Under what circumstances would you lie, or cheat, and what effect does your deception have on society at large?

Take a look at this video we watched during class. Yes, the speaker talks fast but if you have the time, try to listen to him again and hear what he has to say.  How is human motivation and behavior linked to cheating and lying? What kind of society would you like to have your children grow up in? Is there anything we can do?
