Their deliberative practice is crowdsourced policymaking where local and national governments engage citizens and gather ideas and knowledge to improve policies. They define crowdsourced deliberation as an asynchronous, distributed, and self-selected form of deliberation (reasoned argument exchange characterized by respect and reciprocity among the participants), and idea crowdsourcing (gathering idea contributions from online crowds). They focus on three features in deliberation: disagreement, agreement, and elaboration.

They use a crowdsourced law reform process led by Finland, coded them, and analyzed comments with inferential statistics.

They found that simultaneous presence of disagreement and agreement in comments was more strongly positively associated with idea generation than the presence of either disagreement or agreement alone or the absence of both. Moreover, the simultaneous presence of elaborated disagreement and elaborated agreement had the strongest positive association with idea generation. This suggests that elaboration accompanying dis/agreement—already considered an important marker of deliberative quality—can also contribute to idea generation in crowdsourced deliberation. They also find that disagreement can play a constructive role as long as it is civil and elaborated.

They implicate that elaboration should be prioritized for productive ideation and constructive argumentation.
