With the arrival of Ebola on U.S. soil came the wall-to-wall media coverage one might expect. 

But does saturated coverage of threats like the Ebola virus and Islamic State militants do more harm than good and inspire less-than-rational thinking? 

In this week's "Two Guys on Your Head," Dr. Art Markman and Dr. Bob Duke join KUT's Rebecca McInroy to talk about how the 24-hour news cycle causes readers, listeners and viewers to vicariously experience seemingly far-away threats, and how the availability of instant news causes some people to irrationally assess risks and threats.
