The trouble, I think, is that so many educational processes put a high premium on getting the correct answer the first time. If you give the wrong answer on an examination question, you lose your mark and that is the end of the matter. If you make a mistake in writing your program—or indeed, in many other situations outside a classroom—it is by no means a catastrophe; you do, however, have to find your error and put it right; maybe it would be better if more academic teaching adopted this attitude also.
