Occupational Licensing, Intergenerational Occupational Persistence and Social Mobility We study the relationship between occupational regulation and intergenerational occupational persistence. Using the UK Household Longitudinal Study (2009–2024), we find that individuals are significa...

Why do so many doctors, accountants, and solicitors have parents who did the same profession?

In a new paper with Maria Koumenta (QMUL), we show that occupational regulation increases intergenerational occupational persistence in the UK, thereby reducing social mobility.

📢 New publication!

Together with @dariatisch.bsky.social, I’m happy to share our new article bringing gender into a key methodological debate on how to answer causal questions.

📢 In this Social Forces article, I introduce occupational elitism as a novel measure of social closure: the share of upper-class background workers within an occupation.

Its consequences for earnings stratification can be examined using a social closure theory lens.

Short version: Germany has much bigger motherhood penalties than France, but they are not more socially stratified.

That wasn’t what we expected.

Comparing age-happiness relationships between Japan and Europe Numerous studies have examined the existence of the “well-being paradox,” according to which subjective well-being is stable or even improves in later life despite worsening health and social losses.

New #research into #happiness levels by age compared our #data with the Japanese General Social Survey 🇯🇵.

Takashi Oshio (Hitotsubashi University 🇯🇵) and Satoshi Shimizutani (Nagoya University 🇯🇵) assessed happiness levels in France 🇫🇷, Germany 🇩🇪, Japan 🇯🇵, and the United Kingdom 🇬🇧.

Survey experiments have become a popular methodology among social scientists. Has it been effective?

In POQ, Rauf et al. study the efficacy of 100 survey experiments. Their results show that a majority of hypotheses were not supported.

Just gave my last talk of the year!

2025 was quite packed, I gave talks about:
- the age-period-cohort problem
- making rigorous causal inference more mainstream
- mediation analysis
- marginaleffects
- causal graphs (x10)

With current technology, it is impossible to tell whether survey respondents are real or bots. Among other things, makes it easy for bad actors to manipulate outcomes. No good news here for the future of online-based survey research

I personally think this is a "harder problem" than we care to admit.

So, are you a (social) scientist struggling with this situation? A break between what you _want_ to study (a causal process) and what you feel you _can_ credibly study (a correlation)?

Here are some readings that might help. 👇

I'm facilitating a causal inference reading group next semester for Sociology PhD students. (I will also be learning!) If there are (1) pedagogical articles or (2) empirical examples in soc that you ❤️, will you share in the comments? [And please RT to help me crowd-source!]

Billions of regressions ≠ robustness.

My new PNAS Letter shows how unjustified models can drown out justified ones — and why thoughtful model selection matters👇

Multiverse studies seem doomed to perpetuate a cycle of "look it varies!" "but not that much" "does too!".

Here's another exchange that I had missed.

NO
