“The Honest Truth About Dishonesty” by Dan Ariely explores the psychology behind why people lie and cheat—even when they see themselves as moral. Using experiments and real-world examples, Ariely reveals that dishonesty is not just about bad apples, but about how situations, incentives, and even small justifications can nudge us into bending the truth. The book offers surprising insights into human behavior, showing that most people cheat a little, and rationalize it to maintain a positive self-image.
