Normally I enjoy the high standards of journalism in @guardian . Not today as disappointed with misleading headline that suggest infections are spreading fastest in children. It'll worry parents/teachers & I doubt most readers will unpick the

Misinterpretation of surveillance data is a serious issue. Surveillance data needs to come with a warning label - Open to biases - interpret with caution! Some may not realize that surveillance often does not measure all infection, it's a proxy for actual disease incidence.

The science shows us that most disease transmission does not happen in the walls of the school, but it comes in from the community. So, CDC is advocating to get our K-5 students back in school at least in a hybrid mode with universal mask wearing and 6 ft of distancing. https://t.co/dfvJ2nl2s4

Preprint of Welsh study studying staff-pupil #SARSCoV2 infections in schools between Aug-Dec'20. They report total number of infected staff & pupils within a school following re-opening wasn't associated with an increased subsequent risk of testing positive in staff or pupils.1/ https://t.co/w8pBpxbz3b

Study in @PNASNews of COVID19 aerosol generation:
— Andrew Lee (@andrewleedr) February 13, 2021
- 18% of subjects accounted for 80% of exhaled aerosol
- significant correlations were observed between exhaled aerosol, age, & BMI
- all subjects <26 y of age & all subjects under 22
BMI were low spreaders of exhaled bioaerosol https://t.co/eAkTiKDbyk

And we know symptomatic persons shed more virus. So it follows that an adult is more likely to infect a child than the other way.

8. Back to the role of community transmission. The CDC's focus on this is consistent with our own modeling work. Keeping transmission down in the community is the best way to keep it down in the schools. Figure from v.1 of our paper at https://t.co/WLVXv8hYcg pic.twitter.com/AyKKW3bfEH

I have seen some repeated assertions about the evidence on #COVID19, children and schools recently which sound convincing, but unfortunately are false

It is a sensitive and important topic, which is important to get right

Our preprint on the impact of reopening schools on reproduction number in England is now available online: https://t.co/CpfUGzAJ2S. With @Jarvis_Stats @amyg225 @kerrylmwong @KevinvZandvoort @sbfnk + John Edmunds. NOT YET PEER REVIEWED. 1/
We used contact survey data collected by CoMix (https://t.co/ezbCIOgRa1) to quantify differences in contact patterns during November (Schools open) and January (Schools closed) 'Lockdown periods'. NOT YET PEER REVIEWED 2/
We combined this analysis with estimates of susceptibility and infectiousness of children relative to adults from literature. We also inferred relative susceptibility by fitting R estimates from CoMix to EpiForecasts estimates(https://t.co/6lUM2wK0bn). NOT YET PEER REVIEWED 3/
We estimated that reopening all schools would increase R by between 20% to 90% whereas reopening primary or secondary schools alone would increase R by 10% to 40%, depending on the infectiousness/susceptibility profile we used. NOT YET PEER REVIEWED 4/
Assuming a current R of 0.8 (in line with Govt. estimates: https://t.co/ZZhCe79zC4). Reopening all schools would increase R to between 1.0 and 1.5 and reopening either primary or secondary schools would increase R to between 0.9 and 1.2. NOT YET PEER REVIEWED 5/

Working on a newsletter edition about deliberate practice.
Deliberate practice is crucial if you want to reach expert level in any skill, but what is it, and how can it help you learn more precisely?
A thread based on @augustbradley's conversation with the late Anders Ericsson.
You can find my complete notes from the conversation in my public Roam graph:
https://t.co/Z5bXHsg3oc
The entire conversation is on
The 10,000-hour 'rule' was based on Ericsson's research, but simple practice is not enough for mastery.
We need teachers and coaches to give us feedback on how we're doing to adjust our actions effectively. Technology can help us by providing short feedback loops.
There's purposeful and deliberate practice.
In purposeful practice, you gain breakthroughs by trying out different techniques you find on your own.
In deliberate practice, an expert tells you what to improve on and how to do it, and then you do that (while getting feedback).
It's possible to come to powerful techniques through purposeful practice, but it's always a gamble.
Deliberate practice is possible with a map of the domain and a recommended way to move through it. This makes success more likely.

I just finished Eric Adler's The Battle of the Classics, and wanted to say something about Joel Christiansen's review linked below. I am not sure what motivates the review (I speculate a bit below), but it gives a very misleading impression of the book. 1/x
The meat of the criticism is that the history Adler gives is insufficiently critical. Adler describes a few figures who had a great influence on how the modern US university was formed. It's certainly critical: it focuses on the social Darwinism of these figures. 2/x
Other insinuations and suggestions in the review seem wildly off the mark, distorted, or inappropriate-- for example, that the book is clickbaity (it is scholarly) or conservative (hardly) or connected to the events at the Capitol (give me a break). 3/x
The core question: in what sense is classics inherently racist? Classics is old. On Adler's account, it begins in ancient Rome and is revived in the Renaissance. Slavery (Christiansen's primary concern) is also very old. Let's say classics is an education for slaveowners. 4/x
It's worth remembering that literacy itself is elite throughout most of this history. Literacy is, then, also the education of slaveowners. We can honor oral and musical traditions without denying that literacy is, generally, good. 5/x
As someone\u2019s who\u2019s read the book, this review strikes me as tremendously unfair. It mostly faults Adler for not writing the book the reviewer wishes he had! https://t.co/pqpt5Ziivj
