This trend is similar to the loss of creativity in education. My theory is that it's also a side effect of having teachers who aren't experts in their field; after all, how can you expect someone who doesn't understand physics to teach physics? They'll teach by rote from a textbook, which leads to exactly this. Do the same for the arts and math and every other subject, and you gradually wear the imagination, curiosity, and creativity out of students.<p>It doesn't help that the masses tend to resent the intellectuals... I remember well the looks my friend and I got when we got our AP physics test results back, and the average was 59%, the high was 96%... they knew who got the 96, and they blamed us for blowing the curve.
