Practical Examples

1. Loss Aversion in the NBA Draft

   The book describes how NBA teams tend to keep players they've invested in, even when they've proven to be ineffective, because admitting a 'bad draft pick' feels like a loss. This is a direct result of loss aversion bias, where the pain of losing is much greater than the pleasure of gaining, leading to irrational decisions.

2. Diagnosis Bias in Medical Care

   An account is given of how doctors and nurses sometimes stick with an initial diagnosis even when new evidence emerges, causing misdiagnosis. The original label sways their perception, highlighting how diagnosis bias can have serious real-world consequences.

3. Impact of Group Dynamics on Shuttle Challenger Disaster

   The authors detail how NASA engineers, despite concerns, went along with group consensus before the disastrous Challenger launch. Groupthink suppressed dissenting voices, illustrating how strong social conformity can override sound judgment.

4. Commitment Escalation in Business

   Executives sometimes throw more resources into failing projects, refusing to admit mistakes due to sunk cost fallacy. The narrative shows how the drive to justify prior decisions can result in greater and greater irrationality.

5. The Power of Labels in Education

   One study described in the book found that students who were labeled as 'gifted' performed better academically than their peers, regardless of actual ability. This demonstrates how labels create self-fulfilling prophecies that sway outcomes.

6. Fare Pricing and Airline Ticket Sales

   Airlines noticed that when people see a higher 'original price' next to a discounted fare, they're far more likely to buy—showing how framing sways financial decisions irrespective of objective value.

7. Jury Decisions and First Impressions

   Courtroom studies revealed that the first impression of a defendant sways jurors’ opinions, making it much harder for subsequent facts to counteract an initial bias.
