Thinking Aloud: The #1 Usability Tool

Jakob Nielsen · Nielsen Norman Group Free Beginner

This is the technique that turns watching into understanding. Ask users to narrate their thoughts while they work, and their confusion, wrong guesses, and moments of relief become audible. Nielsen argues it is the cheapest and most valuable method you have, and this piece is a quick guide to doing it well.

  • Their wrong guesses point straight at unclear labels and flows
  • It is cheap, flexible, and needs no special equipment
