The definitive work on diversity of thinking and inclusive leadership, Which Two Heads Are Better Than One? provides a proven formula.

Blending cutting-edge research and highly practical tips, Juliet Bourke challenges mainstream assumptions about diversity of thinking, and delivers a comprehensive framework to help ensure boards and executive teams see scenarios broadly, discuss options thoroughly, mitigate biases effectively and operate inclusively.

This new edition is a must-read for any leader looking to create genuinely diverse thinking groups, and packed with contemporary case studies ranging from the response to the COVID-19 pandemic in Asia to the Netflix $1million competition solution and the Volkswagen emissions scandal.

“After a decade or more of research telling us that diversity can deliver significant benefits, at last we have an evidence-based roadmap for how. I love this book.”
- Kate Jenkins, Australian Sex Discrimination Commissioner
“This is a book that distils complex behavioural theory into an accessible, engaging and important message. Juliet Bourke cites fascinating studies [and] shows how our decision making is riven with biases and process failures. Instead of just cautioning against the perils of such decision making, she sets out guidelines into the areas of inquiry that we might make – and proposes specific techniques for mitigating against unconscious bias and ways to enhance decision making.”
- Maxine Brenner, Non-Executive Director, Woolworths Group, Origin Energy, Qantas and Orica
“Diversity is too important to leave up to chance. Thankfully, Juliet Bourke provides us with a road map that helps us all, board directors and decision makers from across the sectors, achieve inclusive leadership where everyone can thrive and businesses perform at their best.”
- Professor Iris Bohnet, Harvard University, and author of “What Works: Gender Equality by Design”
“This is an excellent and much needed book. Juliet Bourke sets out to answer a major missing piece of the diversity debate so far - how do diverse teams create breakthrough ideas? She walks us through the answers step by step, making sure to leave no stone unturned. It is all very persuasive and itself a major breakthrough.”
- Frans Johansson, author of “The Medici Effect”
“Changing culture to build more inclusive workplaces is both essential and very difficult. Until now there have been no practical guides for leaders wanting to make a difference. This book changes that paradigm. Read it and prosper. I couldn’t put it down.”
- Professor Scott E. Page, University of Michigan
“Colliding clichés abound, ranging from ‘opposites attract’ to ‘birds of a feather’, speaking to inconsistent social biases but Juliet Bourke shows us systematically how to identify when such mental traps undermine fairness and clearheaded decision making. Which Two Heads Are Better Than One? transcends scolding about prejudice to reveal how diverse perspectives can break the decision-making pathology of group think. Excessive cohesion is actually the enemy of good teamwork and this book shows how diversity enhances constructive debate as well as enriches the portfolio of knowledge. Everyone from boards of directors to everyday work teams should snag this book!”
- Professor Jeffrey A. Sonnenfeld, Yale School of Management
“The topics of diversity and inclusion have been around for years. Juliet Bourke's book finally unlocks the secrets to making inclusion really happen, how to create diverse and inclusive teams, and how leaders can specifically behave to drive performance in an inclusive way.”
- Josh Bersin, Dean of the Josh Bersin Academy
“[This is] the best research-based book on understanding cognitive diversity that I have ever read (the breadth of the research and the ability to synthesize the disparate sources of data into a fully and articulate framework of applied cognitive diversity). There are books that are purely academic, or science based, or mostly comprised of anecdotes and metaphors – but this book takes the best of each approach and blends them into a most useful practical guide. This book is a game-changer!”
- Dr Bruce Stewart, past Deputy Director, Office of Diversity and Inclusion, “responsible for implementing President Obama’s Executive Order on Diversity and Inclusion across the federal government”
Juliet Bourke's book is both thought provoking and an essential tool for directors seeking to make good decisions and ensure better overall governance.”
- Melanie Willis FAICD, Independent Non-Executive Director
“Chairs have an opportunity to sponsor, lead and facilitate change to provide the environment and conditions to enable diverse thinking. I encourage all chairs and leaders to read Which Two Heads Are Better Than One?, [and to] think about the changes they can lead.”
- Vanessa Stoddart, Independent Director, New Zealand
