 Episode notes 
Pepsi Challenge Triggered New Coke
- Pepsi Challenge blind tests suggested more people preferred Pepsi over Coca-Cola.
- Coca-Cola panicked and reformulated its recipe based on those results.
Test Products In Real Contexts
- Avoid predicting consumption from single sips or de-branded taste tests.
- Try experiments with full packaging and natural drinking contexts instead.
Observe Behavior, Not Verbal Reports
- Do observe actual purchasing behaviour instead of relying on taste-question research.
- Do run simple field A-B tests and watch choices in context rather than asking people hypothetical questions.
