The 15th International Conference of Naturalistic Decision Making will take place in conjunction with the Resilience Engineering Symposium from June 21st-24th, 2021. We are excited to join forces and look forward to new insights and lively discussion as these two communities come together. We are planning for a traditional conference meeting in Toulouse, France; however, this is subject to potential COVID restrictions. We may hold a hybrid meeting, with some people gathering in Toulouse and others joining virtually, or host smaller regional meetings in place of one large meeting. Details about the conference will be posted on this page as they become available. You can also find information about this joint meeting by visiting the Resilience Engineering Association’s symposium page.
