Lecture, Presentation
Heuristics and Biases
- The presentation will demonstrate that perceiving optical illusions as their true state is perceptually impossible, even after understanding the concept of "heuristics and biases."
- System One is characterized as fast, parallel, automatic, and effortless, while System Two is described as slow; the modern world is predicted to be optimized in ways that make System One appear ineffective, particularly in finance.
- Real-world application of these concepts will include a discussion of the Israeli court system's parole grant data, with the expectation that judges will adjust behavior based on findings.
- The speaker intends to discuss the book Nudge by Cass Sunstein later in the session, potentially around the 90th minute.
- Kahneman's Nobel Prize lecture is planned as a source for analogies, with the speaker noting the award likely occurred in the 1990s or early 2000s.
- Framing effects will be illustrated using cancer treatment data (survival vs. death), predicting that audiences focus on longer-term survival rates under survival framing but earlier timeline parts under death framing.
- Anchoring bias will be demonstrated through experiments where random wheel numbers or "crazy anchors" (e.g., Martin Luther King's birth year before 500 BC) materially pull participant estimates.
- Marketing tactics such as lowballing and car sales "jujitsu" (refusing to counter-offer) are expected to be cited as natural cases where anchoring is utilized.
- Prospect Theory is predicted to explain why individuals are loss-averse and excessively irrational, often selling winning stocks too early and holding losing stocks too long despite utility theory suggesting indifference.
- Overconfidence is expected to manifest as 90% confidence intervals being correct only 50–60% of the time, with experts' self-belief rising faster than actual knowledge.
- Disagreements between smart individuals with equal knowledge are predicted to fail to converge, as people are systematically unwilling to account for the other party's intelligence.
- Confirmation bias is defined as the tendency to seek agreement-boosting information, illustrated by a speed of light graph where error bars shrank around an incorrect value.
- Heuristics and biases are not expected to be "fixed" but must be learned to control, with dancing and chess provided as examples of skills requiring practice to override System One.
- "Time masters" in chess are predicted to overcome the sunk cost fallacy by mentally treating past moves as "gone."
- Psychological experiments show that listing reasons for choices can reduce satisfaction compared to gut decisions, suggesting people fool themselves by amassing logical evidence.
- A "meta decision" on the reasonableness of relying on gut instinct is intended as advice for navigating specific decision-making areas.
