Human infants appreciate that information bears value for other individuals.
Article in Scientific reports, 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
Humans' ability to recognize each other as seekers of information is crucial for effectively sharing knowledge, evaluating confidence, and reasoning about the role of knowledge in behavior. Here, we investigate the foundations of this 'epistemic sense' through a series of looking-time experiments, asking whether 14-month-old human infants recognize and evaluate the information-directed goals behind others' actions. In Experiments 1-3, we assess infants' understanding of scenarios where an individual seeks information driven by uncertainty or curiosity about objects. In Experiment 4, we examine their expectations regarding the efficiency of such information seeking. Our results indicate that infants have a nuanced grasp of the principles guiding others' epistemic actions, including how uncertainty and novelty motivate information seeking, and that they also have expectations about the efficiency of such attempts in terms of maximizing information gain. This suggests that the foundational concepts for understanding the epistemic aspects of others' behavior develop early on.
