Say you’ve got very good causal IDENTIFICATION. Can you say you have causality, can make a causal general claim, and can say what “THE causal effect” is?

NO

Gendered Expectations for College Applications: Experimental Evidence from a Gender Inegalitarian Education Context - Research in Higher Education In Japan, the gender gap in attendance at 4-year universities is narrowing, yet significantly fewer women apply to selective colleges. A growing body of literature suggests that gendered expectations ...

This paper, published in Research in Higher Education, examines how gendered expectations and stereotypes contribute to persistent gender disparities in selective college applications in Japan. link.springer.com/article/10.1...

The regression table examines factors influencing daily housework hours for women and men, highlighting key findings: - **Female Interviewer:** Women spend more time on housework with a female interviewer, increasing the gender gap. - **Paid Work Time:** More paid work reduces housework time for both genders, more so for men. - **Income:** Higher income correlates with less housework for both. - **Marital Status:** Married women do more housework; married men do less. - **Children:** Having children increases housework for both, with significant effects across all child age groups. - **Interview Length:** Longer interviews slightly increase men's housework time. The model explains 16.7% of the variance for women and 9.09% for men, based on 18,965 individuals and 110,544 observations. (Summarized by mistral)

🚨 Are young women becoming more left-wing & young men more right-wing?
We analyzed 32 European countries (1990–2023).
📊 Some show growing gaps—others don’t.
📊 Gaps tend to be bigger where gender equality is higher.

"Simpson's gender-equality paradox" surely deserve some award for best title 👑
The gender-equality paradox seems really central to some narrative people have constructed (and successfully sold). I absolutely wouldn't be surprised if it turned out 100% confounding.>

Thanks to everybody who chimed in!

I arrived at the conclusion that (1) there's a lot of interesting stuff about interactions and (2) the figure I was looking for does not exist.

So, I made it myself! Here's a simple illustration of how to control for confounding in interactions:>
