I think the bug is that finding the right answers is considered important. There is no such thing as a "right answer" unless you can prove it's right. If you don't understand the concepts, you can't know that you got the right answer.

(Then, in "real life", you are really on your own. If you are doing something new and original, you won't know if you are right immediately. You have to convince yourself by applying what you've learned. The answers to test questions, in this case, are completely meaningless. I don't think enough people realize that.)
