Statistics Canada is doing a pilot study of a mobile-device-based wellbeing-survey and they're recruiting respondents through the Very Scientific method of.... emailing everyone who's ever emailed their technical support desk.
Extremely strong selection there for "disgruntled data analysts" so that's gonna be a WILD pilot study.

I have of course signed up and downloaded the app and am PSYCHED to be a respondent in another survey.
I'm a longitudinal panelist in two surveys, I've gotten ACS AND CPS (!!), and I'm a standing panelist in multiple "big survey company" databases, and because I very reliably take the surveys, my personal traits are wildly overrepresented in studies of Americans.
Basically if you've used any data from Gallup or Qualtrics in the last 4 years, you used a response from me. I take *all* the surveys.
And I actively seek out ways to wriggle my way into survey databases. Still working on a few high value targets I'd like to get into!
But really there's no better way to learn about survey methods and what works and what doesn't than just participating in huge volumes of surveys from various companies on a wide range of topics.
Anyways the reason I know how Statistics Canada recruited is I've contacted their technical support folks on multiple email addresses and I got invitations on both. Only gonna use one (though, uh, TEMPTATION, wow), but still seems like that's their sampling frame.

Good question!

Mongolia's demography is absolutely fascinating and it's worth taking a closer look in regional comparison!
To start with, this is not my first foray into Mongolia commentary. It's an amazing country I've tweeted about a lot because I'm lowkey obsessed with it. It's basically the Kentucky of Asia.
You can read some of my takes on the plight of Mongols in China here as well. The cultural commonality and difference between ethnic-Mongols in China and Mongolians is a fascinating divide without clear parallel anywhere in the world!

This study of long COVID in Norway has a nice design: PCR tests, long follow-up, large sample, and a plausible mechanism for identifying cases: a huge pre-existing panel survey using frequent mobile-device questionnaires. medrxiv.org/content/10.110…
My only real critique is that while they do have about 80,000 people in the sample, it's Norway, so they only managed to find about 800 COVID cases. lol. problems of low attack rate!
But, among those 800, they found that no single symptom of "long COVID" occurred among more than 22% of infected people. The most common symptoms among COVID+ people were loss of taste/smell and fatigue. Loss of taste was NOT correlated with other cognitive symptoms.

Luckily, this can be simply "solved" from a statistical approach by just deleting the option "Christian" from the survey.
When you have an option that is confusing respondents, there's a solution! Delete it! Force them to choose between the empirically meaningful options.
Also, the actual best way to survey religion is to ask people, "Think about the place you most often worship. What is its name?" and then to do a follow up, "Do you happen to know what religion this place of worship is associated with?" then give religion options.

I like David French but this is clearly wrong.
There has been progress on racial justice, yes: but most of the progress occurred while religiosity was still very high and fairly stable. As religiosity has declined, progress on racial justice has clearly faltered, and we're now in a place were it's not even clear...
What anybody means by a phrase like "progress on racial justice." Without a shared pre-political moral landscape, statements like that are meaningless, and so unsurprisingly political discourse around them becomes irresolvable.

Quebec COVID update: Back when I projected this wave would just never generate the deaths and hospitalizations the government worried about, I made 3 scenarios for ICU cases. One assumed Case-->ICU ratios returned to historic wave ratios. One assumed they flatlined. One fell.
For January 8, the latest data, my low forecast suggested there would be 208 ICU cases. My mid forecast suggested 333 ICU cases. And the high forecast, the one the government is basically treating as "what is going to happen," was 795.
In reality, on January 8, there were 257 ICU cases: between my low and mid scenarios. So it continues to be the case that Quebec's wave is generating far fewer ICU cases per official positive case than prior waves.

What is the best empirical evidence that therapy actually improves mental health?

I am struggling to find anything credible.
This meta-analysis of 147 studies seems to suggest p-hacking is very common, publication bias is huge, and even with that the typical effect of therapy vs. care-as-usual is clinically insignificant. pubmed.ncbi.nlm.nih.gov/21770842/
This more recent one specifically on CBT for adult depression suggests that CBT has been wildly overrated by creative research practices. journals.sagepub.com/doi/abs/10.117…
