Emotional pathways linking relative deprivation experiences to conspiracy beliefs: a mini-meta-analysis.
Synthesis in BMC psychology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundConspiracy beliefs pose a societal challenge, yet the processes through which they emerge remain debated. One pathway to conspiracy beliefs that has received limited attention is the role of emotional responses to relative deprivation (RD). RD - the perception of being unfairly disadvantaged- elicits negative emotions such as anger and disgust, which may in turn foster conspiratorial interpretations.
methodsAcross eight preregistered studies (N = 3,306), we experimentally induced direct, individual-level RD using a validated unfair-outcome paradigm and assessed anger, disgust, and (exploratorily) anxiety. All studies measured conspiracy mentality and specific conspiracy beliefs.
resultsWe synthesized study-wise effects in a random-effects mini-meta-analysis. Experimentally induced RD reliably increased negative emotional responses (i.e., anger and disgust across all studies). Anger and disgust, but not anxiety were associated with both conspiracy mentality and specific conspiracy beliefs. Mini-meta-analytic mediation analyses showed consistent indirect effects of RD on both conspiracy outcomes through negative emotions. Total effects of RD on conspiracy beliefs, however, were very small and varied in direction across studies, underscoring the importance of emotional mechanisms.
conclusionsThe findings indicate that direct experiences of RD may promote conspiracy beliefs indirectly through heightened anger and disgust. This work highlights results that are consistent with an important role of momentary emotional responses in the emergence of conspiracy beliefs and advances understanding of the affective mechanisms linking RD to conspiratorial thinking.
