## Description

In Practical Thinking de Bono’s theme is everyday thinking, how the mind actually works – not how philosophers think it should . Based on the results of his famous Black Cylinder Experiment (a critical thinking task that asks participants why they think a black cylinder falls over), de Bono explores the four practical ways of being right. From there he picks out and names the five levels of understanding – and the five major mistakes in thinking. From memes and Instagram to twitter and bestselling books like Mistakes I Made At Work , mistakes – and what we can learn from them – are a hot topic. With Edward you’ll learn exactly why we all make them.
