Building on recent insights from psychology, linguistics and philosophy about the role of questions in speech and thought, we propose a different model in which beliefs are treated as answers directed at specific questions. Here, questions are formally represented as partitions of the space of possibilities and individuals\u2019 information states as sets of questions and corresponding partial answers to them. The state of conversation is then characterised by individuals\u2019 information together with the questions under discussion, which can be steered by various deliberative inputs.\u00a0Using this model, deliberation is then shown to shape collective decisions in ways that classical models cannot capture, allowing for novel explanations of how group consensus is achieved.<\/jats:p>","DOI":"10.1007\/s00355-022-01392-9","type":"journal-article","created":{"date-parts":[[2022,3,29]],"date-time":"2022-03-29T16:24:02Z","timestamp":1648571042000},"page":"581-600","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Million dollar questions: why deliberation is more than information pooling"],"prefix":"10.1007","volume":"63","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5331-2409","authenticated-orcid":false,"given":"Daniel","family":"Hoek","sequence":"first","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2184-7844","authenticated-orcid":false,"given":"Richard","family":"Bradley","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2022,3,29]]},"reference":[{"issue":"2","key":"1392_CR1","doi-asserted-by":"publisher","first-page":"209","DOI":"10.1017\/S0003055406062113","volume":"100","author":"D Austen-Smith","year":"2006","unstructured":"Austen-Smith D, Feddersen TJ (2006) Deliberation, preference uncertainty, and voting rules.
