Important… an expert use of data with moving, personal storytelling. A key text for how we live now.

— David Baddiel

Utterly brilliant… powerful… From personal histories to broader social patterns, from individual criminal cases to the latest neuroscience and psychology, Matthew Williams’ forensic dissection of hate reveals its insidious power – but also its weaknesses. This book is not just about how and why hate happens – it’s about how to combat it. 

— Alice Roberts, broadcaster and author of Ancestors

This is an incredibly powerful, important and valuable book on what causes hate and how we can help prevent and defeat it. 

— Peter Tatchell

An absolutely tremendous book…a harrowing but illuminating work, being released at a time when hate appears to be on the ascendency but far from trying to stop it, some of the world’s most powerful people seem to be using it to manipulate millions . . . At times it reads more like a thriller. Fascinating.

— David Marsland ― Evening Standard

Amazing. Everything you could possibly want to know about hate. As someone who is not a criminologist, I can say it is completely gripping, readable, fascinating and very accessible. Full of insight and new information. Essential reading for anyone who’s interested in crime and its causes. I strongly recommend it. 

–Sophie Hannah, bestselling crime novelist and author of the new Hercule Poirot mysteries

Perceptive, authoritative and above all a convincing analysis of the complex mechanics of hatred. Hatred is a frightening phenomenon, but understanding how it works, and why, must surely be the first step in understanding how to deal with it. 

— Andrew Taylor, bestselling author of The Last Protector

Moving… fascinating… meticulously researched… written in a really accessible manner… expansive in approach and supplemented with so many real-world case studies. This is a really key contribution to our understanding of the divides in our society, and how these can perhaps be repaired.

— Pragya Agarwal, author of Sway: Unravelling Unconscious Bias

Fascinating and beautifully written. I heartily recommend it.

— Hugo Rifkind ― The Times & Times Radio

An extraordinary book.

— Connie McLaughlin ― BBC Radio Scotland

Williams is masterful at making this complex topic accessible, so we can all better understand hate and the dark side of human behaviour and finally, start to tackle it.

— Nova Reid, author of The Good Ally

The Science of Hate is excellent. I can’t recommend it enough. It’s an indispensable guide to what’s gone wrong…throughout much of the Western world. If you want to know why the world is a bear pit read it.

— Neil Mackay ― The Herald

Insightful. Accessible. Illuminating. Thought provoking. . . A forensic, unflinching and comprehensive enquiry into hate that also manages to be humane, generous and constructive. A great invitation for us to view ourselves ‘in the round’.

— Caryl Lewis ― author and lead writer on BBC/S4C’s HIDDEN

This sometimes harrowing but very necessary book couldn’t be more topical, but what gives it even greater impact is the fact that the author has himself been the victim of hate crime. 

— Caroline Sanderson ― The Bookseller (Editor’s Choice)

An accessible and beautifully researched book about the social, psychological and cultural conditions which drive people to hate, but also an invaluable toolkit that should  be employed to eradicate hate from our communities.

 — Professor David Wilson, author of A Plot to Kill and My Life with Murderers

Professor Williams’ expert analysis has been fundamental to several high-profile prime time TV documentaries on the rise of hate crime and speech. He has the unique ability to translate highly complex science into meaningful, accessible and impactful journalism that a mass audience can easily comprehend. 

— Mark Alden, producer and director of Hate on the Streets (BBC Panorama) and Brexit Online Uncovered (ITV Exposure)

Professor Matthew Williams is one of the most noted scholars of cyber-hate in the world and has a particular gift for rendering complex analysis comprehensible. His interest in hate crime is long standing and it has been his passion to communicate his own deep understanding of the subject to a general audience.
