Adherence
Educational documentaries can significantly increase intentions to reduce meat consumption, but these increased intentions do not translate into reduced actual consumption.
You can watch a documentary and genuinely *want* to eat less meat, but that desire alone won't change your diet. The study shows that while intentions go up, actual eating habits stay the same. To bridge this gap, you need more than just motivation; you need a plan, recipes, and environmental support to turn that intention into action.
However, the documentary did substantially increase intentions to reduce consumption, consistent with past studies (Studies 2 and 3).
Why this rating
Supported by multiple studies (2 and 3) with consistent results on intention.
