Microlives & The Art of Uncertainty with Sir David Spiegelhalter

What's your life expectancy trade-off for enjoying a crispy bacon sandwich? 🥓

Sir David Spiegelhalter is a celebrated Professor of Statistics at the University of Cambridge; widely accepted as one of the UK's foremost statisticians. He explains the concepts of 'micromorts' and 'microlives', which quantify risk and the impact of lifestyle choices on life expectancy. The discussion delves into acute vs. chronic risks, with practical examples such as the dangers of skydiving or how regular smoking affects longevity of life. The conversation also covers the application of statistics in medicine, the importance of randomisation in clinical trials, and the philosophical underpinnings of uncertainty. Additionally, David highlights the human capacity to judge risks, the pitfalls of intuition, and offers practical advice on dealing with uncertainty in everyday life. Lively anecdotes, insightful explanations, and practical takeaways make this episode a compelling listen for anyone interested in the intersection of statistics, risk, and daily decision-making.

David's latest book, The Art of Uncertainty is available in all good bookshops and online.
