Culture Lag and Academic Dishonesty

This question brings together the concept of culture lag with Box 3-2: A Culture of Cheating (p. 60) in Chapter 3.  Even if cheaters and plagiarizers are not caught, what negative effect(s) does their academic dishonesty have on them?  What effects does it have on students who are honest?  How might an entire college or university suffer from academic dishonesty?   How do today’s cheating and plagiarism relate to culture lag?
