Episode 3: Inside the mind of a liar

In this episode of Fool Me Twice, Bradford and Steve take listeners inside the mechanics of lying and explain how easily confidence and charm can mislead us. Steve defines a lie as a deliberate attempt to mislead while knowing the truth, then challenges many popular beliefs about how liars behave. He explains that nervousness, lack of eye contact, or awkward pauses rarely signal deception on their own. People show these behaviours for many innocent reasons, including stress, fear, or simple distraction.

The conversation centres on cognitive load and how lies strain the brain. When people tell the truth, they recall real memories. When they lie, they must invent details, maintain consistency, and respond to follow up questions in real time. This mental effort often leaks through behaviour. Steve describes how trained interviewers and modern technology focus on changes in eye behaviour, response timing, and speech patterns rather than dramatic physical reactions. Heart rate and sweating, for example, often reflect anxiety instead of dishonesty.

Benchmarking plays a major role throughout the episode. Steve stresses that interviewers must first understand how someone behaves when telling the truth. Only then can they spot meaningful changes. Without this baseline, even experienced professionals can miss deception. Charismatic personalities, confident speakers, and attractive people often distract interviewers and influence judgement. The episode highlights how easily appearance and personality can override logic in criminal interviews, workplace situations, and romantic relationships.

The discussion also dives into lying by omission. Steve explains that many people avoid direct lies by leaving out key details. By saying less, they reduce the risk of contradiction. Others overwhelm listeners with excessive information to steer attention away from the real issue. Both tactics appear frequently in interrogations and everyday conversations.

Through case experience, humour, and relatable stories, the episode connects professional interrogation techniques to real life situations like dating and social interactions. The message is clear. Spotting deception requires attention to patterns, context, and behavioural change over time. There is no single behaviour that exposes a lie, and anyone who relies on shortcuts will likely be fooled.
