We present a simple argument using Promise Theory and dimensional analysis for the
Dunbar scaling hierarchy, supported by recent data from group formation in Wikipedia …

In many group‐living animals, survival and reproductive success depend on the formation of
long‐term social bonds, yet it remains largely unclear why particular pairs of groupmates …

We introduce a novel procedure to assess the goodness of fit in relational event models.
Building on existing auxiliary variable approaches developed in network modelling, the …

Extensive research has investigated the relationship between the social environment and
cognition, suggesting that social complexity may drive cognitive evolution and development …

We present an argument (for a cross disciplinary audience) to explain the Dunbar scaling
hierarchy for social groups. Our analysis is based on the Promise Theory of trust, and basic …

Choosing the right partners can mean the difference between success or failure at a
cooperative task. Several studies in captivity have explored the extent to which animals can …

Collection of large behavioral data-sets on wild animals in natural habitats is vital in ecology
and evolution studies. Recent progress in machine learning and computer vision, combined …

The need to maintain strong social bonds is widely held to be a key driver of cognitive
evolution. This assumes that the maintenance of strong bonds is a stable trait that is …

Social animals often form differentiated social relationships with conspecifics. Developing
closer partnerships with some than others can facilitate cooperative interactions in which …

Social tolerance is crucial in facilitating the evolution of cooperation and social cognition, but
it is unknown whether animals can optimise their social tolerance through learning. We …
