The psychology behind irrational decisions - Sara Garofalo
Summary
TLDRThe video explores cognitive biases, particularly loss aversion, which affects decision-making. It explains how people often prefer guaranteed outcomes to risks in situations where losses are possible, even when the odds are identical. The script also discusses how heuristics, mental shortcuts based on intuition, can lead to irrational choices, such as the conjunction fallacy and the anchoring effect. While heuristics evolved to help humans make quick decisions, they can be misleading in complex situations involving probability, numbers, or multiple details. Awareness of these biases can help make better, more rational decisions.
Takeaways

- 🎲 People tend to misjudge probabilities, as shown in the conjunction fallacy, where less likely options are chosen based on faulty expectations.
- 🚫 Heuristics are particularly poor when dealing with numbers, leading to errors like the anchoring effect.
- 🛒 The anchoring effect is commonly used in marketing, influencing people’s willingness to pay higher prices.

- 🔍 While we can't eliminate heuristics, being aware of them can help us avoid flawed decision-making, especially when numbers and probabilities are involved.
