The Report of Stereotype Threat's Demise Has Been Greatly Exaggerated And why I'm feeling a certain way about it

Today Dominic Packer & @jayvanbavel.bsky.social republished @minzlicht.bsky.social's post about "The Downfall of Stereotype Threat" in their widely-read The Power Of Us newsletter. I felt a certain way about that & the evidence presented there & thought I'd respond:

We find that regions with more Ku Klux Klan activity in the 1920s show higher levels of modern White Supremacist activity but, unexpectedly, lower levels of modern implicit and explicit racial bias

New by @maxprimbs.bsky.social et al.

Still trying to get my head around the findings, a bit of a head-scratcher

I love this type of research question & research design, so I'll be sure to dig in.

4-panel cartoon of 2 people and a dog:
Panel 1: Person in green shirt looks apprehensively at the dog and asks the person in blue shirt "Does your dog bite?"
Panel 2: Person in blue shirt replies "No, but it can hurt you in other ways."
Panel 3: in an apparent demonstration of how the dog can hurt you without biting, the dog says to the green shirted person: "Just because you can draw a DAG does not mean that the relationships depicted are causal."
Panel 4: the green shirted person is crying while the blue shirted person and dog look on.

🚨 New paper! Think of a place you feel deeply attached to. When you're in that place, do you feel like your life is more meaningful? New work from @ashleykrause.bsky.social suggests you probably do!

Just accepted at Journal of Environmental Psychology, we find places can give our life meaning 🧡

I spend 1/2 my time asking people to peer review more, & other 1/2 complaining that filthy rich publishers should pay for our labour

These aren't incompatible complaints

Scientists DO need to review more (especially if publishing) Publishers DO need to pay reviewers

One approach to the age-period-cohort problem: Just don’t. Just to cause yourself more problems, you seek for something. But there is no need for you to seek anything. You have plenty, and you have just enough problems. ShunryΕ« Suzuki in a 1971 talk A ...

New blog post about the age-period-cohort identification problem!

In which, for the first time ever, I ask "What's the mechanism?" and also suggest that sometimes you may actually *not* be interested in causal inference.

Basic questions like "how many participants are in the dataset?" can produce surprisingly different answers between analysts.

Results from students in my class in data wrangling in tidyverse, who are good at wrangling but still have to make semi-subjective choices:

What’s a multiverse good for anyway?

Julia M. Rohrer, Jessica Hullman, and  Andrew Gelman

Multiverse analysis has become a fairly popular approach, as indicated by the present special issue on the matter. Here, we take one step back and ask why one would conduct a multiverse analysis in the first place. We discuss various ways in which a multiverse may be employed – as a tool for reflection and critique, as a persuasive tool, as a serious inferential tool – as well as potential problems that arise depending on the specific purpose. For example, it fails as a persuasive tool when researchers disagree about which variations should be included in the analysis, and it fails as a serious inferential tool when the included analyses do not target a coherent estimand. Then, we take yet another step back and ask what the multiverse discourse has been good for and whether any broader lessons can be drawn. Ultimately, we conclude that the multiverse does remain a valuable tool; however, we urge against taking it too seriously.

Causion interface showing a front-door DAG

Causion interface showing a front-door DAG

Played around with Causion by @isager.bsky.social
It's an impressive teaching tool for causal inference... and it also really pretty. Amazing color scheme and slick interface.
Shown below a demonstration of an extended front-door DAG in Causion.

If you do research about research, you really need causal thinking (just like when you do research about anything else really).
