Our Story

For nearly four decades, the field of Naturalistic Decision Making (NDM) has been concerned with the study of how people make decisions in complex real-world settings that can include dynamic, uncertain and continually changing conditions, and can require real-time decisions in urgent situations with significant consequences for mistakes. What we have learned about NDM has changed the way we train decision makers, the types of decision support we provide, and the way we design organizations. 

The NDM conferences have been the world’s leading conferences on Naturalistic Decision Making since 1989. The conferences have alternated between the U.S. and Europe biennially, and have served to disseminate new development in knowledge elicitation, training, system design, evaluation, and teamwork.

The NDM Association was incorporated in 2021.
