Brigitte Lebens Nacos (born 1936) is an adjunct professor in political science at Columbia University. She has written on the news media, the politics of Germany, and terrorism.
Nacos is a joint author of a paper, "Prevention of Terrorism in Post-9/11 America", which was delivered at the Summer 2006 meeting of the American Political Science Association. The paper studied the correlation between increases in terrorism alert levels and the popularity of then-U.S. President George W. Bush. Referring to the predictions in her study, journalist Matthew Stannard wrote in the San Francisco Chronicle, "The media will repeat the president's remarks. Public fear of terrorism will increase. And the president's poll numbers will rise."
Nacos holds a B.A., M.Phil., and Ph.D., all from Columbia University.
