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

Awareness of past atrocities is widely seen as critical for restoring justice and building resilient democracies. Going beyond information provision, an increasing number of memorial sites, museums, and historical archives offer opportunities for public participation. Yet little empirical evidence exists on the impact of participation in the collective remembrance of past atrocities. Two experimental studies, a field-in-the-lab study with 552 university students in Germany and an online randomized control trial with 900 digital workers in Germany, showed that participating in a large-scale, digital-history project about Nazi persecution increased peoples' collective-action intentions for further commemoration activities and for activities that strengthen intergroup relations today. These effects persisted for 2 weeks. The findings suggest that digital-history projects can motivate collective action that is critical for symbolic justice and positive intergroup relations, thus contributing to well-functioning, pluralistic democracies.
