So glad to share this new episode of Knitting Networks, featuring Tom A. B. Snijders, a mentor for many of us and one of the most inspiring minds in our field. ๐ŸŒ
A conversation about bridges between mathematics, sociology, and network modelling.

In this episode, we discuss how culture and cognition shape network ties, the value of data science, and how sociology can bridge structure and meaning.

Socio-cognitive networks between researchers: Investigating scientific dualities with the group-oriented relational hyperevent model Understanding why researchers cite certain works remains a key question in the study of scientific networks. Prior research has identified factors sucโ€ฆ

5/n Curious how social and cognitive structures shape scientific knowledge?

4/n ๐Ÿ“Œ Highlights:
โ€“ Citations favor recent & cognitively consistent work
โ€“ Tight coauthoring groups are co-cited more often
โ€“ Citation behavior is not just individual: itโ€™s embedded in collaboration networks

3/n Our data: Chilean astronomers (2013โ€“2015)
๐Ÿ”ง Method: Relational Hyperevent Model (captures group-based events like coauthoring and citing)
๐Ÿ’ก Key insight: Coherent groups of coauthors are more likely to be co-cited together โ€” social structure reinforces cognitive links.

2/n We ask: Why do researchers cite what they cite?
Beyond content relevance, we consider how social ties (coauthorship) and cognitive continuity shape citation choices.
Think of citation as the tip of a longer collaborative and intellectual process.
