Why did France lose to the Nazis, despite its defenders having more tanks, troops and guns? How did Ukraine repel Russia’s initial onslaught? How do you know if you can trust an ally? How can we make clearer decisions under pressure?

In Warhead, Nicholas Wright takes us on a fascinating journey through the brain to show us why, if we want to understand warfare, we must first look inside our own heads. Drawing on his work as a neuroscientist and over a decade spent advising the Pentagon and the UK government, he reveals how, whether we like it or not, the brain is wired for conflict – in the office or on the battlefield.

With a unique framework that helps explain today’s rising tensions and how to defuse them, Warhead brings cutting-edge research to life through stories from across history. What was it like for a foot soldier at the Battle of Waterloo in 1815? How did Shaka Zulu or Winston Churchill see through the fog of conflict, make better decisions and communicate with their troops? How will human conflict shape our future technologies?
