Detaljeret beskrivelse
Participants will complete a within-subjects, randomized experiment in which they view and rate messages describing deceptive marketing tactics used by food companies to sell unhealthy 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 consuming unhealthy products, (4) targeting groups, (5) piggybacking on social causes to promote products. Each topic is presented in five framing variants: an unframed version and four values-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 × 5 framing variants, plus 1 control).
Topic order is randomized across participants; within each topic, the five framing variants are presented consecutively in random order.

Participants also view one control message, for a total of 26 messages (5 topics × 5 framing variants, plus 1 control). Topic order is randomized across participants; within each topic, the five framing variants are presented consecutively in random order. |
