The Wuhan lab theory is a media warning

We engaged in availability bias: Instead of letting the evidence or lack thereof guide us, we adopted the attitudes of public figures whose political, cultural and social status we wished to emulate. Most insidiously, we relied on a fallacy sometimes known as “alleged certainty”: “The question remains open” is not a headline that attracts clicks. A headline that does is “lab leak theory again proves Trump’s incompetence.” Alas, the question of Covid’s origins not only remains open; in all likelihood it will defy final resolution unless and until the Chinese government is forthcoming with its own records, which it has shown a predilection not to be. The lab leak hypothesis has an unsettling corollary. In nature, the giant mixing bowl of natural selection is mechanism enough to explain how a virus adapted to bats might mutate to become infectious in humans. If it escaped from a lab, how did such a virus acquire the ability to infect humans? “Gain of function” experimentation was a controversial practice among virologists long before Covid. Multiple accidental releases of dangerous viruses from highly secure labs have been recorded in the past. The SARS virus has escaped six times since being identified in 2003. The 1977 global flu pandemic is believed to have originated in the escape from an unknown lab of a specimen collected in the 1950s.
