Education is supposed to protect against conspiracy theories and misinformation. Critical thinking, evidence evaluation, logical reasoning—all the cognitive tools that come with formal education should inoculate people against obvious nonsense.

Except when it doesn't.

Researcher Tylor Cosgrove published findings in the Journal of Personality and Individual Differences that explain this paradox: narcissistic traits override the protective effects of education.

In a study of over 660 adults with education levels ranging from high school through doctoral degrees, Cosgrove found that narcissism predicted conspiracy theory acceptance regardless of educational attainment. When narcissistic traits were above average, "highly educated people were just as likely to endorse these beliefs as those without any formal education."

Let that sink in. A PhD and a high school dropout show identical susceptibility when narcissism is present.

The study examined three dimensions of narcissism:

1. Grandiosity—sense of superiority and entitlement 2. Need for uniqueness—desire to see oneself as distinct from others 3. Cognitive closure—preference for definitive answers over uncertainty

Here's the mechanism: education develops analytical skills, but humans are excellent at motivated reasoning—deploying those skills to reach preferred conclusions rather than objectively evaluating evidence.

When narcissistic individuals feel superior to experts, or need certainty during uncertain times, they use their reasoning abilities defensively. The analytical tools become weapons for maintaining unfounded beliefs rather than testing them.

It's the same cognitive machinery, running in reverse.

Cosgrove identifies the core problem: narcissistic individuals often distrust authority and expertise (because they view themselves as superior), which makes them receptive to alternative explanations that position them as possessing special knowledge that ordinary people lack.
