In a time where conspiracy thinking is becoming mainstream, critical thinking is no longer a nice-to-have, it’s a survival skill. In this episode, I sit down with Dr Steven Novella, neurologist, professor at Yale, and host of The Skeptics’ Guide to the Universe, to unpack how misinformation takes hold, why smart people fall for bad science, and how we can sharpen our thinking in an age of echo chambers and AI-generated noise.
We explore the psychology of belief, the decline in institutional trust, and the subtle line between healthy scepticism and reflexive contrarianism. Whether it’s decoding the carnivore diet, vaccine misinformation, or climate change denial, Dr Novella breaks down what it means to be truly evidence-based, and how to stay intellectually honest in a world full of false certainty.
What we cover:
- The difference between scepticism and denialism
- How to talk to someone who believes in conspiracy theories
- Why scientific consensus matters and how to spot real expertise
- The psychological appeal of pseudoscience
- How to build a truth-seeking mindset grounded in humility and logic
- The role of AI in shaping the future of truth
- What we lose if we stop trusting science
If you care about science communication, critical thinking, or simply making better sense of the world, this is an episode worth sharing.
