Meta-analysis of personality trait differences between omnivores, vegetarians, and vegans
In the West, there has been a rise in the consumption of vegetarian and vegan food. Due in part to the fact that personality traits are broad characteristics that can combine information about several elements that inspire vegetarian or vegan diets, recent research has concentrated on personality trait disparities between dietary groups. However, prior studies on the personality determinants of vegetarian and vegan (veg*n) diets have produced mixed findings. This meta-analysis by Reist et al. (2023) sought to reconcile previous research findings on differences between the Big Five personality characteristics in omnivores and vegetarians and vegans, as well as between veg*ns and omnivores. Data from 15 publications (total n = 69,576) was included. The findings showed that whereas vegans were significantly higher in Openness than vegetarians, veg*ns were significantly higher in Agreeableness and Openness than omnivores. In addition to laying the groundwork for future research on the factors that drive vegetarian or vegan diets, the authors highlight that this work isolates Openness and Agreeableness as significant trait predictors of plant-based diets. In addition to being able to predict the sources, courses, and correlates of dietary choices, personality traits can offer an integrated framework for conceptualizing dietary preferences. They may also be helpful for activists and legislators who are trying to customize meat-reduction initiatives. [NPID: Big five, meta analysis, personality, traits, vegan, vegetarian]
