Özet	Deliberative Polling is a method, devised by James Fishkin, that combines the representativeness of a scientific opinion survey with the informed reflection of deliberation. A large, random and representative sample of citizens is first polled on an issue, then gathered to deliberate over balanced materials and dialogue with experts and one another, and finally polled again. The change between the before and after surveys reveals what the public would think about an issue if it were genuinely informed and had the opportunity to consider it — Fishkin's idea of 'counterfactual' or considered public opinion.	The Nominal Group Technique (NGT) is a structured group facilitation method designed to generate and prioritise ideas, problems, or solutions while ensuring equal participation from all members. Developed by Delbecq and Van de Ven in 1971, it combines silent individual idea generation with structured group discussion and systematic voting to produce a ranked list of priorities. Unlike unstructured focus groups, NGT prevents dominant voices from suppressing quieter participants, making it especially valuable for needs assessment, program planning, and stakeholder priority-setting in applied research and policy contexts.
