Critical thinking wasn’t helped when some prominent scientists (David Baltimore, Richard Ebright) weighed in with arguments based more on authority than evidence in favor of the lab leak hypothesis. The mountain of data that has accumulated since then points heavily in favor of natural origins. Baltimore has stated publicly that he regrets his earlier assertions.
Kevin Drum, who is not a molecular biologist or a virologist nevertheless has a nifty summary of the current state of scientific evidence, which still points to natural origins. Does this prove that COVID-19 wasn’t engineered or the result of a lab leak? No. It is impossible to prove a negative, and anyway, science doesn’t deal in proofs, it deals in the weight of evidence.
