Those inclined to think… that the pandemic must have started from a traded wild animal share a fundamental intuition with those who point their fingers at the lab: Theyโ€™ve both looked at all the facts and then identified a grand coincidence, and they both believe that their theoryโ€”and only their theoryโ€”can explain it.

A single question seems to be the fuel for every fight: What are the odds?ย
