In the past 5 decades, the obesity rate in the United States has never gone down two years in a row, paraphrased from the Odd Lots Episode linked above.
Totally astounding. I'd be on that changing over the next two years.
The Sicilian Revolution, the first one of the many revolutions of 1848, was kicked off by a single person putting up flyers in the name of a revolutionary committee that didn't exist.
You could argue that if something this small could kick off a revolution, then it was going to happen anyway... and yet, what if no one else had thought to do it?
Incredibly, the placebo effect is (mostly) not real.
It is a result of statistical confusion. Whenever you have a group with extreme values, they tend to exhibit regression to the mean. Eg. on average, sick people tend to become more healthy over time.
Modern Europe’s total urban population only surpassed the total urban population of the Roman Empire around the time of Isaac Newton, a whole 16 centuries after the ancient peak (which implies that the rate of urbanization was lower, as 17th century Europe had over 100 million inhabitants, a substantially larger population than estimated for the Early Roman Empire, whose population has estimates ranging from 50 to 75 million).
Weirdly, this reminded me of reading Dr. Zhivago. One of the things I'll always remember about that book is the way society deteriorated around Dr. Zhivago.
