More Experts


Andrew M. Parker is co-director of the Center for Decision Making under Uncertainty and a senior behavioral and social scientist at the RAND Corporation. His research applies core concepts in behavioral decision research to the understanding of decisionmakers' behavior in complex, real-world situations. He has led or contributed to RAND projects on decision quality, risk perception, and group decisionmaking, involving such content domains as health and financial behavior, aging, public health emergency preparedness, long-range planning for climate change, and psychological health. Past projects have addressed decisionmaking in low-income consumption, adolescent sexual and contraceptive behavior, retirement planning, drug and alcohol use, expectations for major life events, and public responses to risk information. Parker was principal investigator on a National Science Foundation-funded project validating an adult measure of decisionmaking competence, which has been used to predict major life outcomes. He currently co-leads a National Institute of Allergies and Infectious Diseases-funded project examining how influenza risk perceptions propogate across social networks and influence vaccination decisions. He received a B.A. in psychology and statistics from the University of Michigan, Ann Arbor; an M.S. in statistics and an M.S. behavioral decision theory, both from Carnegie Mellon University; and a Ph.D. in behavioral decision theory, also from Carnegie Mellon.

    How the Public Perceives Ebola Risk in the United States

    The Ebola outbreak in Africa and the cases in the United States weighed heavily on the minds of policymakers and the public. While the Ebola threat was (and is) certainly real, many Americans greatly overestimated their chances of contracting the deadly disease.

    An Outbreak of Outbreaks

    Lately, stories about outbreaks seem to be spreading faster than the diseases themselves. An outbreak of measles in Ohio is just part of an 18-year high of U.S. cases. Meanwhile, polio continues to circulate in Pakistan, Afghanistan, and Nigeria, while spreading to other countries, like Cameroon, Equatorial Guinea, and Syria.
