LESSON 1 · Detect Deception

The Lie Frequency

In everyday social life, the average person tells roughly one to two lies a day. Most are harmless: "That looks amazing" when you're indifferent, "I'd love to, but I'm swamped" to dodge an invitation.

Accepting that everyone lies — including you — removes the moral outrage that clouds clear thinking about deception. Lying is not a flaw reserved for bad people. It runs on a spectrum from harmless to destructive. The practical takeaway: don't try to catch every lie. Spend your attention where the stakes actually matter.
