Radiant Energy Group recently published a massive international survey of opinions on nuclear energy.
It's full of some things you might already know, but it also contains some surprises🧵
For example, did you know French and German nuclear support isn't that different?
Nuclear does have less support than other green technologies, but in most places, it still receives net support.
This apparently low level of support looks higher when survey participants are asked about their ranked supported for different energy sources.
This support increases further if you subset to people who are techno-optimists or tech-neutral when it comes to fighting against climate change.
Unfortunately, most people aren't aware about nuclear is exceptionally clean. Even larger numbers think nuclear waste is a major point of worry.
The Simpsons has done incredible damage to the reputation of our best energy source.
Onto the demographics!
In some countries, the old are the most supportive of nuclear. In others, it's the young.
If you've seen other surveys on the demographics of nuclear support this one won't surprise you: men are universally more supportive of nuclear.
If you've seen other surveys on the relationship between science knowledge and nuclear support, this won't surprise you either: the most knowledgeable are (almost) universally the most supportive of nuclear.
Despite being the current best option for providing reliable, low-cost, and clean energy, being concerned about the climate generally predicts less support for nuclear.
When climate concern is represented by nonprofit membership, there's a similar result.
Despite the nuclear industry being aligned with numerous (typically) left-wing goals from protecting the environment to supporting labor unionization and high employee safety standards, it's the economically right wing that's more supportive of nuclear.
There's more in the report, but I'll end this thread on a happy note: globally, there's more support for additional nuclear builds than for additional nuclear shutdowns.
"Without Mohammed, Charlemagne would have been inconceivable."
This quote describes Pirenne's thesis that Antiquity—the period when economic activity concentrated in the Mediterranean—ended because the rise of Islam destroyed the flow of trade across it.
The decline in trade that resulted from differences in faith had profound consequences for the economic geography of Europe.
Byzantine economic activity depended on trade, and it collapsed, whereas the Frankish economy, which was never trade-dependent, transformed.
The Byzantines' minting stalled and the Arabs' and Franks' increased (perhaps partly because they were cut off from one another!), providing each of their states with divergent trends in seignorage revenues and a widening gulf in the ability to fund the government.
Robustness tests are supposed to show a study's results hold up no matter how you reasonably change the specification
But we live in a world with p-hacking, and people p-hack robustness tests
Compared to unshown robustness tests (blue), what we get is suspiciously significant!
This is the distribution of z-values for different tests in economics papers, coupled with the robustness tests their authors presented, and other, plausible robustness tests they didn't.
Clearly people p-hack, and they p-hack tests that are supposed to make us think they didn't
It's sad this is the case. Were it not, it might be useful to get a surprising, marginally-significant result, and then show that it holds up across different permutations of the results
But because the robustness tests shown are selective, their potential utility is unrealized
Let's talk about the glass delusion, the Middle Ages' bout with a mass psychogenic illness marked by people believing they were made of glass.
Glass was a valuable commodity in Europe. It was primarily owned by the noble and well-to-do, and it had a notable purpose in alchemy.
Its perception as the technology of the time was as one that's both fragile and valuable, like the nobility.
Glass was the relatively novel technology people knew, and they knew things could be transmuted into glass. Delusional people also thought transmutation could affect them.
The massive increase in homicides in the last week of May of 2020 started in the days after George Floyd's death.
The Floyd Effect principally refers to the impact of George Floyd's death on homicide numbers in the U.S. through diverse mechanisms, such as reduced cooperation with police, reduced police activity, presence, and willingness to confront potential criminals, and maybe more.
The effect primarily occurred due to an increase in firearm violence that was largely isolated to African Americans. The effect is timed to the
College students make or are forced to make suboptimal choices about the times their classes take place🧵
For students who register for 8AM classes, about a third wake up after class starts, and almost 40% wake up too late to get to class on time.
People's internal rhythms aren't things they just choose, they're somewhat out of their control because they're synced up with day-night cycles.
Consider this, showing the amount of time 8AM class-takers sleep on school days vs weekends (gray), measured through logins at school.
If you compare those 8AM class-takers to 9AM students, you see that the ones who registered for 9AM classes sleep longer, but both sleep similar lengths on weekends.
