How true is this?

Scientifically speaking, Why are all the boards on 4chan actually the opposite of what they should be, scientifically speaking?

NOTE: I can only speak for boards i frequent
>/sci/ is the brainlet board
>/biz/ is the brokefag board
>/tv/ is the literate board
>/sp/ is the high IQ board

Is there a scientific reason behind this? Can it be modeled mathematically?
