> For instance, a neuroscientist belonging to a group that claims to independently investigate COVID-19 tweeted that the letter is a diluted version of ideas his group posted online last year. The same week, on Twitter, the neuroscientist also lashed out at Rasmussen, who has tried to explain studies suggesting a natural origin of SARS-CoV-2 to the public. He called her fat, and then posted a derogatory comment about her sexual anatomy. Rasmussen says, “This debate has moved so far from the evidence that I don’t know if we can dial it back.”
Pursuing the lab-leak theory more aggressively will not improve the state of scientific knowledge. It might improve the state of scientific practice (e.g. lab safety protocol or advisability of gain-of-function research), but given how much the spotlight has already been on these issues regardless of virus origin I'm skeptical of that too. The only thing driving this is politics, either classic geopolitics or the politics that exist between pathological contrarians and any kind of established experts. It's the latter we're seeing here, day after day after day, and TBH it's a very ugly thing.
Perhaps this can serve as a wake up call for the scientific community to develop its "metascience" practices.
