Megyn, to give her credit, asks him why he hasn't put anyone representing the orthodox viewpoint on his podcast, to counterbalance Kory or Malone & Kirsch. In doing so, she articulates the vulgar heuristic available to the public:
Megyn: When I started researching... where did they all get this information, I found that it's from this one guy's study, Byram Bridle, he is an associate professor of viral immunology in the department of pathobiology at the university of Guelph in Canada. Guelph, that is.
