Combating Memory Limitations Through Simultaneous Triangulation
summary
Argues that memory gaps bias interview data and shows a reproducible fix: run simultaneous triangulation by pairing a three‑week diary study of 40 Spotify Free listeners with a daily data dashboard that tracks listens, ads and skips. Finds users form false mental models (one user thinks ad skips are capped at six), surfaces format differences (skippable vs unskippable video ads), and enables targeted PSA messages. The intervention doubles feature usage in the test, demonstrating the method uncovers actionable behavior that memory alone misses.
