Young Adult Food Messaging Experiment

Participants will complete a within‐subjects, randomized experiment in which they viewand rate messages describing deceptive marketing tactics used by food companies to sellunhealthy products.Messages cover five topics: (1) lying about unhealthy products being healthy, (2)engineering foods to be addictive, (3) covering up evidence about the harms of consumingunhealthy products, (4) targeting groups, (5) piggybacking on social causes to promoteproducts. Each topic is presented in five framing variants: an unframed version and fourvalues‐based frames that connect the message to a value (e.g., authenticity, fairness).Participants also view one control message, for a total of 26 messages (5 topics × 5framing variants, plus 1 control).Topic order is randomized across participants; within each topic, the five framingvariants are presented consecutively in random order.
