Research Summary: Endorsement Without New Evidence: How Sequential Voting Inflates Mandates in Online Community Governance

Research into online community governance processes, specifically sequential voting in public elections, indicates that large support margins may not always reflect independent scrutiny. The study, using data from Wikipedia admin elections, identifies 'vote-text divergence' as a metric to measure thin, deferential rationales accompanying decisive votes. This divergence increases with later voter arrival, suggesting an 'information saturation' effect where accumulated prior evidence influences votes more than independent assessment, particularly among peripheral voters.

Why it matters

This research highlights a potential bias in online decision-making processes, where the perception of a strong mandate might be inflated due to sequential voting dynamics rather than independent assessment. Understanding this mechanism is crucial for designing more robust and genuinely representative governance structures in digital environments, ensuring that perceived consensus reflects true scrutiny.

Key insights

• Large support margins in online community elections can overstate the independent scrutiny behind a decision.
• The study introduces 'vote-text divergence' to quantify decisive votes paired with thin, deferential rationales.
• Vote-text divergence increases as voters arrive later in a sequential voting process, even when controlling for individual voter and election specific factors.
• This pattern is consistent with 'information saturation,' where the order of arrival predicts divergence, and accumulated prior evidence influences voting.
• The effect of information saturation and increased divergence is most pronounced among peripheral voters within the co-voting network.
