Income Inequality and Self-Serving Belief in Burden-Sharing: An Experimental Study.
Article in Behavioral sciences (Basel, Switzerland), 2025. 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
Public goods games under asymmetric endowments have been widely discussed in the literature; however, few studies have addressed how inequality influences normative beliefs and the subsequent burden-sharing behaviors. To address this gap, we conducted two online survey experiments in both hypothetical and real-income scenarios, focusing on the mediation effects of self-serving bias and other-regarding preferences. The findings showed that while unequal endowment status induced self-serving personal beliefs and burden-sharing behaviors, it also enhanced reciprocity and offset self-serving bias in a real-income scenario. Only high-endowment status significantly influenced beliefs and behaviors. This study reveals a trade-off between self-serving bias and reciprocity in social cooperation, offering new insights for fairness beliefs.
