So nice to have you! It was a great talk!
To reduce alternative explanations, we take several precautions: student- and school-level controls (e.g., students' problematic behavior), comparisons within countries, and many robustness checks. We hope this work contributes to the literature on structural obstacles to educational inequality.
Key finding:
📉 In schools with more inclusionary teacher attitudes toward immigration, first-generation immigrant students close a substantial share of the achievement gap, with performance differences roughly equivalent to one year of schooling relative to less inclusive schools.
New research out with Eva Green & Nicolas Sommet! 🧠📊 We investigated whether inclusive teachers’ immigration attitudes (school-level) are linked with narrower academic gaps between immigrant and non-immigrant students across PISA data from 7 countries. 📎 www.anatoliabatruch.com/_files/ugd/3...
No meta-analytical effect of economic inequality on well-being or mental health

Huge thanks to everyone who made this project possible 🙏
We look forward to seeing more theory-refining research on social class and inequality with diverse samples.

So what do we conclude?
Our findings challenge a core assumption in social class psychology:
Rather than being more self-focused, individuals from higher social classes appear to have enough resources to be oriented toward both self and others.
6/
Hypotheses based on broad contrasts—e.g., higher-class = self-focused vs. lower-class = other-focused—replicated less reliably.
The “self vs. other orientation” model needs adjusting.
5/
We explored what kinds of hypotheses were most likely to replicate.
✅ The strongest support was for those grounded in how social class shapes people’s experiences of constraints, uncertainty, and status.
4/
Some surprises:
📉 When an effect replicated in one country, it often did so in others
😮 Higher-class individuals reacted positively to reduced individuation (i.e., making them feel less unique)
🤝 Little evidence they are less prosocial or more unethical
3/
🔍 Key findings:
✅ ~50% of effects replicated
✅ Results were consistent across different social class measures
✅ Effects were often stronger for those who:
• identify more with their class
• justify the social system
• live in more unequal areas
2/
We replicated 22 theoretically-relevant studies (17 correlational, 5 experimental) across the US, France, Switzerland, and India (N = 33,536).
We tested 35 hypotheses spanning:
🧠 Self-concept
🫂 Relationships
💭 Cognition
💬 Emotion
🎯 Behaviour
🧮 Decision-making

🚨 New article out!
How robust is the psychology of social class?
Together with Nicolas Sommet and @frederiqueautin.bsky.social, we conducted large-scale replications of 35 hypotheses across four countries.

Thanks for the shout-out!

A Registered Report by Batruch et al aimed to replicate 35 key hypotheses from 17 correlational and five experimental studies using quota-based or probability samples from the U.S., France, Switzerland, and India.
Personality stays mostly the same after moving up in social class, new study suggests
A group of college students sit together in a library, working on a project.
New #SPPS research finds that upward educational mobility (being the first in your family to attend college/university) could lead to changes in risk-taking behavior, but not broader personality changes.
