Voting Biases in Decentralized Autonomous Organization (DAO) Governance

AI Summary

This study addresses the persistent puzzle of highly concentrated support in DAO voting by empirically analyzing governance mechanisms at the proposal-option level. It reveals, for the first time, that interface design features—such as author pre-selection, approval-oriented framing, and top-list placement—systematically skew vote weight distribution, demonstrating that interface design constitutes a critical institutional choice. Employing robustness checks through controlled author self-voting weights and multiple model specifications, the analysis shows that author pre-selection increases an option’s received vote weight by 58.8%, approval-oriented design by 27.1%, and top-list placement by 7.7%. These findings underscore the profound impact of governance interface design on the fairness of decentralized decision-making.

Abstract

Decentralized Autonomous Organizations (DAOs) use token-weighted voting to allocate resources, set protocol rules, and legitimate collective decisions. Yet, support in DAO voting is strikingly concentrated. What happens inside the ballot that produces this concentration? We study DAOs' governance at the proposal-choice level, linking each choice's voting-power share to three observable features: whether it expresses an approval-oriented stance, where it appears in the choice list, and whether it is selected by the proposal author. We find that (i) author-selected choices show the strongest and most robust association with voting-power share, with a 58.8% increase relative to non-author choices; (ii) approval-oriented choices retain a positive but slightly less consistent advantage (27.1%); and (iii) first-listed choices also attract systematically higher shares, consistent with position and order effects (7.7%). Results are robust across several specifications, which include subtracting an author's own voting power from computations. We use bias descriptively, to denote systematic associations rather than proven causal distortion. The results shift attention from proposal outcomes alone to the interface and social signals through which choices are presented. In DAO governance, ordering, author signals, and vote visibility should be treated as institutional design choices, not neutral implementation details.
