We are becoming more and more divided in how we see the world. Why is it some people think so differently to the way others do? Bringing together for the first time startling new evidence from neurobiology, psychology, philosophy, behavioural economics and more, Marius Ostrowski takes us on an eye-opening tour of the mind and the surprising factors that shape not just what we think but how we think. Ostrowski breaks down the different elements of our thinking into ten 'thinker-types' that help us understand ourselves and everyone around us. These ten distinct mindsets, from the 'hot-head' to the 'improviser', coined by Ostrowski, are profiles we all fall within. Some overlap, others clash. They are neither 'good' nor 'bad', but understanding where we and others fit can be transformative. Through these ten ways of thinking, Ostrowski gives us remarkable insight into our own minds as well as those who think differently to us, and reveals how we might even change our minds for the better. How We Think is the essential thinking about thinking.
