Honesty is a gift we can give to others. It is also a source of power and an engine of simplicity. Knowing that we will attempt to tell the truth, whatever the circumstances, leaves us with little to prepare for. Knowing that we told the truth in the past leaves us with nothing to keep track of. We can simply be ourselves in every moment.

Tell enough lies, and the effort needed to keep your audience in the dark eventually becomes unsustainable. While you might be spared a direct accusation of dishonesty, many people will conclude, for reasons 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.

Big lies have led many people to reflexively distrust those in positions of authority. As a result, it is now impossible to say anything of substance on climate change, environmental pollution, human nutrition, economic policy, foreign conflicts, medicine, and dozens of other subjects without a significant percentage of one’s audience expressing paralyzing doubts about even the most reputable sources of information. Our public discourse appears permanently riven by conspiracy theories.
