  • Experimental
    Easy list of healthy habits

    In this condition, participants will be prompted to think about a list of healthy behaviors and check off (privately - they will never send this flyer back or show it to anyone) whether "yes" they conform to the healthy habit or "no" they do not. The list of healthy behaviors is a list that most people will find fairly easy, and thus most participants will answer "yes" to each habit. The final question will be a prompt to get a flu shot. The hope is that when people realize how healthy their habits are, it will seem natural to them to engage in yet another healthy habit and receive a flu shot.

    Challenging list of healthy habits

    In this condition, participants will be prompted to think about a list of healthy behaviors and check off (privately - they will never send this flyer back or show it to anyone) whether "yes" they conform to the healthy habit or "no" they do not. The list of healthy behaviors is a list that most people will find fairly difficult, and thus most participants will answer "no" to each habit. The final question will be a prompt to get a flu shot. The hope is that when people realize how unhealthy their habits are, it will seem wise to engage in one healthy habit that is easy (to make up for other bad behaviors) and receive a flu shot.
