Ivor Cummins ( @FatEmperor) lists articles he claims shows lockdowns are not effective. The Great Barrington Declaration exploited this list.

This thread will debunk Cummins' claim, while giving some further context.

Potholer54 made a video rebutting Cummins' points, @theresphysics corrected Cummins' misrepresentation of his research, and @dr_barrett made a rebuttal thread as well:

Cummins responded to @dr_barrett's thread with a video that is... ridiculous:


There's a comment thread rebutting Cummin's response video:


I'll summarize some of the thread's points here.

Cummins screws up on endogeneity, by not fully accounting for the fact that lockdowns often occur because COVID-19 deaths/day and cases/day are increasing.

@zorinaq explained this, as have others:

Plenty of papers show lockdowns work. Strangely, Cummins evades them and instead includes many non-peer-reviewed sources in his list. Cummins also pretends a paper was published in the Lancet, when it actually wasn't.

Cummins video then descends into conspiracism about Dr. Ken Rice ( @theresphysics), who's research Cummins misrepresents.

Dr. Rice's research actually shows caution is needed coming out of lockdown:

Next, Cummins discusses a 2009 article from Dr. Marc Lipsitch ( @mlipsitch). The paper is not about lockdowns being ineffective against COVID-19:
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2652751/

Cummins knows this, so he's being deceptive when he includes in a list entitled:

Things get ludicrous when Cummins discusses Belarus at the 10 minute mark in his video.

To Cummins followers:

Many of you like to think you and Cummins are skeptical truth-seekers, who don't fall for disinformation.
So how did you fall for this?

For context:

Belarus is a repressive dictatorship. Many repressive regimes likely fake their COVID-19 statistics to make it look like they're succeeding. So I've been skeptical of Belarus' COVID-19 statistics for months.

But Cummins uncritically accepts Belarus' COVID-19 statistics, since they fit his narrative (Belarus didn't lockdown and its reported stats look fine).

Cummins cites the non-peer-reviewed press piece below to do that. That piece ends as follows:

https://www.bmj.com/content/370/bmj.m3543

So if Cummins read his source, then he should look up excess deaths for Belarus. Yet he probably didn't

But if he's going to a cite a non-peer-reviewed source on this, then I will as well from @hippopedoid on excess deaths:

At this point, sensible people would not trust Cummins, since (at best) he was gullible + biased enough to fall for obvious disinformation.

...Oh, but it gets worse. 🤦‍♂️

Cummins then cites a non-peer-reviewed analysis from PANDA. Yes, *that* PANDA. https://twitter.com/malar0ne/status/1353934042236784640
