5W Launches the Hallucination Index — a New Brand-Safety Framework for the AI Answer Economy
5W has launched the Hallucination Index, the first public framework in U.S. communications research to standardize the measurement of AI-generated misinformation about real brands. The index measures accuracy, drift, and brand hallucination risk. The pilot covers fashion, with future indexes planned for pharmaceuticals, financial services, automotive, hospitality, and food and beverage. This initiative addresses a critical need for brand-side risk measurement in an era where AI-generated falsehoods can cause significant damage. The methodology suggests remediation through structured authority and highlights legal and procurement questions surrounding AI-generated consumer harm.
