is an excellent scientist and a responsible professional. She likely read the paper more carefully than most. She grasped some of its strengths and weaknesses that are not apparent from a cursory glance. Below, I will mention a few points some may have missed.

I've recently come across a disinformation around evidence relating to school closures and community transmission that's been platformed prominently. This arises from flawed understanding of the data that underlies this evidence, and the methodologies used in these studies. pic.twitter.com/VM7cVKghgj

More from Science
1/ Automobiles and Intake Fraction. Since cars are back in the news I thought I would retweet this model result I offered in early April 2020. I focused only on 1 micron particles & accounted for windows completely closed & cracked slightly open.
2/ Related air exchange rates were based on experimental results in literature for mid-sized sedans. Particle deposition to indoor surfaces were accounted for, as the surface to volume ratio in a 3 m3 cab is large. An important outcome was the intake fraction (IF)
3/ Here, IF is the number of particles (or virions in collective particles) inhaled by a receptor DIVIDED BY the number or particles (or virions in collective particles) emitted by an infector.
4/ Integrated over the two hour drive (in this example) the IF for all windows closed & a receptor at rest is 0.08 (8% of what comes out of the infectors respiratory system ends up in the respiratory system of the receptor). 8%! That is a very high intake factor.
5/ With additional ventilation from cracking a window open drops the IF to 0.012 (1.2%) still relatively high. Can get lower by opening more windows.
Simulation: Riding in car for 120 min w/ infected passenger who seems fine other than a cough every few mins. (1) a lot of SARS-CoV-2 virus (in fine aerosol particles) accumulation in car cabin w/ windows closed; (2) cracking window open slightly = dramatic reduction. #COVID19 pic.twitter.com/bCmrmnLUPG

So it turns out that an organization I thought was doing good work, the False Memory Syndrome Foundation (associated with Center for Inquiry, James Randi, and Martin Gardner) was actually caping for pedophiles. Uhhhh oops?
Since this, bizarrely, turned out to be one of my longest videos ever (??) here's a quick thread to sum it up for those of you like myself with short attention spans. 1/10
In the '90s the False Memory Syndrome Foundation was founded to call attention to the problem of adults suddenly "remembering" child abuse that never actually happened, often under hypnosis. Skeptics like James Randi & Martin Gardner joined their board. 2/10
A new article reveals that the FMSF was founded by parents who had been credibly and PRIVATELY accused of molestation by their now-adult daughter. They publicized the accusation, destroyed the daughter's reputation, and started the foundation. 3/10
The FMSF assumed any accused pedo who joined was innocent, saying "We are a good-looking bunch of people, graying hair, well dressed, healthy, smiling; just about every person who has attended is someone you would surely find interesting and want to count as a friend" 😬 4/10
