At the risk of sounding like the usual HN snobs, I doubt anyone frequenting this site is below average intelligence.
I think precisely half of us are.
lol. Well at least one of us is I guess... So point taken.
Come on, the HN snobbery is annoying but so is this reverse snobbery/false modesty.
I can't help but raise the fact that you've probably conflated mean and median here, although I admit that I've never looked into the shape of the distribution of human intelligence.
Well, at least we know where I fall on the spectrum.
