Dr Chengwei Liu on Luck & Serendipity

Have you ever wondered how much of your success is down to luck? What if the world is far less fair and predictable than we’d like to think?
 
On this episode, I explore the complex and fascinating role of luck in our lives and decisions with Dr. Chengwei Liu, Associate Professor of Strategy and Behavioural Science at Imperial College London. Chengwei shares how his research challenges our assumptions about skill, effort, and fairness – and why the outcomes we see are often far more random than we’d like to believe.
 
We discuss why many successful strategies and best practices are built on shaky ground, and how our tendency to downplay luck creates illusions of control and reinforces unfair systems. Chengwei explains how beliefs in fairness – like the ‘just world’ hypothesis – shape everything from business cultures to political systems, and how luck and misperceptions of it can create cycles of privilege or disadvantage.
 
Chengwei also shares practical insights on how to become a smart contrarian: someone who can harness the power of randomness and serendipity while avoiding the pitfalls of bias and overconfidence. From the dangers of blindly following the ‘successful’ to the need to look inward and embrace uniqueness, it’s a thought-provoking conversation that will change the way you think about risk, decision-making, and what it really means to get ahead.
 
Guest Biography
Dr. Chengwei Liu is an Associate Professor of Strategy and Behavioural Science at Imperial College London. He describes himself as someone fascinated by how luck, randomness, and human biases shape success and failure – both in business and in broader society.
 
Chengwei’s work challenges mainstream management thinking and explores how much of what we attribute to skill is actually the result of random factors. 

His book, Luck: A Key Idea for Business and Society, examines these dynamics and how we can learn to navigate them.
 
Beyond his academic roles, Chengwei has also worked as a management consultant, drawing on his experience in both research and practice to uncover how to harness luck and uncertainty.
