Main Topic

“Thinking, Fast and Slow” by Daniel Kahneman explores the two modes of thinking that drive human decision-making: System 1 (fast, intuitive, and automatic) and System 2 (slow, deliberate, and analytical).

  • Availability Heuristic: The book explores how people assess the likelihood of events based on their availability in memory.
