There's 3 days left in the @Kickstarter for the audiobook of my upcoming anti-finance finance thriller about #SiliconValley scams, *Red Team Blues*. #Audible refuses to carry my audiobooks because they're #DRM free. Crowdfunding makes them possible!

Is antitrust anti-labor? tl;dr: no.

1/3 This thread sets out a very important and basic point about diagnostic #tests. As #COVID19 cases decline, a higher % of positive results will be false positives. Big issue for #schoolsreopeninguk

2/3 @educationgovuk needs to state clear #exitstrategy for #covid19 testing in #schools to retain trust in a system that was always going to be fragile.
3/3 This will become an issue first in grammar schools and leafier boroughs where homes are less crowded, more #Zoomocrat educated parents. A guide to basics on #falsepositive #COVID19 tests here. #schoolsreopeninguk jackiecassell.com/moonshot-moons…
1/ Here's the latest chapter in my #COVID19 drama.
On Saturday, I tested POSITIVE on a #PCR test.
Was I reinfected?

2/ As some of you might recall, I had a brutal case of #COVID19 in the fall. I spent 17 days hospitalized at @NYULangone, including almost a week in the ICU on a ventilator.

3/ But the idea of having #COVID19 again surprised me, for a number of reasons.
First, reinfection is rare. And I was tested at the same time for #COVID antibodies, and I was still positive.

So not so much a #ContactTracing app as a feature-creeping Christmas tree?
One thing about tech that's successful is that it is ultimately successful because it performs the core function it (cl)aims to provide well.
#efficacious ≠ #effectiveness

In case you're wondering, "Detection rate" refers to detecting other #phones with the app installed, not the #virus:
The #FalseNegative rate is the amount of times the app incorrectly reports a contact as 'non-infectious' when in fact it is / could be...

...and the #FalsePositive rate is how often the app incorrectly reports a contact as 'infectious' when it's not, i.e. a #FalseAlarm.
Basically, what these #ErrorRates tell us is that #Bluetooth ranging is HARD!

"..the positive predictive value of the active screening was only 19.67%, in contrast, the false-positive rate of positive results was 80.33%.
"..the positive predictive value of the active screening was only 19.67%, in contrast, the false-positive rate of positive results was 80.33%.
"The multivariate-probabilistic sensitivity analysis results supported the base-case findings, with a 75% probability for the false-positive rate of positive results over 47%...
Conclusions: In the close contacts of COVID-19 patients, nearly half or even more of the 'asymptomatic infected individuals' reported in the active nucleic acid test screening might be false positives.
