What is going on inside their head? Why do some people think so differently to me? Why do I think what I think?

Bringing together startling new evidence from psychology, philosophy, sociology and political science, Marius Ostrowski breaks down our thinking into ten 'thinker-types' that help us understand ourselves and everyone around us.

We all fall within one or more of these ten distinct mindsets, from the 'Keen Bean' to the 'Agoniser', from the 'Happy Camper' to the 'Worrywart', as coined by Ostrowski. Some overlap, others clash. They are neither 'good' nor 'bad', and they are constantly evolving, adapting to our circumstances. We start growing into them from the moment we are born; which thinker-type we are is the result of our experiences over the course of our lives. Understanding where we and others fit within the ten 'thinker-types' is 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 an eye-opening tour of the mind and the surprising factors that shape not just what we think but how we think. It is the essential thinking about thinking.©2026 Marius Ostrowski
