I remember the first multi-choice exam I ever sat. It was in History, and I thought it was a brilliant idea, especially when I got the result. As far as I can remember, each question had four possible answers, so my chances of getting the the right answer went up from zero to one in four! It was easier to think about which one to pick than to think up an answer. History and I parted company soon after.
We all like choice, and the more choice we have the better, eh? Sometimes we make the right choice, sometimes the wrong one. Sometimes we get spoiled for choice, and we end up flipping a coin. Sometimes, though, we are spoiled by choice, not for it.
