Short thread: 1/N

Moral judgments in online discourse are not biased by gender Scientific Reports - Moral judgments in online discourse are not biased by gender

🚨Are moral judgements biased by the gender of the subject?
We find *no* direct effect when looking at Reddit!

Our causal study design is based on carefully matching similar situations that people with different genders experience (and share).

Synergistic Signatures of Group Mechanisms in Higher-Order Systems A new study of complex systems supports a growing trend that focuses more on analyzing a system's collective behavior rather than on trying to uncover the underlying interaction mechanisms.

How do group interactions shape the world? Collective behavior isn’t just one-to-one—it’s synergy. New research by T. Robiglio, F. Battiston & colleagues shows how higher-order interactions drive emergent effects.
