What someone tells you can reshape the choices you make — even choices that feel personal. In this taste test, at least 30 participants split into three groups. Group A tastes and picks freely, relying entirely on their own senses. Group B hears that one brand scored highest in a consumer report before tasting. Group C gets the same expert tip but must also justify their final decision in writing. Comparing results across all three groups shows whether an expert opinion, or simply the need to explain a choice, pushes people away from what their own taste buds tell them.
