The Cognitive Reflection Test (CRT) is a widely used measure of individual propensity to rely on analytic thinking. This measure is consistently related to decision-making tasks, beliefs and real-life decision outcomes and also inversely related to conformist and mindless decision making. Drawing from previous studies showing that food choices are related to cognitive style, we hypothesised that an analytic cognitive style would be inversely related to meat consumption and beliefs supporting meat eating. In two highly powered studies (total N = 7283), we investigated the relationship between the CRT and meat consumption and associated beliefs, controlling for relevant demographics. Our results showed that a higher CRT score predicted self-identification as vegetarian, exclusion of meat and fish from diet and lower belief that meat consumption is normal and necessary for health (study 1). This link remained when need for cognition and self-esteem were introduced as concurrent predictors (study 2). Despite a small observed effect size, these results confirm the relevance of the CRT for investigating consequential decision making and habits. •More analytic thinkers engage in less mindless decision making.•Meat eating represents a majority and default eating behaviour.•We investigated relationships between cognitive reflection and diet.•Higher score on Cognitive Reflection Test related to less pro-meat beliefs and behaviours.
