The Wuhan Institute of Virology, Chinese Academy of Sciences (WIV; Chinese: 中国科学院 武汉病毒研究所), located in Jiangxia District, Wuhan, Hubei, is a research institute on virology.

Seventeen months into the news cycle surrounding those questions (they were first publicly hinted at in a tweet on Jan. 5, 2020), they're still putting off lots of heat and very little light. And that's likely to remain the case, because the "Wuhan Lab Leak theory" is not a theory.

A theory has to be objectively testable such that if it's false it can be PROVEN false. Otherwise, it's just a hypothesis.

If my car keys go missing, I can hypothesize that little green faeries (who have the power to fool security cameras) took them in the middle of the night, then forgot to put them back after taking my car out for a joyride, filling the gas tank back up, parking it back where they found it, and rolling back the odometer.

My hypothesis "explains" the missing car keys. But it can't be falsified. If I find the keys in my jacket pocket, well, the faeries obviously put them there, dummy!

Many "conspiracy theories" are just hypotheses which continuously change to accommodate any evidence that might disprove them.

No, I'm not saying the "Wuhan Lab Leak" hypothesis is a wild-eyed "conspiracy theory." But it's also not likely testable or falsifiable.

For one thing, the Chinese regime, while notable for many things, is not notable for its likely willingness to let western investigators poke around Wuhan at will, actively assisting those investigators in determining whether it accidentally or intentionally killed millions of human beings and cratered the global economy.

For another, the regimes urging such an investigation have a long record of lying about pretty much everything (does "Saddam has WMD" ring any bells? How about "the NSA doesn't spy on Americans?"), and have already spent a good deal of time setting China up as their latest "adversary." It's hard to imagine any situation in which those who WANT to believe in — or stand to gain political power from selling — the "Wuhan Lab Leak" hypothesis would concede that they were mistaken.

It's a hypothesis, not a theory, and it's likely to stay that way. When dealing with hypotheses, our best analytical tool is Occam's Razor. Simple version: The explanation requiring the fewest assumptions is the likeliest.

Which explanation requires fewer assumptions?

That, like most human infectious diseases (60% according to the US Centers for Disease Control), SARS-COV-2 jumped from animals to humans via random mutation?

Or that, unlike (almost — the 2001 anthrax attacks may be an exception) any other past disease, SARS-COV-2 was weaponized in a lab and released into the human population?
