There isn't one tight little circle of cheaters and one tight little circle of honest students. Some kids cheat at home but not at school; some kids cheat at school but not at home. Whether or not a child cheated on, say, the word completion test was not an iron-clad predictor of whether he or she would cheat on, say, the underlining A's part of the speed test. If you gave the same group of kids the same test, under the same circumstances six months apart, Hartshorne and May found, the same kids would cheat in the same ways in both cases. But once you changed any of those variables-the material on the test, or the situation in which it was administered-the kinds of cheating would change as well.
