What is the best way to think about the world? How often do we consider how our own thinking might impact the way we approach our daily decisions? Could it help or hinder our relationships, our careers, or even our health? Thinking about thinking is something we rarely do, yet it is something science questions all the time. David Sumpter has spent decades studying what we could all learn from the mindsets of scientists, and Four Ways of Thinking is the result. Here he reveals the four easily applied approaches to our problems: statistical, interactive, chaotic and complex.

"What should we have for dinner?" To one degree or another, this simple question assails any creature faced with a wide choice of things to eat. Anthropologists call it the omnivore's dilemma.

On 25 May 1982, at a critical juncture in the Falklands War, the destroyer HMS Coventry was attacked by Argentinean aircraft. In a devastating strike, she was hit by three bombs, two of which exploded inside her hull, killing 19 of her crew and leaving many others badly injured. Within minutes Coventry had capsized, and would finally sink the following day. It was the first occasion since the Second World War that a British captain and crew had to abandon a stricken ship.
