Do you consider animal welfare to be important? activating cognitive dissonance via value activation can promote vegetarian choices

Reducing global meat consumption can improve animal welfare, environmental and health issues. Although many people recognize this, they also continue eating meat. When people become aware of their conflicting cognitions regarding meat consumption, such as finding both animal welfare and eating meat important, it can result in aversive feelings, known as cognitive dissonance. We add to the literature by exploring whether cognitive dissonance can be used to support desired behavioral choices. More specifically, we examine whether activating peoples' pre-existing animal welfare values, by stimulating them to reflect on whether they consider animal welfare to be important, can trigger cognitive dissonance and in turn promote the choice for vegetarian meals. An online study showed that our value activation strategy indeed increased the amount of cognitive dissonance people experience when thinking of consuming meat, which in turn increased their intention to eat a vegetarian meal, especially among those with a strong pro-environmental self-identity. A subsequent field study in a restaurant showed that our value activation strategy (almost) doubled the percentage of vegetarian burgers ordered. Our findings show that stimulating people to reflect on whether they consider animal welfare to be important can force people to face their inner conflict regarding meat consumption and channel that into choosing a vegetarian meal.

Automated summary

Stimulating people to reflect on the importance of animal welfare can trigger cognitive dissonance and promote the choice for vegetarian meals. The findings of the online and field studies in this research show that activating animal welfare values increases the level of cognitive dissonance people experience regarding meat consumption, leading to a higher intention to eat vegetarian meals.
