Maybe the *first* program with input they aren't made (or taught) the needed error checks, but then the next lesson should be giving that program input that breaks it and how to protect from it. Maybe then they can be taught that if they KNOW that they control the input, then they can be a bit relaxed in checking. Note that not all errors need to be tested. For instance, in the canonical "Hello World" program, you could add a test for error in the output, but what would the program do, if output is broken it isn't going to be able to output an error message. If in the presence of the error, the program can continue and not get into more trouble, then ignoring the error can be reasonable. But if they learn to THINK about error conditions early, they might not forget as often when it is really needed.
