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? Image
Nuclear does have less support than other green technologies, but in most places, it still receives net support. Image
This apparently low level of support looks higher when survey participants are asked about their ranked supported for different energy sources. Image
This support increases further if you subset to people who are techno-optimists or tech-neutral when it comes to fighting against climate change. Image
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. Image
Onto the demographics!

In some countries, the old are the most supportive of nuclear. In others, it's the young. Image
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. Image
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. Image
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.Image
Image
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. Image
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. Image
Give the whole report a read, here: radiantenergygroup.com/reports/public…

Where did that human capital go?

After the Counter-Reformation began, Protestant Germany started producing more elites than Catholic Germany.

Protestant cities also attracted more of these elite individuals, but primarily to the places with the most progressive governmentsđź§µImage
Q: What am I talking about?

A: Kirchenordnung, or Church Orders, otherwise known as Protestant Church Ordinances, a sort of governmental compact that started cropping up after the Reformation, in Protestant cities. Image
Q: Why these things?

A: Protestants wanted to establish political institutions in their domains that replaced those previously provided by the Catholics, or which otherwise departed from how things were done. Image

What predicts a successful educational intervention?

Unfortunately, the answer is not 'methodological propriety'; in fact, it's the oppositeđź§µ

First up: home-made measures, a lack of randomization, and a study being published instead of unpublished predict larger effects. Image
It is *far* easier to cook the books with an in-house measure, and it's far harder for other researchers to evaluate what's going on because they definitionally cannot be familiar with it.

Additionally, smaller studies tend to have larger effects—a hallmark of publication bias! Image
Education, like many fields, clearly has a bias towards significant results.

Notice the extreme excess of results with p-values that are 'just significant'.

The pattern we see above should make you suspect if you realize this is happening. Image

Across five different large samples, the same pattern emerged:

Trans people tended to have multiple times higher rates of autism. Image
In addition to higher autism rates, when looking at non-autistic trans versus non-trans people, the trans people were consistently shifted towards showing more autistic traits. Image
In two of the available datasets, the autism result replicated across other psychiatric traits.

That is, trans people were also at an elevated risk of ADHD, bipolar disorder, depression, OCD, and schizophrenia, before and after making various adjustments. Image

Across 68,000 meta-analyses including over 700,000 effect size estimates, correcting for publication bias tended to:

- Markedly reduce effect sizes
- Markedly reduce the probability that there is an effect at all

Economics hardest hit: Image
Even this is perhaps too generous.

Recall that correcting for publication bias often produces effects that are still larger than the effects attained in subsequent large-scale replication studies.Image
A great example of this comes from priming studies.

Remember money priming, where simply seeing or handling money made people more selfish and better at business?

Those studies were stricken by publication bias, but preregistered studies totally failed to find a thing. Image

Neat new article from @Scientific_Bird.

It argues that one of the reasons there was an East Asian growth miracle but not a South Asian one is human capital.

For centuries, South Asia has lagged on average human capital, whereas East Asia has done very well in all our records. Image
It's unsurprising when these things continue today.

We already know based on three separate instrumental variables strategies using quite old datapoints that human capital is causal for growth. That includes these numeracy measures from the distant past.

Image
This makes a lot of sense, too.

Where foreign visitors centuries ago thought China was remarkably equal and literate (both true!), they noticed that India had an elite upper crust accompanied by intense squalor.

Men tend to get more steps in a day!

Sources say...

Yes. Wherever we have large-scale, representatively sampled data, men tend to get a few more steps in compared to women. Image
Step counts tend to vary by area.

For example, New York—thanks to New York City—has the highest average step count.

Colorado—due in part to its selected active, athletic population—also manages a high step count.

You'll also notice that moderate temps mean more steps. Image
What's up with these location effects? Are they causal?

As it turns out, the answer is partially in the affirmative.

That is, some places actually encourage people to walk more!

How do we know? Simple.
