In many public policy situations, formal negotiations and collective problem solving are inhibited by a lack of good ideas that can get the buy-in and support of all involved stakeholders. We suggest that devising seminars provide a promising approach for helping to overcome this barrier. A devising seminar is an off-the-record, facilitated workshop that brings together representatives of core stakeholding interest groups to brainstorm mutually advantageous approaches to address collective challenges. In this article, we explain what devising seminars are, how they work, and how they can help with complex public policy disputes. We illustrate through the case of the Devising Seminar on Arctic Fisheries and conclude with lessons learned from that experience.
