As a statistician by trade, Cambridge University Emeritus Professor, Sir David Spiegelhalter might seem to be a huge outlier for our leadership podcast. At the beginning of our conversation he even acknowledges feeling this way.

But his new book, The Art of Uncertainty, was named an Amazon Best Book of 2025, and his investigations aimed at reducing uncertainty in life: about what is happening, what might happen – even why things have happened – have yielded some remarkably useful insights on how leaders can most effectively navigate complex situations. And it’s absolutely invaluable knowledge these days.  

As you’ll soon realize on your own, our conversation reveals not only his brilliance, but that he’s also a keen observer of what drives leadership success. It’s also no surprise that that his 50 years of work is so impressive that Queen Elizabeth Knighted him.

With clear, engaging and truly charming delivery, Sir David explains why leaders often fear the unknown and how accepting it fosters resilience. He challenges the instinct to eliminate uncertainty, highlighting humility and adaptability as key to success. He also redefines “luck” – not as something mystical but as a skill – built through openness to opportunities and perseverance. His point is we can learn to make ourselves more lucky in life – a wiser path than hoping the universe bestows it upon us.

Before we’re done, we discuss the importance of balancing intuition with data when making important leadership decisions (currently a wildly uncommon practice in business) along with real-world examples of leaders who’ve succeeded by routinely questioning assumptions. Finally, Sir David shares a brilliant model leaders can use to communicate in uncertain times when they do not have the all the answers – and also don’t want to appear indecisive.

We believe there is great wisdom to be gained from experts outside of business and workplace leadership. And one of the world’s truly great analytical minds (a statistician!) proves the point in this wonderful conversation.
