9. Human beings tend to be highly goal-oriented, and establishing the proper goal has an important psychological effect. If our goal is to demonstrate that a program has no errors, then we will subconsciously be steered toward this goal; that is, we tend to select test data that have a low probability of causing the program to fail. On the other hand, if our goal is to demonstrate that a program has errors, our test data will have a higher probability of finding errors.
The latter approach will add more value to the program than the former.
