Cognitive Biases and the User Experience
summary
Overview of specific biases with concrete takeaways: documents A/B test with 10 users as underpowered and shows how confirmation bias and illusory correlation can mislead, cites the IKEA effect paper showing labor raises valuation, references an Israeli penalty‑kick study of 200+ kicks to illustrate action bias. Advises using varied user samples, watch behavior instead of asking leading questions, remove brand during testing, treat NPS cautiously, timebox reviews to avoid bike‑shed discussions, and validate correlations before claiming causation.
