Advice is important for decision making, especially in the financial sector. We investigate how individuals assess risk preferences of others given sociodemographic information or pictures. Both non-professionals and financial professionals participate in this artefactual field experiment.Subjects mainly rely on the other's self-assessment of risk preferences and on gender when forming the belief about someone else's risk preferences. On average, subjects consider themselves to be more risk-tolerant than the person they evaluate. Subjects use their own risk attitude as a reference point for predicting others' risk preferences. This false consensus effect is less pronounced for young professionals than for senior and non-professionals. Furthermore, financial professionals predict risk preferences more accurately compared to non-professionals.Classification: Risk Preferences, Financial Advice, Artefactual Field Experiment, Behavioral Finance JEL-Codes: C91, D81, G02 * We would like to thank Bodo Aretz, Alessandra Donini, Sarah Necker, Andreas Roider, Wendelin Schnedler and Andrew Schotter for their valuable comments and suggestions.
