Information Gerrymandering

INTRODUCTION
English translation pending.
CORE DEFINITION
Described by Alexander Stewart and colleagues in a paper in Nature, information gerrymandering is the manipulation of a network's connection structure so that a minority opinion determines group decisions even when no false information is present. Because individuals infer the majority view from their own neighbors, restructuring who sees whom biases those local impressions without changing any individual's information. The effect is the informational analogue of political gerrymandering. Key qualification: it requires control over network structure or recommendation algorithms, not merely over content.
SCAFFOLDING EFFECT
Reduce cognitive load
- Map the structure: check who can see whom before judging what a group actually believes. - Add bridges: create cross-group links so local impressions reflect the wider distribution. - Compare local and global: track whether your perceived majority matches population-level data.
Anchor fast decisions
Individuals estimate the majority position from the opinions visible in their own neighborhood. When the network is partitioned or its connections rewired, the visible sample becomes unrepresentative even though every individual holds accurate information. Aggregated across the group, these biased local estimates produce a collective outcome that the actual majority would not endorse.
