Thinking, Fast and Slow — Daniel Kahneman (2011)

Thinking, Fast and Slow transforms decision-making by exposing the cognitive biases that distort every judgment, from loss aversion to the planning fallacy. Kahneman's research, which earned him a Nobel Prize, is backed by decades of experiments showing that humans rely on intuitive System 1 thinking 95% of the time, often leading to systematic errors. It demonstrates that understanding mental shortcuts like the availability heuristic can reduce financial mistakes by up to 30%, making it a data-led guide to smarter choices.
