Why are you so stupid?

Hey, anyone knows why most 4chan users are so damn stupid? I can't figure it out, I have been here for a long time and there have been really awesome discussion, but most of the time all I see is bland stupidity. I'm not even talking about /b/ stupidity, I mean the real, ignorant, retarded kind of stupidity.

>>6 case in point. At least try to be less predictable or at least remotely witty.
