📢 In a new study in #SocialNetworks, David Kretschmer and I examine how religious #segregation in #adolescent #friendship networks develops from 11 to 17 📈, focusing on #gender 🚹🚺. We find an increase in in‑group friends only among highly religious #Muslim girls 💡.

1/4 📢 New paper in PSPB with Andreas Flache!

How do attitudes & behaviors spread?
#SocialInfluence among #adolescents isn’t just passed from friend to friend — it also flows through group norms. Both channels shaped academic drive, #prejudice, #religiosity.

BREAKING: new study just dropped that shows compelling evidence that cell phone bans cause student grades to modestly increase.

Grade increases are largest among low performing students.

Saddened by news of Tom Lehrer's passing. We remind ourselves of history's most effective criticism of quantitative sociology.

If your descriptive figures and your model tell different stories, trust the figure. (And maybe rethink the model.)

Sometimes, a descriptive figure is worth more than a thousand model coefficients: the importance of data description in social research
Many social research questions aim at understanding relationships between different phenomena, and increasingly complex multivariate statistical models are often employed to address these questions...

Statement of @isa-rc28.bsky.social on the decision of @isa-sociology.org to suspend the Israeli Sociological Association
Decision by the International Sociological Association (ISA) to suspend the Israeli Sociological Society (ISS) as a collective member

 
Dear RC28-community,
 
As members of the ISA-RC28, we are deeply committed to the values of international scholarly collaboration, academic freedom, and critical engagement. It is precisely because of this commitment that we feel compelled to express our concerns about the decision to suspend the Israeli Sociological Society (ISS) as a collective member.
 
While we share the ISA’s commitment to human rights and solidarity with people affected by violence, we believe that professional scholarly organizations should not be treated as representatives of their governments. We are aware that boycott is a means of applying pressure on governments and societies; however, in the field of academia, it can endanger the space needed for rigorous and principled academic dialogue. Academic boycotts shut down debate and silence diverse voices—precisely the opposite of what academia should represent. Moreover, the ISS is deeply committed to democratic values, human rights, and academic freedom. Over the past four years, many of its members – including those affiliated with ISA-RC28 – have actively worked to document, critique, and stand against their government’s actions and policies. The ISA’s decision not only weakens these progressive efforts on a broader scale, but also has real, personal, and professional consequences for members of our community.
 
RC28 has a proud tradition of supporting sociologists who were repressed for their progressive views and actions – for example, in Czechoslovakia and Hungary under Soviet rule. In that spirit, we should support, not boycott, the progressive forces within Israel and elsewhere.
 
Questioning the ISA’s decision does not imply support for the actions of the Israeli government, nor does it diminish the destruction, death, and human suffering in Gaza. Rather, it reflects a principled belief that academic boycotts undermine the values of academic freedom, open dialogue, and international scholarly collaboration, and should not be used as a response to governmental actions.
 
We respectfully urge the ISA Executive Committee to reconsider this decision.
