In my 1st study, I examine how the racial wealth gap varies by skin tone, a factor that shapes the extent to which people are perceived to fit a racial category. I not only find evidence of skin tone gaps but I also show that these gaps grow over time:

"How to detect heterogeneity in conjoint experiments"

https://t.co/slj4iy3a8p

[John B. Holbein @JohnHolbein1]

If you run conjoint experiments, you need to read this.

Most conjoints estimate average effects for each attribute.

But what if the effect of one attribute depends on the others?

This new paper introduces a data-adaptive conjoint design that hunts for heterogeneity:

Where does a focal attribute matter most (or least)—depending on context?

The authors show that U.S. adults weigh immigrants’ education very differently depending on background—sometimes it matters a lot, sometimes not at all.

I’ve only run a few conjoints, but I’ve always wondered:
Why don’t more designs try to surface this kind of interaction?

Very cool. Very important.

🚨New paper (link in reply)🚨

Are we underestimating AI use in self-report surveys?

YES, by as much as 30 percentage pts.

We find 60% self-reported vs. truth closer to ~90% (!)

Why? Social desirability bias, people embarrassed/worried to admit AI use, so they underreport.

NEW PUB ALERT!!! 🚨 My paper shows how East Asian women in relationships w White, Black, and South Asian men construct racialized masculinities in romantic contexts. I reveal how these processes can both challenge and reinforce gender and racial hierarchies @SREJournal #Sociology

How many people go to church weekly?

Surveys say it's about 1 in 5 Americans.

Cell phone tracker data say it's actually closer to 1 in 20 Americans.

Fascinating!

Excellent new paper on depth of learning from LLMs. Studies using large samples show LLMs like ChatGPT leads to shallower learning compared to using more traditional means like web search. When people rely on AI-synthesized answers, they develop less knowledge depth.🧵

Flexible Covariate Adjustments in Regression Discontinuity Designs

"In this paper, we propose a novel class of estimators that use such covariate information more efficiently than existing methods and can accommodate many covariates."

Donut Regression Discontinuity Designs

"While the donut approach is very popular in empirical practice, it is generally carried out in a heuristic fashion without much supporting statistical theory."

Excited that this paper is out! @p_fomby and I describe nonresident parent wealth among children in the US using the @umpsid. We show that children likely have access to this wealth, and that it matters for their educational attainment in young adulthood.
