Here we show that WM tracts are differentially positioned in the cortical hierarchy to support specific cognitive functions, and that tracts spanning the hierarchy connect regions with greater cognitive diversity. Moreover, tracts situated within the same hierarchical level connect biologically similar regions, while those crossing the hierarchy bridge distinct biological milieux to support diverse cognitive functions. The placement of tracts in the cortical hierarchy also reflects developmental variation in tract microstructure and individual differences in cognition. Together, these findings provide a framework that moves beyond conventional categories of association or projection tracts and links WM tract anatomy to cortical organization, cognitive function, cortical neurobiology and neurodevelopment.

This large cross-national study examined public views on polygenic embryo testing. In a US sample (N = 1,467), participants were more willing to test for medical conditions (for example, heart disease) than non-medical traits (for example, antisocial behaviour or low intelligence), although over half supported testing for non-medical traits.

Here, to test this question, we used an annotated rest paradigm where participants rated and verbally described their thoughts after each rest period during functional MRI (N = 60). Our findings revealed rich and idiosyncratic thoughts across individuals. Similarity in thoughts was associated with more similar FC patterns within and across individuals. In addition, both thought ratings and topics could be decoded from FC. Furthermore, neuromarkers of these thoughts generalized to unseen individuals in the Human Connectome Project dataset (N = 908), where decoded thought patterns during rest predicted positive vs negative trait-level individual differences.

During the pandemic, behavioural and social sciences often studied human behaviour through the lens of alignment with public health recommendations, implicitly treating concern and compliance as desirable and rational. While understandable, this emphasis was relatively narrow. Uncertainty, uneven risk distribution and competing values could have led to heterogeneous appraisals of risk and intervention benefit, even with the evidence available at the time. We show that engaging with the possibility that people could have been heterogeneously rational can broaden understanding of behaviour during COVID-19. Our aim is not to revisit the legitimacy of the response but to encourage reflection on the role of behavioural and social sciences in knowledge generation and highlight opportunities to examine pandemic salience and risk calibration. We outline research directions to guide the field and strengthen decision-making, trust and adaptability in future crises, promoting short-term compliance and long-term trust. In this Perspective, the authors examine how behavioural and social sciences studied human behaviour during COVID-19.

These trends hold across different LLMs, prompts and contexts, with potential implications for diagnostic processes, personalization efforts, hiring assessments and cultural preservation.
