Deliberative Opinion Polls (DOPs) measure informed opinion on an issue. They differ from ordinary opinion polls in that participants are informed via briefing notes and access to experts (these may include politicians) and have time to consider the issue in detail, whereas participants in ordinary opinion polls do not have the opportunity to learn about the issue (and so may know little about it), and have no opportunity to deliberate on it, alone or with others.
