Beliefism : How to stop hating the people we disagree with

''Brilliant, wise, humane, scientific, and kind. Beliefism is exactly what the doctor ordered - and it could change the world'' Cass R. Sunstein, Robert Walmsley University Professor, Harvard University

"Repeated throughout is the fine principle that whatever position you wish to argue on an issue, you must be honest about what bad effects, as well as good, will follow." Steven Poole, The Times

Beliefism (noun): Discrimination against people who disagree with us

Do you avoid people who are strongly against immigration? Or strongly for trans rights? Against abortion? For drug legalisation? We might like to think that we''re tolerant, but many of us struggle to engage with people whose opinions differ strongly from our own-even if they might have something useful to contribute to the debate. That means we''re falling victim to what behavioural scientist Professor Paul Dolan defines as Beliefism: discrimination against those with different beliefs to us.

Drawing on the evidence from across the social sciences, Dolan shows how easy it is for us to divide ourselves into opposing camps - and how harmful that can be. Using the central metaphor of the duck-rabbit illusion-where the same image can be viewed as one animal or the other-the book shows that looking at an issue from only one perspective can lead to bad decisions and unnecessary conflict. The world would be a better place if there was less beliefism and Dolan shows how more tolerance is only possible "by design". We need to embed less beliefism into our organisations and lives and he provides a checklist called EMBRACE to help us do that.

Combining curiosity, irreverence and warmth, Beliefism is a definitive behavioural science take by a leader in his field. Whether it''s among friends, at university or at work, being less beliefist will make you a better partner or parent, and a more effective buddy or boss.
