Thinking, Fast and Slow

Main Ideas

• The human brain operates in two modes: fast, intuitive, emotional (System 1) and slow, logical, critical (System 2).
• System 1 works automatically and quickly, with little or no effort and no sense of voluntary control, while System 2 requires attention and effort, engaging in complex computations.
• People tend to be overly confident in their intuitive judgments and underestimate the likelihood of events, leading to systematic errors in decision-making.
• The availability heuristic affects our choices and judgments when we exaggerate the probability and significance of events that are easily recalled.
• Prospect theory shows that people evaluate losses and gains differently, with losses feeling more significant than equivalent gains ('losses hurt twice as much as gains please').
• Heuristics and biases in decision-making play a significant role in how people make choices and judge the probability of events.
• The 'status quo' and 'loss aversion' demonstrate that people have a strong tendency to avoid risks when the possibility of losses is present.
