Nobody Knows What's Going On: The dumb human's guide to dumb humans
summary
A mattress buyer endures 1,400 days of pain before buying because showroom testing and sales pressure fail to reveal real barriers: inability to trial a bed with a partner, delivery and stair logistics, and slowly rising discomfort. Surveys and analytics miss these causes and introduce biases like asymmetric dominance (PowerPoint logo beating better designs). Effective research uses an unstructured → chronological → explicit sequence: open interviews, timeline probes, and props/concept cards to surface actionable motivations and design opportunities.
