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 surprisesđź§µ
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.
Why do identical twins have such similar personalities?
Is it because they're reared together? Is it because people treat them alike due to their visual similarity?
Nope! Neither theory holds water.
Despite looking as similar as identical twins and being reared apart, look-alikes are not similar like identical twins are. In fact, they're no more similar than unrelated people.
This makes sense: they're only minimally more genetically similar than regular unrelated people.
The other thing is that twins reared apart and together have similarly similar personalities.
In fact, there might be a negative environmental effect going on, where twins reared together try to distinguish their personalities more!
Smart people tend to earn higher educations and higher incomes, and to work in more prestigious occupations.
This holds for people from excellent family backgrounds (Utopian Sample) and comparing siblings from the same families!
This is true, meaningful, and the causal relationship runs strongly from IQ to SES, with little independent influence of SES. Just look at how similar the overall result and the within-family results are!
But also look at fertility in this table: quite the reverse!
The reason this is hard to explain has to do with the fact that kids objectively have more similar environments to one another than to their parents.
In fact, for a cultural theory to recapitulate regression to the mean across generations, these things would need to differ!
Another fact that speaks against a cultural explanation is that the length of contact between fathers and sons doesn't matter for how correlated they are in status.
We can see this by leveraging the ages parents die at relative to said sons.
The internet gives everyone access to unlimited information, learning tools, and the new digital economy, so One Laptop Per Child should have major benefits.
The reality:
Another study just failed to find effects on academic performance.
This is one of those findings that's so much more damning than it at first appears.
The reason being, laptop access genuinely provides people with more information than was available to any kid at any previous generation in history.
If access was the issue, this resolves it.
And yet, nothing happens
This implementation of the program was more limited than other ones that we've already seen evaluations for though. The laptops were not Windows-based and didn't have internet, so no games, but non-infinite info too
So, at least in this propensity score- or age-matched data, there's no reason to chalk the benefit up to the weight loss effects.
This is a hint though, not definitive. Another hint is that benefits were observed in short trials, meaning likely before significant weight loss.
We can be doubly certain about that last hint because diabetics tend to lose less weight than non-diabetics, and all of the observed benefit has so far been observed in diabetic cohorts, not non-diabetic ones (though those directionally show benefits).
