Differential pathways from personality to risk-taking: how extraversion and negative emotionality shape decision-making through overconfidence.

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
Introduction: Understanding mechanisms through which personality traits influence risk decision-making remains crucial in behavioral research. This study examined overconfidence as a mediator in personality-risk relationships, focusing on Extraversion and Negative Emotionality. Methods: We recruited 110 university students to complete the Game of Dice Task, Big Five Inventory-2, and General Knowledge Questionnaire. Mediation analyses using bootstrapping methods examined direct and indirect effects with demographic controls. Results: Mediation analyses revealed distinct patterns. Extraversion demonstrated partial mediation through overconfidence (indirect effect: β = 0.101, 95% CI [0.012, 0.228]), explaining 20.5% of the total effect. Negative Emotionality showed complete mediation through overconfidence (indirect effect: β = -0.216, 95% CI [-0.364, -0.091]), accounting for 72.8% of the total effect. The models explained 29.4% and 22.9% of variance respectively. Discussion: These findings demonstrate that personality traits influence risk decisions through distinct pathways: Extraversion operates through both direct behavioral tendencies and cognitive biases, while Negative Emotionality primarily influences risk behavior through confidence calibration. Results provide implications for theoretical development and practical interventions, suggesting personality-tailored approaches to risk management.
