This is a case of someone trying to outsmart himself. At some point in our lives, especially when we want to make a hard decision or to venture into a new thing, our inner mind will continue to guide us, but we prefer to play a trick on ourselves choosing that which we know is utterly wrong. That is been a traitor to ourselves. A lot of people don't act the right way for their benefit, for instance, the case of a student who doesn't read his books all through the lecture days only for him to start studying during exams. That would be a very wrong move, you know.
