摘要	The policy Delphi is a structured, iterative technique for eliciting and organising informed opinion on contested policy issues. Unlike the classical Delphi, which seeks consensus on a forecast, the policy Delphi is explicitly designed to generate the strongest possible opposing positions on a policy question and to expose the full range of options, supporting arguments and disagreements among a panel of knowledgeable stakeholders. Introduced by Murray Turoff in 1970, it conducts several anonymous rounds in which participants rate policy statements on dimensions such as desirability and feasibility, see aggregated feedback and the reasoning behind divergent views, and revise their positions — surfacing structured intelligence for decision-makers rather than a forced agreement.	The Delphi method is a structured, iterative survey technique developed by Norman Dalkey and Olaf Helmer at the RAND Corporation in 1963 for eliciting and converging expert opinion on complex topics where empirical data are unavailable or insufficient. It collects independent judgements from a geographically dispersed expert panel over multiple anonymous rounds, feeding aggregated results back to participants after each round so they can revise their views in light of the group's collective position.
