ya gots t' do is ask 'em.

Welcome, @Castles -- pull up a chair and sit a spell while we impress you with our high IQs and other things even more important.

Yip.

I've seen a few stupid things, but 98% of the time your statement is accurate. I believe skeptics are generally more intelligent than others, so it may well be that we here have a higher IQ.

I don't know I'm dyslexic

Hard to say if that's the case without knowing what other groups you're referring to. But my $0.02 is that you may be right.

Welcome to our little beach party! Bar's over there by the pool...

I really can't point to any one thing for all that. However, I do find that most of the people who frequent this site generally exhibit more skills in language, grammar, punctuation, and have an overall air of intelligence.
Even those who speak English as a second language are pretty clear when expressing their thoughts and positions. Granted, that's more the rule than the exception, but I can usually grasp what most posters are trying to say. It's really very nice to not have to decipher what people are trying to convey. I love this site!

I would think so.

Yes.

Reading this post hurt my brain.

Please... not again. But Welcome and may you enjoy and have fun in our little place. Just be yourself.
