The Art of Thinking Clearly by Rolf Dobelli is an entry level, very accessible introduction to cognitive biases and common errors in judgement. Unlike more demanding and analytical works such as Kahneman’s Thinking, Fast and Slow, Dobelli’s book is written in short, clear chapters and can be read almost as a practical handbook. It does not simplify the ideas too much, but makes them easier to remember and to use in everyday managerial and strategic thinking. It is a good starting point for anyone who wants to become more aware of how their mind quietly misleads them.
