In this episode, I sit down with Ben Whybrow — pain specialist physiotherapist and educator — for an awesome conversation about the psychology of influence. We dive into the work of Robert Cialdini, especially his book Influence, and unpack how these principles show up every day in healthcare. You’ll find a summary of the book below, and I hope you enjoy the way we explore it through a clinical, human, and practical lens.
Influence: The Psychology of Persuasion by Robert Cialdini.
Influence explores the psychological principles behind why people say “yes.” Cialdini identifies six core mechanisms that advertisers, salespeople, leaders, and everyday humans use — often subconsciously — to persuade others. The book reveals how these principles show up in real life, how they can be used ethically, and how to defend yourself against manipulative persuasion tactics.
The six principles include:
People feel obliged to return favours or concessions.
If someone gives you something, you're more likely to give back.
Once people commit to something — especially publicly — they're more likely to follow through to remain consistent with that identity.
When uncertain, people look to what others are doing.
If everyone else is doing it, it must be right.
People tend to follow credible, knowledgeable experts (or people who appear to be).
We say “yes” to people we like — those who are similar to us, give us compliments, or make us feel good.
People want more of what they feel they can have less of.
Limited availability increases desire.
