Cornell professor Joseph Margulies discusses the issue of bias in the U.S. Intelligence Community (IC) and the need for research into public trust in the IC, particularly in the current “post-truth” era. Professor Margulies argues that while existing research suggests broad public support for the IC, more comprehensive and nuanced research is needed to understand how the current partisan and “post-truth” environment may be eroding trust in the intelligence function, and that the Department of Defense should commission such research to inform its understanding of and response to this issue.
