    “If You Don’t Have Self-Doubt, You’re Mindless” - Legendary Psychologist Dr. Ellen Langer

    Dr Ellen Langer has spent over forty years at Harvard reshaping how we think about thinking. She is the longest-serving professor of psychology there and was the first woman ever tenured in the department. Her research has shown we can quite literally think ourselves younger, healthier, and more aware. Her work has changed how I think about self-doubt more than almost anything else I have come across. We talk about her research on mindfulness, why most of us are mindless almost all the time, and the line of hers that quietly became the thesis of this show.

    Failing in Front of the Whole World at 20 - Olympic Gold Medalist Lindsey Jacobellis

    Lindsey Jacobellis is the most decorated female snowboarder of all time - two Olympic golds, six world championships, thirty-one World Cup gold medals. She is also the woman who, aged twenty, on live television, made a split-second mistake at her first Olympics that the press has not let her forget for sixteen years. We talk about what it actually takes to rebuild after one public moment becomes your entire identity. Originally released in 2024 when this podcast was called Tiger Therapy.

    The World’s #1 Body Language Expert Still Feels Like He’s Faking It - Chase Hughes

    Chase Hughes spent twenty years training CIA operatives in persuasion and lie detection. He is now widely described as the world’s number one expert on body language and behaviour, hosts YouTube’s The Behaviour Panel, and Dr Phil wrote a chapter of his book about him. I was extremely nervous to interview him because he can look at your face and know what you are thinking. We talk about that. We also talk about the questionnaire he uses to identify limiting beliefs in twenty minutes, and a metaphor he gave me about how we talk to ourselves that has stayed with me ever since.

    Growing Up in a Slum, Magical Thinking & The Power of Dreams - Astrid Tuminez

    Astrid Tuminez is the first ever female President of Utah Valley University. She grew up in a slum in the Philippines and on her first day of school couldn’t spell her own name. By the end of the year she was top of the class. She would later go to Harvard, MIT, Wall Street and Microsoft before her current role. This is the closest thing I have heard to a real-life movie. We talk about magical thinking, the role of imagination growing up with nothing, and the voice in our heads that does the most damage.

    The Confidence To Make a Big Career Change - London Business School’s Herminia Ibarra

    Herminia Ibarra is Professor of Organizational Behavior at London Business School and has held tenured positions at INSEAD and Harvard. She has been named one of the most influential business thinkers in the world, and her work on career change is required reading in the field. We talk about why so many midlife career pivots quietly fail, what her data shows actually moves the needle, and her most helpful advice for anyone wrestling with self-doubt about their career.

    The Truth About Imposter Syndrome - Dr Lisa Orbé-Austin

    Dr Lisa Orbé-Austin earned her PhD in Counseling Psychology from Columbia and has spent her career researching imposter syndrome and how to dismantle it. She has been featured on The Today Show, Good Morning America and NBC News, and is the co-author of two bestselling books on the subject. I almost borderline-stalked her to get her on the show, and was not disappointed. We talk about the myths most popular writers have spread about imposter syndrome - and what the research actually says. Originally released in 2024 when this podcast was called Tiger Therapy.

    Even The Iceman Has Self-Doubt Sometimes - Wim Hof

    Wim Hof - known globally as The Iceman - holds twenty-six world records for what he can do in extreme cold. He has run a half marathon above the Arctic Circle barefoot. He has scaled Mount Everest in shorts. He arrived at the recording so full of energy that I almost forgot to press record. We talk about what he says about his own self-doubt (which most people will not expect), and the principle he applies to himself that he is now teaching the rest of the world.

    The Science of Self-Doubt: How Your Brain Tricks You and How to Trick It Back - Dr Caroline Leaf

She is the author of Cleaning Up Your Mental Mess and other bestsellers, and has been featured in Vogue, Forbes and the BBC. We talk about why she thinks the dominant ‘chemical imbalance’ framing of mental health is bad science, and the five-step process she has developed to rewire patterns of self-doubt.
