peaceful and (otherwise) honest people to lie so as to avoid being punished for behavior that is ethically blameless.
Mental Accounting
One of the greatest problems for the liar is that he must keep track of his lies. Some people are better at this than others. Psychopaths can assume this burden of mental accounting without any obvious distress. That is no accident: They are psychopaths . They do not care about others and are quite happy to sever relationships whenever the need arises. Some people are monsters of egocentricity. But there is no question that lying comes at a psychological cost for the rest of us.
Lies beget other lies. Unlike statements of fact, which require no further work on our part, lies must be continually protected from collisions with reality. When you tell the truth, you have nothing to keep track of. The world itself becomes your memory, and if questions arise, you can always point others back to it. You can even reconsider certain facts and honestly change your views. And you can openly discuss your confusion, conflicts, and doubts with all comers. In this way, a commitment to the truth is naturally purifying of error.
But the liar must remember what he said, and to whom, and must take care to maintain his falsehoods in the future. This can require an extraordinary amount of work—all of which comes at the expense of authentic communication and free attention. The liar must weigh each new disclosure, whatever the source, to see whether it might damage the facade that he has built. And all these stresses accrue, whether or not anyone discovers that he has been lying.
Tell enough lies, however, and the effort required to keep your audience in the dark quickly becomes unsustainable. While you might be spared a direct accusation of dishonesty, many people will conclude, for reasons that they might be unable to pinpoint, that they cannot trust you. You will begin to seem like someone who is always dancing around the facts—because you most certainly are. Many of us have known people like this. No one ever quite confronts them, but everyone begins to treat them like creatures of fiction. Such people are often quietly shunned, for reasons they probably never understand.
In fact, suspicion often grows on both sides of a lie: Research indicates that liars trust those they deceive less than they otherwise might—and the more damaging their lies, the less they trust, or even like, their victims. It seems that in protecting their egos, and interpreting their own behavior as justified, liars tend to deprecate the people they lie to. [10]
Integrity
What does it mean to have integrity? It means many things, of course, but one criterion is to avoid behavior that readily leads to shame or remorse. The ethical terrain here extends well beyond the question of honesty—but to truly have integrity, we must not feel the need to lie about our personal lives.
To lie is to erect a boundary between the truth we are living and the perception others have of us. The temptation to do this is often born of an understanding that others will disapprove of our behavior. Often, there are good reasons why they would.
Pick up any newspaper and look at the problems people create for themselves by lying—problems that seem to require more lies to mitigate. It is simply astonishing how people destroy their marriages, careers, and reputations by saying one thing and doing another. Tiger Woods, John Edwards, Eliot Spitzer, Anthony Wiener—these are men whose names now conjure images of the most public self-destruction. Of course, their transgressions weren’t merely a matter of lying. But deception was what prepared the ground for their humiliation. One can get divorced without having to issue a public apology. It is even possible to live a frank and utterly unconventional life of sexual promiscuity, or exhibitionism, without paying the penalties these men paid. Many lives are almost scandal-proof.
