Voting patterns overstate support in online community elections
Endorsement Without New Evidence: How Sequential Voting Inflates Mandates in Online Community Governance
Social and Information NetworksComputers and SocietyHuman-Computer Interaction
Summary
Sometimes in online communities, a big win in a public vote is seen as strong support, but this study shows that later voters often repeat earlier opinions without adding new reasons. The researchers looked at Wikipedia admin elections and found that votes arriving later tend to have weaker explanations, suggesting people rely on previous comments more than their own judgment. This can create a false sense of overwhelming agreement even though the actual scrutiny might be limited. However, these large margins do not seem to harm the quality or activity of the elected admins.
What this means in practice
- •For online community managers: Detect weaker independent support in community elections to improve election process transparency and interpretation of mandate strength.
- •For platform designers: Design voting systems that reduce signal distortion caused by sequential endorsements and enhance meaningful voter input.

Abstract
Online communities often treat large support margins in public elections as strong mandates. We argue that such margins can overstate the independent scrutiny behind a decision. Using 198,275 free-text rationales from Wikipedia admin elections, we introduce vote-text divergence, a measure that flags a decisive vote paired with a thin, deferential rationale. Divergence rises as voters arrive later, even after controlling for voter and election fixed effects. The pattern is consistent with information saturation: once prior text is accounted for, arrival order no longer predicts divergence, while accumulated prior evidence does. The effect is strongest among peripheral voters in the co-voting network. Yet divergence does not predict worse post-promotion outcomes, such as administrative activity or survival. Public tallies can therefore weaken the scrutiny signal even while selecting capable administrators: a margin may appear to reflect more consensus and support than it actually contains.
