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

backgroundResearch on negativity bias demonstrates that negative information receives disproportionate cognitive attention at the individual level, but how this psychological mechanism shapes collective emotional patterns remains unclear. We investigate whether communities systematically concentrate negative emotions on fewer targets while distributing positive emotions more broadly.

methodsWe analyze 36,223 German football fans' reports of loved and hated clubs, measuring attention concentration using the Herfindahl-Hirschman Index (HHI). We distinguish between outgoing concentration (how communities allocate their own attention) and incoming concentration (how attention from others focuses on particular targets), testing whether concentration differs between positive and negative affect.

resultsNegative attention was significantly more concentrated than positive attention for both outgoing (M = 0.36 vs M = 0.23, p < 0.001) and incoming ties (M = 0.41 vs M = 0.33, p = 0.011). Love and hate concentration are weakly correlated (r = 0.26-0.32), indicating independent processes. Structural factors predict incoming but not outgoing concentration (Pseudo R2 = 0.14-0.35 vs R2 = 0.47-0.49), revealing asymmetric mechanisms of attention allocation versus attraction.

conclusionsCommunities face cognitive constraints that produce systematic asymmetries in how they distribute emotional attention. These findings highlight how cognitive constraints shape collective emotional structures, with implications for political polarization, consumer behavior, and conflict dynamics.
