The word expert is tossed about a lot, even in KPS-style stuff. I came across this little polemic which I thought was interesting. It derives from that dreaded new fad in education, "brain science". The book, The New Brain (oooh I hate refs to Amazon but too lazy to fix it) looks to be in that "this is what brain science tells us about how to be a whizz". As in all of this work, it can be mined for useful stuffand points to the work of K. Anders Ericsson who works on genuises, prodigies, and superior performers.

These ideas loosely couple with that notion of high expectations which is another way of talking about the serious work kids do in KPS-style environments.
