Cheating, and the lying that always accompanies it, is probably as old as the human species. At the same time, that is probably how long we have known that they are harmful traits. The Eighth Commandment (out of the famous ten) tells us not to bear false witness, which means, don’t lie. Most older societies had someone assigned to monitor the marketplace for reliable weights and measures—because left to themselves, most capitalists, of all times and places, cheat. This reality was and still is confirmed by the Roman warning “caveat emptor,” let the buyer beware.
This perennial problem is still with us and can only be held at bay by education, regulation, and standards set by role models and other worthy authority figures.
