I want respondents to see a scenario (common scenario that contain uncivilized behavior of consumers) and then provide vignette carrying a message (manipulative variables-Proscriptive Vs Prescriptive Message) and then check respondents willingness to take action.

How to design this study?

How to design this study while not caught up with ethics board as I intend to include negative scenario (common scenario). Reason is that common message can trigger negative emotions of participants.

Appreciate quick response.
