Sharing perspectives to understand the interests, values, and feelings of others is needed in deliberation to reach a compromise, particularly in the case of issues surrounding risks and negative goods burden-sharing. Using role-play games can allow participants to feel a real connection with the people most concerned, encouraging empathic consideration. This study aims to understand how perspective-taking through role-play games can encourage empathy in underlying common good values. Following the 2011 Fukushima nuclear accident, decontamination efforts led to the storage of removed soil around the plant. To reduce the burden of the affected area, final disposal of the soil outside of Fukushima prefecture by 2045 was mandated by law. To share possible narratives surrounding the issue, an experiment using role-play games was created, allowing participants to experience multiple roles and perspectives. It was separated into three stages: a negotiation among prefecture delegates responsible for policy decisions, a debate between residents and administrative staff in a local community, and a deliberation by a citizen panel unrestricted by interests and positions. The first stage created a condition where consensus was difficult to reach due to divergent interests, while the second stage showed the possible implications and local protests from residents. Lastly, having experienced different perspectives and how they created a conflictual situation, participants were asked to propose policies to improve the social acceptability of the removed soil in the third stage. The results of conducting the game indicated that the more a consensus couldn't be reached in stages 1 and 2, the more proposals reducing the burden were suggested in stage 3. The game facilitated perspective-taking and empathy, encouraging participants to propose more inclusive policies. This study shows an application of role-play games as a mediator for perspective-taking, fostering social acceptability of burden-sharing projects.
