# New Psychology Research Challenges Conspiracy Mentality Theory Large-scale study finds no single pattern linking general conspiracy mindsets to specific beliefs. - **Source:** [PsyPost](https://www.psypost.org) - **Published:** 2026-11-07 - **Topic:** [science](https://brifing.si/c/science) - **Original article:** - **On Brifing:** https://brifing.si/s/eb5db75b-3150-46f9-a6a8-9d7602bfc8bc ## Challenging the Mentality Hypothesis Psychologists traditionally argue that a broad conspiracy mentality acts as a stable personality trait, driving individuals toward specific conspiracy beliefs. However, a new large-scale analysis involving nearly 30,000 participants across 17 countries suggests this overarching mindset does not consistently sit at the center of people's conspiracy belief systems as previously assumed. ## Defining Conspiratorial Thinking Researchers distinguish between specific conspiracy beliefs, which target concrete claims about events like terrorist attacks, and conspiracy mentality, a generalized worldview of suspicion toward authorities. While people rarely hold just one theory in isolation, the causal link between a general suspicious mindset and specific, unrelated conspiracy claims remains statistically debated. ## Network Psychometrics Approach The research team utilized network psychometrics to map how survey responses relate to one another without assuming a single hidden trait causes them. By using exploratory graph analysis and partial correlation networks, they tested whether a combined mentality score functioned as the most connected hub within a web of specific beliefs. ## Study One Findings Analyzing data from eight Western democracies, including the United States and Italy, researchers found that general mentality and specific beliefs formed two distinct dimensions. In seven of these countries, the mentality-centered model was formally falsified, indicating that a general mindset did not explain the clustering of specific conspiracy theories among the participants. ## Contextual Variations in Results Study two, focusing on politically prominent American conspiracy theories, leaned toward the mentality-centered account, showing the general mentality score as a strong hub. This contrast with the first study suggests that highly salient, context-bound theories may overlap more closely with generalized suspicions than broader, cross-national batteries of conspiracy claims do. ## Global Data Discrepancies Study three analyzed data from eight nations, including Brazil, Morocco, and Australia, using locally prominent narratives like the Beirut port explosion. The results showed that the mentality-centered hypothesis was falsified in six countries and remained inconclusive in others, further complicating the idea that a single mindset drives all conspiracy beliefs. ## The Rabbit Hole Effect Previous longitudinal research has suggested a mild rabbit hole effect, where believing in one conspiracy theory predicts small increases in believing others over time. This supports a network view where specific beliefs form a mutually reinforcing web, rather than being mere symptoms of a single, deep-seated personality trait or worldview. ## Statistical Model Comparisons To ensure robustness, the team performed resampling checks by randomly dropping questions to equalize the number of items between mentality and belief categories. These checks consistently echoed the main findings, showing that individual belief items often act as central hubs, contradicting the theory that a general mentality score explains everything. ## Limitations of Cross-Sectional Data All three studies analyzed survey responses gathered at a single point in time, which prevents researchers from establishing causality. While the maps show which beliefs are statistically linked, they cannot determine whether a broad mindset causes specific beliefs, or if adopting specific stories eventually builds a general conspiratorial worldview over time. ## Measurement Sensitivity Arturo Bertero emphasizes that results in conspiracy research depend heavily on how beliefs and mentality are measured. Because definitions of conspiracy mentality vary across the field, the assumed link between a general mindset and specific theories lacks direct evidence, necessitating more careful selection of tools based on the specific research question. ## Theoretical Interpretations Remain Open Two main interpretations remain: either a general mentality measure adds little value when specific questions already capture shared beliefs, or conspiracy beliefs form a self-sustaining web that cannot be reduced to an overarching mindset. The authors stress that their findings do not mean mentality measures should be abandoned in future studies. ## Future Research Directions The study highlights the need for longitudinal data to settle the direction of these relationships. Future research must move beyond snapshots to understand how these beliefs develop. Researchers should choose between general mentality scales and specific belief measures based on whether they are comparing across countries or investigating particular events. ## Sources covering this story - https://www.psypost.org/new-psychology-research-challenges-a-popular-explanation-for-why-conspiracy-theories-cluster-together/ — --- _Summary written by Brifing from the original reporting.
