For this episode of BioScience Talks, we're joined by Michael Patrick Lynch, who is the author of the new book On Truth and Politics: Why Democracy Demands It, available for presale from Princeton University Press. He is also the Board of Trustees Distinguished Professor of Philosophy and the Provost Professor of Humanities at the University of Connecticut, and he is the author of other books like Know-It-All Society and The Internet of Us.  Our discussion was focused on how scientists can effectively convey truth to a variety of audiences in our current political and technological context, as well as a number of other topics that will be of interest to all scientist–communicators.
