The Dark Tetrad and academic dishonesty: a systematic review and narrative synthesis of personality predictors of cheating, plagiarism, and deception in education.
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
backgroundThe subclinical personality traits of Machiavellianism, narcissism, psychopathy, and everyday sadism (i.e., the Dark Triad/Tetrad) have been linked to a range of antisocial and deceptive behaviours. With increasing concern about integrity in higher education, it is important to understand how these traits relate to academic misconduct with AI-assisted misconduct becoming more commonplace.
methodsThis systematic review and narrative synthesis examined evidence from 23 studies that investigated associations between dark traits and dishonest academic practices, including plagiarism, exam cheating, contract cheating, academic dishonesty, and AI-assisted cheating.
resultsPsychopathy showed the most consistent pattern of associations across misconduct behaviours. Machiavellianism was associated with some forms of dishonesty, such as plagiarism and cheating, but was not consistently associated with contract cheating. Narcissism showed weaker and more context-dependent associations. Everyday sadism was examined in comparatively few studies. Preliminary evidence linked sadism to some forms of academic dishonesty, including lying in academic contexts and AI assisted misconduct, but the small evidence base means that conclusions about its contribution to the Dark Tetrad framework remain tentative.
conclusionsFurther research is needed before stronger conclusions can be drawn about sadism's role in academic misconduct. Future directions and implications, including suggestions for replication and expansion, are discussed.
