People in some places in the US have more long ties — ties between people without mutual contacts. This is a map from our newly published paper: pnas.org/doi/10.1073/pn… Why does this matter? How do people end up with these different network structures? 🧵
$Fraction of long ties, measured across counties in the United States, after controlling for average degree. The adjusted (residualized) fraction of long ties across administrative units in each country is binned into 10 deciles, with lower values shown in purple and higher values shown in green. Administrative units with less than 200 Facebook users sufficiently active over the measurement period or with less than 500 individuals are shown in white.$

Why not require 10,000 hours? Anyone arguing for less than 10,000 hours has blood on their hands. It can be so hard to reverse escalating training and safety regulations.

Sen. Kyrsten Sinema is holding up a major bill unless it includes her proposal to require less training for airline pilots. Sen. Tammy Duckworth, an ex-pilot, says Sinema will have 'blood on her hands' if it passes. Why would anyone argue for less training for pilots? Thread.

When asked to draw a regression line, my experience is people draw something closer to the PCA line.

That WhatsApp is down (along with FB & Instagram) is hugely impactful globally, disrupting a lot of one-to-one and group messaging, but also payments and calling. This is a clear illustration of the value of decentralization and robustness in key communication infrastructure.
