We study a setting in which a community wishes to identify a strongly supported proposal from a large space of alternatives, in order to change the status quo. We describe a deliberation process in which agents dynamically form coalitions around proposals that they prefer over the status quo. We formulate conditions on the space of proposals and on the ways in which coalitions are formed that guarantee deliberation to succeed, that is, to terminate by identifying a proposal with the largest…

Democratic Forking: Choosing Sides with Social Choice

TLDR
This work provides a social choice setting in which agents can report preferences not only over a set of alternatives, but also over the possible forks that may occur in the face of disagreement, concentrating on stability issues and concerns of strategic agent behavior.

Complexity of Deliberative Coalition Formation

TLDR
It is proving that in both models it is hard to find a proposal with a high degree of support, and even a 2-compromise transition may be hard to compute, and strengthening the lower bound on the size of the compromise for the d-hypercube model from d to 2^Ω(d).

Foundations for Grassroots Democratic Metaverse

While the physical lives of many of us are in democ-racies (one person, one vote — e.g., the EU and the US), our digital lives are mostly in autocracies (one person, all votes — e.g., Facebook).

Iterative Deliberation via Metric Aggregation

TLDR
A general model consisting of a community of n agents, each with their initial ideal point in some metric space, such that in each iteration of the iterative deliberation process, all agents move slightly closer to the current winner, according to some voting rule R.

Sequential Deliberation for Social Choice

TLDR
The general method is described and it is shown that for general metric spaces, the second moment of of the distribution of social cost of the outcomes produced by sequential deliberation is also bounded.

Dynamic Coalition Formation and the Core

Deliberation and Voting Rules

We analyze a formal model of decision-making by a deliberative committee. There is a given binary agenda. Individuals evaluate the two alternatives on both private and common interest grounds. Each

Towards Large-Scale Deliberative Decision-Making: Small Groups and the Importance of Triads

TLDR
This model considers a group of participants, each having an opinion which together form a graph, and shows that for median graphs, it is possible to use a small number of three-person interactions to tightly approximate the wisdom of the crowd, defined here to be the generalized median of participant opinions, even when agents are strategic.

Deliberation, Single-Peakedness, and the Possibility of Meaningful Democracy: Evidence from Deliberative Polls

Majority cycling and related social choice paradoxes are often thought to threaten the meaningfulness of democracy. Deliberation can protect against majority cycles—not by inducing unanimity, which

Sequential decision making in repeated coalition formation under uncertainty

TLDR
Novel, non-myopic learning algorithms are presented to approximate the optimal Bayesian solution to coalition formation, providing tractable means to ensure good sequential performance and enabling the Bayesian agents to transfer acquired knowledge among different dynamic tasks.

Reaching a Consensus

Abstract Consider a group of individuals who must act together as a team or committee, and suppose that each individual in the group has his own subjective probability distribution for the unknown

A Voting Argumentation Framework: Considering the Reasoning behind Preferences

TLDR
This paper proposes a decision-making procedure based on argumenta-tion and preference aggregation which permits the effect of reasoning and deliberation along with voting for the decision process and quantifies the deliberation phase by defining a new voting argumentation framework and proving its acceptability semantics based on the notion of pairwise comparisons between alternatives.

A study in the pragmatics of persuasion: a game theoretical approach

TLDR
It is proved that there always exists a persuasion rule involving no randomization and that all optimal persuasion rules are ex-post optimal.

Deliberation, Single-Peakedness, and Coherent Aggregation

Rational deliberation helps to avoid cyclic or intransitive group preferences by fostering meta-agreements, which in turn ensures single-peaked profiles. This is the received view, but this paper
