How cognitive biases shape decisions
Daniel Kahneman
Why do we make the decisions we do? Nobel Prize winner Daniel Kahneman revolutionised our understanding of human behaviour with Thinking, Fast and Slow. Distilling his life’s work, Kahneman showed that there are two ways we make choices: fast, intuitive thinking, and slow, rational thinking. His book reveals how our minds are tripped up by error, bias and prejudice (even when we think we are being logical) and gives practical techniques that enable us all to improve our decision-making. This profound exploration of the marvels and limitations of the human mind has had a lasting impact on how we see ourselves.
Review
Thinking, Fast and Slow is a brilliant deep dive into how our minds work, and how they often mislead us. Kahneman explains the two systems of thinking: System 1 (fast, intuitive) and System 2 (slow, analytical), showing how biases, shortcuts, and mental errors influence our decisions more than we realise. As someone in business strategy, I found this incredibly eye-opening. It’s helped me question assumptions, improve critical thinking, and approach data and decision-making more carefully.
The book isn’t light reading, but it’s packed with insights that apply to everything from marketing to management. If you want to understand human behaviour and make smarter decisions, both personally and professionally, this is one of the most important books you can read.
