Let's ignore all of the arguments around Khan Academy (pretend it's a foregone, rational conclusion that it is superior) and focus on people:

Humans are irrational by default (https://www.youtube.com/watch?v=GDAzsZLvfPw). This is more or less proven in many behavioral experiments (Too lazy right now to source them) when people will do the obviously wrong thing based on internal logics.

Because of this, we can look to the irrational beliefs of people that influence the schools. Namely, social and physical proof. And the social proof has a major benefit: it's less likely that someone is bullshiting credentials if they have an actual degree to back it. http://xkcd.com/451/

Still, it will be a while before irrational opinions catch up (or are leapfrogged by locations like Ghana that embrace the new medium) and that there are ways to catch cheaters.

What exactly are these "irrational beliefs"? Please enumerate them.
