Joe Arvai is an associate research scientist at Decision Research, and he is the Max McGraw Professor of Sustainable Enterprise in the School of Natural Resources & Environment, and the Ross School of Business at the University of Michigan. Joe’s research has two main areas of emphasis: First, his research is focused on advancing our understanding of how people process information and make decisions, with a specific emphasis on the interplay between cognitive and affective modes of judgment. Second, Joe and his team conduct research focused on developing and testing decision aiding tools that can be used by people to improve decision quality across a wide range of environmental, social, and economic contexts. These decision support systems can be classified as active (in that they decompose complex problems into more cognitively manageable parts) or passive (in that they modify human behavior in self-interested directions without modifying people’s decision-making tendencies). In addition to his research, Joe is a member of the U.S. Environmental Protection Agency’s Science Advisory Board, and is a member of the U.S. National Academy of Sciences’ Board on Environmental Change and Society.
