Sherlock Holmes once said that it is a capital mistake to theorise before one has data. In this episode of The Deductionist Podcast, we put that into practice. Forget “gut guesses” and overhyped body language tricks, we’re diving into the real science of reading behaviour.

From Holmes’ observations in The Adventure of the Cardboard Box to modern psychological research, we explore how baselines, context, congruence, clusters, culture, and emotional leakage actually work in the field. You’ll learn why stereotypes fail, why memory is your best ally in spotting deception, and how slowing down your perception lets you pick up signals others miss.

Whether you’re an investigator, a leader, or just fascinated by human behaviour, this episode gives you practical, Holmesian insights to sharpen your mind and ditch the guesswork.
