Abstract
Climate change is a serious threat to the planet and to humans. Additionally, plant-based proteins are considerably more environment-friendly than meat. Vegans and vegetarians (veg*ans) are a minority but we need them to stand-up and spread awareness for these kinds of diets so they influence other people to adopt them as well, helping mitigate climate change. The present study proposed that self-esteem and moral convictions, separately, explained speaking-up and going against the norm, and that moral convictions would be more strongly related with that behavior. The dependent variable standing-up was represented by the signing of a petition that was known to have none or small signatories, implying that signing it would mean adopting a minority position. There were two studies conducted: Study 1 was in the lab and was based on the study by Bolderdijk & Cornelissen (2022) but it was unsuccessful due to a small sample size and the fact that all participants signed the petition, not allowing the performance of statistical analyzes. Study 2 was a replication of the first, but online. This study did not have significant statistical results, thus none of our hypotheses relating self-esteem and moral convictions with advocacy behaviors was supported. However, an important finding was that nearly every participant signed the petition, showing that they were willing to stand-by their moral beliefs. In sum, it could be easier than we predicted to find, for example, spokespersons that are willing to spread the idea and benefits of plant-based diets. Keywords: self-esteem, moral convictions, speak-up, veg*ans, (non)conformity
