I agree that the paper is not devoted to the JNO paper exclusively. Although, it features the flawed paper very non-critically.
There is no criticism of the design and assumptions of the paper there, only an endorsement from @TanmoyDasLala saying the paper is "fairly robust"

The technical criticisms are interesting and if you publish a paper with your own alternative calculations I'd be very happy to see it. I'm even more interested in research showing how to avoid this catastrophe by reconnecting youth back to high school and college.

The "technical criticisms" revert the sensational results of the paper 180 degrees! We provide "alternative calculations" showing how critical the errors in the JNO paper are.https://github.com/ikashnitsky/pppr-jamano …

The main problem with "alternative calculations" – there is no was to make sense out of this awful paper. The idea that a couple of months of schooling loss can be converted in YLL is beyond ridiculoushttps://twitter.com/ikashnitsky/status/1328121864628166656 …

I guess I don't understand why it's a *ridiculous* assumption; if you agree that educational attainment is *related* to life expectancy, why wouldn't a shock to one affect the other? Even if it's not a one-to-one correspondence.

Even if a causal relationship is established (and upon careful check even of the referenced papers, there is very little effect) – it's a lot of a stretch to translate one into the other.https://twitter.com/ikashnitsky/status/1328121891727544320 …

But even comparing YLL due to the already happened c19 deaths to the counterfactual longevity of kids – effectively assuming no changes in baseline age-specific death rates for the rest of their lives... Just ridiculous

Anya, I'm open to talk more and explain in details is you are genuinely interested.

The JAMA study has many limitations (as they acknowledge). There are also some gaps in their assumptions. But if we’re inserting personal opinion here, I wouldn’t go so far as to call a YLL computation “ridiculous.” The final numbers may be lower, and some effects may be offset.

The final numbers in the paper are largely based on the assumption that every year of schooling reduces your risk of death at all ages by 25%, which they calculated by extracting the wrong numbers from some studies on schooling and mortality

Correcting just this issue - indeed correcting just one transcription error - completely reverses the results of the paper, showing that school closures cost far LESS YLL than COVID-19 (ignoring the other mistakes)

And when I say error, it's really very simple - the study in question said that each year of schooling reduced your risk of death by "about 10%" but the authors said that this paper showed a reduction of 35%
