In the final episode in our series on Junk News, some wisdom from one of the leading experts in the murky world of online misinformation. He also happens to be the producer of the series that we aired on the PBS NewsHour. Now he's taking the software he wrote to Harvard, where they hope to find new ways to combat Junk News. I hope you enjoy this talk with Cameron Hickey, my friend and soon-to-be former colleague.
