Why Smart People Make Dumb Decisions
Introduction
- Exploration of why intelligent individuals sometimes make poor decisions or believe in conspiracy theories.
- Cognition isn't just logical processing; involves knowing, remembering, understanding, and communicating.
- Human cognition can lead to both brilliance and irrational thinking.
Cognition and Concepts
- Concepts: Mental groupings of similar objects, people, ideas, or events that simplify thinking.
- Without concepts, communication and understanding would be extremely laborious.
- Prototypes: Mental images or pinnacle examples of a certain thing.
- Example: 'Bird' prototype is more likely a robin than a penguin.
Problem Solving
- Humans use various strategies to solve problems:
- Trial and Error: Trying solutions until something works. Slow but thorough.
- Algorithms: Logical, step-by-step procedures that guarantee a solution.
- Heuristics: Mental shortcuts that speed up problem-solving but are error-prone.
- Insight: Sudden realization or 'Aha!' moments that lead to solutions.
Cognitive Bias and Errors
- Confirmation Bias: Favoring evidence that supports our beliefs and ignoring contradictory evidence.
- Overconfidence: Being more confident than correct.
- Belief Perseverance: Clinging to one’s beliefs even in the face of contradictory evidence.
- Functional Fixedness: Inability to see a problem from a new perspective.
- Mental Set: Predisposition to approach problems in a certain way.
Heuristics and Decision Making
- Availability Heuristic: Believing something is more likely because it is more memorable or vivid.
- Example: Casino wins are made highly memorable to entice further gambling.
- Memories and impressions of people can be shaped by vivid examples, leading to inaccurate judgments.
Fear and Perception
- We often fear the wrong things based on memorable but rare events (e.g., plane crashes vs. car accidents).
Framing Effect
- How an issue is presented can alter perception (e.g., survival rates vs. death rates).
Conclusion
- Our cognitive abilities are powerful but can lead to simple errors.
- Understanding our cognitive limitations can help improve decision-making.
Key Takeaways
- Use concepts and prototypes to ease thinking and communication.
- Apply algorithms, heuristics, and insight for effective problem-solving.
- Be aware of cognitive biases such as fixation, availability heuristic, and overconfidence.
