Henrich et al. provide a compelling argument about a bias in the behavioral sciences to study human behavior primarily in WEIRD populations. Here we argue that brain scientists are susceptible to similar biases, sampling primarily from WEIRD populations; and we discuss recent evidence from cultural neuroscience demonstrating the importance and viability of investigating culture across multiple levels of analysis.

Here, we argue that attackers in intergroup conflicts are also likely to hold strong identity fusion, anticipate threat from the out-groups, and retaliate by signaling preemptive aggressiveness, which may not be asymmetrically exclusive to defenders. We propose that the study of the intergroup and intragroup dynamics could highlight more specific, robust markers to differentiate types of defenders from attackers.

Cultural attachment (CA) refers to processes that allow culture and its symbols to provide psychological security when facing threat. Epistemologically, although we currently have an adequate predictivist model of CA, it is necessary to prepare for a mechanistic approach that will not only predict, but also explain CA phenomena. Towards that direction, we first examine the concepts and mechanisms that are the building blocks of both prototypical maternal attachment and CA. Based on existing robust neuroscience models we associate these concepts (...) and mechanisms with bona fide neurobiological functions to advance an integrative neurobiological model of CA. We end by discussing the unresolved relationship of CA to other similar socio-cognitive concepts. The aim of the paper is to highlight the importance of integrating CA theory into computational approaches to culture and evolution (such as predictive processing computations explaining niche construction) as this will allow a dynamic interpretation of cultural processes.
