Overview
- The study led by Professor John Nezlek and published in PLOS One surveyed over 3,500 adults in the US and Poland, including around 800 vegetarians.
- Vegetarians scored higher on values linked to power, personal ambition and social status, indicating a stronger desire for control over people and resources.
- Meat eaters were more inclined to prize benevolence, security, conformity and tradition than their vegetarian counterparts.
- Psychologists characterized the average gap in values between the two dietary groups as small to moderate yet statistically significant across the large sample.
- Researchers suggest these value differences may arise from the psychological toughness required of a dietary minority and say further studies may clarify whether such values drive or follow vegetarianism.
