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

Increasing geographical and cultural diversity in research participation has been a key priority for psychological researchers. In this article, we track changes in participant diversity in developmental science over the past decade. These analyses reveal surprisingly modest shifts in global diversity of research participants over time, calling into question the generalizability of our empirical foundation. We provide examples from the study of early child development of the significant epistemic and ethical costs of a lack of geographical and cultural diversity to demonstrate why greater diversification is essential to a generalizable science of human development. We also discuss strategies for diversification that could be implemented throughout the research ecosystem in the service of a culturally anchored, generalizable, and replicable science.
