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.

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.

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.

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

🔍 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

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.

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.

Advancing the psychology of social class with large-scale replications in four countries - Nature Human Behaviour

Social class is assumed to be associated with many different individual outcomes and behaviours. This Registered Report aimed to replicate 35 key hypotheses from 17 correlational and 5 experimental studies using quota-based or probability samples.

Personality stays mostly the same after moving up in social class, new study suggests

In a long-term study of German youth, first-generation students who attended university became slightly more risk-averse. However, traits like conscientiousness, agreeableness, and openness developed similarly to peers from similar backgrounds who didn’t pursue higher education.

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.
