Matt Kibbe is joined by Matt Ridley, author of “Viral: The Search for the Origin of COVID-19,” to discuss the constantly shifting media narrative surrounding the coronavirus pandemic, including the once taboo “lab-leak hypothesis.” Ridley runs down the evidence for the hypothesis, including why the original story about Chinese wet markets makes no sense, and addresses the controversy about gain-of-function research. He also lays out the costs — in terms of reputation, harassment, and bullying — that he and his co-author have paid for being willing to contradict the scientific and medical establishment on this issue.
