Thinking, Fast and Slow

Thinking, Fast and Slow is the groundbreaking work by Nobel Prize-winning psychologist Daniel Kahneman, offering a comprehensive tour of the mind and its two distinct systems of thought. Published in 2011, this bestselling book explores the dual processes that drive the way we think:

• System 1: Fast, automatic, intuitive, and emotional.

• System 2: Slow, deliberate, effortful, and logical.

Drawing from decades of pioneering research—including his influential collaboration with Amos Tversky—Kahneman uncovers how these systems shape our judgments, influence decision-making, and often lead us astray. From loss aversion and cognitive biases to framing effects and the illusion of understanding, the book sheds light on why humans frequently overestimate their rationality and underestimate the unconscious forces guiding their behavior.

With clarity and precision, Kahneman explains complex psychological concepts, such as prospect theory, anchoring, and substitution, making them accessible to both professionals and general readers. The book also explores practical applications of behavioral science in areas such as economics, medicine, business, and public policy.

Co-researched and co-written with contributions from Wall Street Journal columnist Jason Zweig, Thinking, Fast and Slow is more than a psychology classic—it’s a transformative guide to understanding human thought, decision-making, and the limits of intuition.
