根据最近提供给白宫和国会主要成员的一份机密情报报告，美国能源部得出结论，新冠大流行很可能是由实验室泄漏造成的。
。。。
阅读过这份机密报告的人士表示，能源部对此的判断“信心不足”，或者叫“低置信度”。
读了WSJ 的原文，原来才知道，能源部不是对证据是低度信心，而是对结论是低度信心。同时，在这里“Low confidence" 和 ”信心不足“是不一样的。中文里信心不足，可能是说这个结论可能是错的。但conclude somthing with low confidence 还是说这个结论可能是真的，但信心不足以到可以相信或者确信的地步。

WASHINGTON—The U.S. Energy Department has concluded that the Covid pandemic most likely arose from a laboratory leak, according to a classified intelligence report recently provided to the White House and key members of Congress.
The shift by the Energy Department, which previously was undecided on how the virus emerged, is noted in an update to a 2021 document by Director of National Intelligence Avril Haines’s office.
The new report highlights how different parts of the intelligence community have arrived at disparate judgments about the pandemic’s origin. The Energy Department now joins the Federal Bureau of Investigation in saying the virus likely spread via a mishap at a Chinese laboratory. Four other agencies, along with a national intelligence panel, still judge that it was likely the result of a natural transmission, and two are undecided.
The Energy Department’s conclusion is the result of new intelligence and is significant because the agency has considerable scientific expertise and oversees a network of U.S. national laboratories, some of which conduct advanced biological research.
The Energy Department made its judgment with “low confidence,” according to people who have read the classified report.
