Thinking, Fast and Slow
Fast intuition, limited attention, biased judgment, and loss-sensitive choices explain why confidence often exceeds accuracy.
Fast thinking is automatic and associative; slower thinking requires attention and effort. These are explanatory process labels, not separate organs. The slower process often accepts an intuitive answer instead of independently checking it.
A smooth explanation can feel right before we check it. Kahneman makes that ease visible: the mind often supplies a coherent answer faster than it establishes whether the answer deserves confidence.
People substitute easier questions for difficult ones. Availability, anchors, representativeness, and framing can distort estimates, especially when base rates and sample size are neglected.
Overconfidence grows from coherent stories built from incomplete information. Forecasts often underweight outside evidence, while success encourages explanations that make uncertain outcomes appear predictable afterward.
Prospect theory describes choices relative to reference points: losses often matter more than comparable gains, and the presentation of risk changes decisions. Experienced wellbeing also differs from how an experience is remembered.
Improved decisions rely on procedures and environments, not merely awareness of bias. Some individual examples, especially from social-priming research, have faced replication challenges and are not universal laws.
The practical difficulty is not that intuition is always bad. It is knowing when an environment has taught it reliably, and when a structured comparison would reveal what confidence hides.
Cognitive ease can be mistaken for familiarity, reliability, or truth.
Small samples can produce patterns that invite overconfident causal stories.
Loss-sensitive choices change when equivalent options are framed differently.
The remembering self can evaluate an experience differently from lived moments.
Skilled intuition needs environments with dependable patterns and useful feedback.
