苏利文这个说法离“全面改口”差的远了。三年了,各种猜测多了,生物武器,自然源头,闫博士的舟山猴子,实验室泄露...现在能源部的这个不过是没有公布证据的低可信度猜测而已。
New assessment on the origins of Covid-19 adds to the confusion
and a low confidence assessment generally means that the information obtained is not reliable enough or is too fragmented to make a more definitive analytic judgment or that there is not enough information available to draw a more robust conclusion.

‘Not a definitive answer’
The latest intelligence assessment was provided to Congress as Republicans on Capitol Hill have been pushing for further investigation into the theory, while accusing the Biden administration of playing down its possibility.
House Foreign Affairs Chairman Michael McCaul said Sunday he was “pleased” the Energy Department “has finally reached the same conclusion that I had already come to.” (The Texas Republican had released a 2021 report that concluded that “the preponderance of the evidence” showed the pandemic originated with a leak from the Wuhan lab.)
“Now is the time for the entire Biden administration to join the Department of Energy, the Federal Bureau of Investigation, and the majority of Americans by publicly concluding what common sense told us at the start – the COVID-19 pandemic originated from a lab leak in Wuhan, China,” McCaul said in a statement.
Sullivan said Sunday that Biden had directed the national laboratories, which are part of the Department of Energy, to be brought into the assessment.
“Right now, there is not a definitive answer that has emerged from the intelligence community on this question,” Sullivan told CNN’s Dana Bash.
“Some elements of the intelligence community have reached conclusions on one side, some on the other. A number of them have said they just don’t have enough information to be sure.”
So where does that leave us? Not far from where we started.
Past pandemics have
emerged from natural transmission through animals, and it often takes months or years to discover the host that the virus passed through as it adapted to infect humans.
In some cases, as in Ebola, the original natural source has never been identified. And it’s been more than 40 years since the first cases of Ebola.
So why does it matter where Covid-19 came from? As Relman, the Stanford microbiologist, previously noted to CNN, finding the answer can help prevent the next pandemic.
Three years removed from the start of a Covid-19 pandemic that is still disrupting daily life, an assessment from the US Energy Department is only adding to the confusion about what really happened in Wuhan, China.
