Abstract: | The quality of deliberative conversations are dependent on citizens compliance with deliberative norms yet there is a lack of methods to assess norm compliance in discussions. Here, the psychological construct of complexity of thinking is claimed to conceptually correspond to the deliberative conversational ideal and adopted as a measurement of deliberative norm compliance. The hypothesis that citizens' complexity of thinking increases as a result of participation in deliberative conversations was tested in a minipublic case study in Sweden. Participants' complexity of thinking was assessed before and after deliberation by responding to an open‐ended question about the topic of debate. Manual coding was used to rate participants integrative complexity. The result confirms the hypothesis, which serves as an indicator of deliberative quality. The study also demonstrates that women get higher increases in complexity, as do highly agreeable individuals and those who hold more liberal views. The findings demonstrate the potential usefulness of integrative complexity as a measurement of deliberative quality. |
