Barnum Effect

Broad, high-base-rate statements can feel uniquely accurate when they are presented as a personal assessment.

+

Design strengthRecognising the effect helps teams audit personality quizzes, AI-generated insights and health, career or financial recommendations for false specificity. It encourages products to show what information genuinely changed an output and how uncertain or widely applicable each statement is.

Use with careExploiting broad flattering feedback can create unwarranted trust, disclosure, purchases or consequential decisions. Satisfaction, recognition or engagement does not validate an assessment, while dismissing every broadly useful statement as Barnum can also overlook genuine evidence and shared needs.
