A teachable moment for Bayesian reasoning – when one study finds a result that's massively different than all the others, and, moreover, conflicts with what we know about the science, there's a pretty good chance it's either a fluke or it's wrong.
The Israeli estimate of relatively high immune escape from Delta that a lot of you were freaking out about now looks like it was the result of sloppy statistical analysis. https://t.co/F5sHsJDFF1

More from Covid
Breaking—UK scientists just reported a case-control study that the mutated UK 🇬🇧B.1.1.7 variant is not associated w/ more severe #COVID19— “found no significant differences in hospital admissions and case fatality at 28 days, & occurrence of reinfections”, says @mvankerkhove
2) That said, the new UK mutated strain is a more transmissible (contagious) variant. Keep transmissibility and illness severity separate. They are two different things. Don’t get them confused.
3) The new UK variant severity study is included in today’s WHO report, to be released soon this afternoon according to WHO sources. Waiting for it to drop. I’ll keep folks posted on the details.
4) Update: here is UK Technical report on #SARSCoV2 variant of concern (B.1.1.7) in 🇬🇧 with prelim findings from their case-control study of no increased severity for the new variant that I reported yesterday.
5) Also keep in a mind that a virus that spreads faster (more contagious) yields much worse total outcomes than a virus that is just merely more severe.
All things equal, a new mutated variant that is more contagious & no more severe is worse. And that is what we now have.

Why a SARS-CoV-2 variant that's 50% more transmissible would in general be a much bigger problem than a variant that's 50% more deadly. A short thread... 1/

The entire discussion around Facebook’s disclosures of what happened in 2016 is very frustrating. No exec stopped any investigations, but there were a lot of heated discussions about what to publish and when.
In the spring and summer of 2016, as reported by the Times, activity we traced to GRU was reported to the FBI. This was the standard model of interaction companies used for nation-state attacks against likely US targeted.
In the Spring of 2017, after a deep dive into the Fake News phenomena, the security team wanted to publish an update that covered what we had learned. At this point, we didn’t have any advertising content or the big IRA cluster, but we did know about the GRU model.
This report when through dozens of edits as different equities were represented. I did not have any meetings with Sheryl on the paper, but I can’t speak to whether she was in the loop with my higher-ups.
In the end, the difficult question of attribution was settled by us pointing to the DNI report instead of saying Russia or GRU directly. In my pre-briefs with members of Congress, I made it clear that we believed this action was GRU.
The story doesn\u2019t say you were told not to... it says you did so without approval and they tried to obfuscate what you found. Is that true?
