Conjunction Bias
People mistakenly think specific combinations of events are more likely than general ones.
Why it works
First demonstrated by Tversky & Kahneman (1983), detailed scenarios feel more plausible than simple ones because they match mental models better. People confuse representativeness with probability, making specific stories seem more likely than general categories. This occurs because vivid details enhance processing fluency (Shafir et al., 1993).

Implementation tips
- Create detailed, specific customer scenarios rather than general benefit claims
- A/B test specific stories vs generic testimonials - specific often performs better
- Use realistic, relatable details that your audience can identify with
- Include multiple specific scenarios to cover different customer types
- Ensure scenarios are truthful and representative of actual customer experiences
- Use visual storytelling to make scenarios even more compelling
eCommerce fit
Medium Effective for complex products where specific use cases help customers understand value, but requires careful balance between compelling scenarios and realistic expectations.
Caution
Ensure specific scenarios are genuinely representative of typical customer experiences, not cherry-picked outliers. Don't create unrealistic expectations by presenting exceptional cases as normal. Be transparent about what outcomes customers can typically expect.
