Smart people can be very stupid. Take my brother for example. He is very smart, but he is an idiot. He has no common sense. All his intelligence is book smarts.
Very insightful comments profpar. The portion quoted is essentially the point the late great George Carlin famously made, but also pointed out that this does not happen by accident, but by design...because it is exactly the way the "owners" want it. As Carlin put it, they want people who are just smart enough to run the machines and fill out the paperwork (procedural), but not smart enough to figure out how badly they're being screwed (critical/conceptual/higher level).If an educational system solely focuses on subject content and only asses algorithmicly it is feasible to produce an "educated" person who is restricted to pattern and algorithmic (procedural) methods of problem solving.
