Some background from Lauren Ancel Meyers @meyerslab about the #epidemiology modeling community's efforts to produce #pandemic projections for the @CDC — first about #influenza and then, suddenly and with the models incomplete, pivoting to #COVID19: 
Aggregate data from travel in and out of #Wuhan in early 2020. To infer the pace of the #epidemic, @meyerslab and colleagues used info on timing & location from first cases in other areas, travel volume to/from Wuhan, and gave an early doubling rate for #COVID19:
"Explosive Proofs of Mathematical Truths"
In just a moment, we'll start live coverage of @SimonDeDeo's SFI Seminar-by-Zoom on a data science study of the epistemic structure of actual proofs.
(Seminar not streamed, but recording will be shared soon.)

Theodor Adorno proposed that political preferences are consequences of the kind of explanations people prefer — individual or systemic.

4 Principles of Collective #Computation:
1 Ground truth (objective reality)
2 Effective ground truth (what we agree on, whether or not it is accurate)
3 #Information can be collectively encoded in #networks
4 Outputs are a product of collective dynamics
