The book “The Honest Truth About Dishonesty” was authored by Dan Ariely, a behavioural economist and Duke University professor. Ariely’s book delves into the topic of dishonesty and why people lie, cheat, and steal. He employs research papers and experiments to explain how people rationalise their dishonest behaviour and how tiny acts of dishonesty can lead to larger ones. Ariely also discusses how to avoid dishonesty and promote honesty in our personal and professional lives. The book offers a thought-provoking explanation of human behaviour as well as practical recommendations on how to be more honest in our everyday lives.
