While I wasn't at 80% of a lab leak when Eliezer asseted it a month ago, I'm now at 90%. It will take a while till it filters through society but I feel like we can already look at what we ourselves got wrong.
In 2014, in the LessWrong survey more people considered bioengineered pandemics a global catastrophic risk then AI. At the time there was a public debate about gain of function research. On editoral described the risks of gain of function research as:
Insurers and risk analysts define risk as the product of probability times consequence. Data on the probability of a laboratory-associated infection in U.S. BSL3 labs using select agents show that 4 infections have been observed over <2,044 laboratory-years of observation, indicating at least a 0.2% chance of a laboratory-acquired infection (5) per BSL3 laboratory-year. An alternative data source is from the intramural BSL3 labs at the National Institutes of Allergy and Infectious Diseases (NIAID), which report in a slightly different way: 3 accidental infections in 634,500 person-hours of work between 1982 and 2003, or about 1 accidental infection for every 100 full-time person-years (2,000 h) of work (6).
A simulation model of an accidental infection of a laboratory worker with a transmissible influenza virus strain estimated about a 10 to 20% risk that such an infection would escape control and spread widely (7). Alternative estimates from simple models range from about 5% to 60%. Multiplying the probability of an accidental laboratory-acquired infection per lab-year (0.2%) or full-time worker-year (1%) by the probability that the infection leads to global spread (5% to 60%) provides an estimate that work with a novel, transmissible form of influenza virus carries a risk of between 0.01% and 0.1% per laboratory-year of creating a pandemic, using the select agent data, or between 0.05% and 0.6% per full-time worker-year using the NIAID data.
Even at the lower bar of 0.05% per full-time worker-year it seems crazy that society continued playing Russian Roulette. We could have seen the issue and protested. EA's could have created organizations to fight against gain-of-function research. Why didn't we speak every Petrov day about the necessity to stop gain of function research? Organizations like OpenPhil should go through the 5 Why's and model why they messed this up and didn't fund the cause. What needs to change so that we as rationalists and EA's are able to organize to fight against tractable risks that our society takes without good reason?

I don't factor Bayes factors together when I'm on Metaculus either, so that's not really how I reason. If you want them I would be interested in yours for the following pieces of evidence.
How do you get a probability as high as 35% for a natural origin? Can you provide Bayes factors for that?
There's a database for Coronaviruses. We (the international community) funded it to help us for the time when we have to deal with a coronavirus pandemic. The Wuhan Institute of Virology (WIV) took it down in late 2019 and doesn't give it to anyone. Nobody complains about that in a way that brings this in the mainstream narrative even when all those virologists who believe in their field should think that the database is valuable for fighting the pandemic. If it isn't why are we funding that research in the first place?
According to the US government information there was unusual activity in the WIV in October 2019 with at least significantly reduced cell phone traffic and likely also road blocks.
Three people from the WIV seems to went to hospital in November 2019 with flu or COVID-19 like symptoms in the same week.
Huang Yanling who was in the beginning of the pandemic called patient zero was a WIV employee and US government requests who account for what's up with her currently go unanswered.
The security at the WIV was so bad that they asked the US for help in 2018 because they didn't have enough skilled people to operate their biosafety 4 lab safely. Chinese care about saving face, things need to have been bad to get them to tell the US that they didn't have enough people to operate their lab safely.
There are six separate biological reasons of why the virus looks like it came from a lab.
The bats are more then 1000km away from Wuhan. It's quite unclear how they would have naturally infected people in Wuhan.
An amazing amount of effort went into supressing the story, likely with a lot of collateral damage that made us react less well to the pandemic. Google, Facebook and Twitter started censoring in early February and that might have been part of the reason why it took us so long to respond.
As Bret Weinstein said, that given that the virus looks so much like it comes from Wuhan the next likely alternative explantion would be that someone went through a lot of effort and released it in Wuhan to make the WIV look bad. If that would be the case it's however unclear why the WIV doesn't allow outside inspections to clear their name.
If all the information we had was that Huang Yanling who was in the beginning called 'patient zero' was a WIV employee that alone might warrent more then 65%. I mean what are the odds that 'patient zero' for a pandemic caused by Coronavirus is randomly an employee of a lab studying Coronaviruses?
Then a lab studying Coronaviruses with known safety problems?
