1 · What the graph read from it

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.

2 · The registry

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

Previous research has not yet identified the psychological mechanisms underlying the impact of resource inequality on cooperative behavior. To further explore this issue, this study used two single-factor experiments to investigate the influence of resource inequality on cooperative behavior in social dilemmas, focusing on the mediating role of fairness perception and group identity. The results showed that behavioral heterogeneity was higher under unequal conditions than that under equal conditions. In addition, in unequal groups, high-endowment players exhibited lower cooperation levels than low-endowment players. However, the mediating roles of fairness perception and group identity were not confirmed. This study highlights the complexity of resource inequality's influence on group cooperation and offers new directions for future research.
