## Thinking, Fast and Slow

You think you are reasoning. Most of the time you are rationalising something your gut decided first.

## Two Systems, One Mind

Daniel Kahneman's 2011 summary of decades of research with Amos Tversky introduces System 1 and System 2 thinking. System 1 operates automatically and quickly, full of biases and heuristics that evolved for survival but fail in modern complexity. System 2 is analytical and deliberate but effort-intensive and easily overridden. The book maps dozens of cognitive biases including anchoring, availability, loss aversion, and overconfidence, each one a window into the gap between how we think we think and how we actually do.

The Two Systems

Foundational

"A framework that immediately changes how you watch your own mind work."

> Nothing in life is as important as you think it is while you are thinking about it.

Kahneman was awarded the Nobel Prize in Economics in 2002 despite being a psychologist. He spent 40 years collaborating with Amos Tversky, who died in 1996 and could not share the prize. Kahneman said they thought as one mind.

The book became a global bestseller and reshaped business, medicine, public policy, and behavioural economics. It is cited in more fields than perhaps any other single popular science book published this century.
