Penguin How Spiies Think: Ten Lessons in Intelligence

Learn from the former director of GCHQ the methodology British intelligence agencies use to reach judgments, establish the right level of confidence, and act decisively.

Intelligence officers discern the truth. They gather information - often contradictory or incomplete - and, with it, they build the most accurate possible image of the world. With the stakes at their absolute highest, they must then decide what to do.

In everyday life, you face contradictory, incomplete information, too. Whether you're reading the news on social media, figuring out the next step in your career, or trying to determine whether gossip about a friend is true, you are building an image of the world and making decisions about it.

Through the eyes of one of Britain's most senior ex-intelligence officers, Professor Sir David Omand, How Spies Think shows how you can make big decisions in your life more easily by applying the same frameworks used by British intelligence. Full of revealing examples from his storied career, including key briefings with Prime Ministers from Thatcher to Blair, and conflicts from the Falklands to Afghanistan, Professor Omand arms us with the tools to sort fact from fiction and shows us how to use real intelligence every day.
