IPPRA conducts research and builds partnerships by integrating public policy scholarship with the physical and engineering sciences. We aim to increase human well-being, improve social choice infrastructure, and enhance resilience by addressing complex public policy problems and creating opportunities that span natural, technological, and social systems. Our Research: Enables better public policy decision-making that serves the public interest, stakeholders, and decision makers. Provides data analysis on how individuals, groups, and decision-makers perceive and respond to an array of threats and opportunities. Focuses on the human element in complex systems with state-of-the-art theory, data collection and modeling of belief systems, social valuation, public choice, decision-making, human behavior, and public policy analysis methods. How We Do It: IPPRA employs a diverse range of modeling and state of the art social science methods to achieve a common systems perspective, seeking to integrate the social, natural, and technological components of a problem area. Our applications range from local to international in scope.
