I get the impression that a whole lot of bad things that happen in the world are a consequence of, and perpetuated by, lying and deception.

It is curious that neither our legal systems, nor even our religions, have adopted such a prohibition categorically. Even the Ten commandments do not prohibit lying categorically - just testifying falsely against a person.

In the past century, developed countries have started punishing lying and deception when done for profit, to some extent. Scams are frowned upon and eventually might be prosecuted. Companies are beginning to be punished for misrepresentations in their ad campaigns.

In other areas of private and public life, however, lies and deception are not merely permitted, but routine. Politicians are expected to deceive the public and lie to it. Organizations, for profit and otherwise, fund studies which seek not truth, but rather a biased distortion of truth that aligns with their interests. People cherry-pick studies and refer to only those with favorable results. Car salesmen lie about their goods. People deceive their partners and their families.

These practices create harm both direct and indirect. They create distortions which serve to cast doubt, create uncertainty and deny access to truth about topics of interest, to anyone but the sharpest minds who specialize in that topic. The expectation that you will be deceived or lied to, and must constantly be on the lookout for it, is as detrimental economically as having to constantly be wary of pickpockets and others who would rob you, kidnap you or even kill you for minor benefit. Lies and deceptions create a hostile environment where the mind has to spend most of its time to defend itself, rather than to work towards desired goals. This is unpleasant, stressful, and a waste of our most valuable, fleeting resource: our thought.

So why, then, do we not do more to punish lying and deception? Why do such transgressions result only in moral backlash, and perhaps a resignation - if that, at all? Why are liars and deceivers, professional and hobbyist alike, not treated just like criminals and thieves? Even when the lies are small, but especially when they are large?

When a drug addict breaks your car window to steal your camera, he might be causing $1,500 in damage for what is a $100 benefit to him. Lies are similarly detrimental. When someone spreads misinformation, it is generally for a small personal benefit. But the damage caused by the misinformation is often many magnitudes larger. Damage can be caused both directly, when other people suffer from the deception or lie; but even greater damage may be caused indirectly, through a loss of public trust, and therefore transactions that fail to occur as a result. For example, one act of insurance fraud harms the insurance company; but rampant fraud causes everyone's premiums to rise.

The extent of damage caused by lies is sometimes straightforward to estimate, but more often hard. And yet, if one sticks to either being honest or keeping quiet, this is generally constructive, builds trust, and has beneficial or benign results.

So why do we not make honesty standard? Not just because our parents taught us not to lie; but because a widespread expectation of honesty is essential to the proper functioning of our society, to our prosperity as a civilization, and eventually, perhaps, to our survival as a species?

Why do we tolerate a force as destructive as lies?
