Adherence
Educational documentaries can significantly increase intentions to reduce meat consumption, but these intentions do not predict actual consumption.
While watching a documentary might make you *want* to eat less meat, it won't necessarily make you *do* it. The study shows a significant increase in intentions, but no change in actual consumption. To make real changes, focus on practical, small-scale adjustments to your environment and habits rather than relying on informational interventions.
However, the documentary did substantially increase intentions to reduce consumption, consistent with past studies (Studies 2 and 3).
Why this rating
Randomized controlled trials with large sample sizes and rigorous blinding against social desirability bias.
