  • In this Perspective, Fjell and Walhovd argue that, to account for considerable interindividual variability in sleep need, future research must consider environmental, individual and situational factors when studying the impact of sleep on cognitive and brain health.

    • Anders M. Fjell
    • Kristine B. Walhovd
    Perspective
  • In this Perspective, the authors examine the psychological factors that shape attitudes towards AI tools, while also investigating strategies to overcome resistance when AI systems offer clear benefits.

    • Julian De Freitas
    • Stuti Agarwal
    • Nick Haslam
    Perspective
  • Artificial intelligence tools and systems are increasingly influencing human culture. Brinkmann et al. argue that these ‘intelligent machines’ are transforming the fundamental processes of cultural evolution: variation, transmission and selection.

    • Levin Brinkmann
    • Fabian Baumann
    • Iyad Rahwan
    Perspective
  • Behavioural science is increasingly used in the public and private sectors, but it has been subject to several criticisms. This Perspective proposes a manifesto for behavioural science, addressing these criticisms and describing a way forward for the field.

    • Michael Hallsworth
    Perspective
  • The coming years are likely to see slowing economic growth, which has significant consequences for developed democracies. This Perspective by Burgess et al. considers the implications of slowed growth and proposes a guided civic revival approach to addressing challenges.

    • Matthew G. Burgess
    • Amanda R. Carrico
    • Steve Vanderheiden
    Perspective
  • Wagenmakers and colleagues describe seven statistical procedures that increase transparency in data analysis. These procedures highlight common ground among data analysts from different schools and find inspiration in Merton’s ethos of science.

    • Eric-Jan Wagenmakers
    • Alexandra Sarafoglou
    • Balazs Aczel
    Perspective
  • Although intellectual humility is a prerequisite for credible science, it is rarely practised. Hoekstra and Vazire make recommendations on how to increase intellectual humility in research articles and highlight the crucial role of peer reviewers in promoting intellectually humble manuscripts.

    • Rink Hoekstra
    • Simine Vazire
    Perspective
  • Behavioural science increasingly informs policy, but findings are not always replicated. Bryan et al. describe an emerging heterogeneity revolution. They recommend that researchers use heterogeneity in treatment effects to develop more robust theories of causality and strengthen the field.

    • Christopher J. Bryan
    • Elizabeth Tipton
    • David S. Yeager
    Perspective
  • Risk-pooling systems have been developed as a way to collectively manage risk and can protect against loss in times of crisis. Cronk and Aktipis present seven design principles for risk-pooling systems and discuss how they are used by human communities worldwide.

    • Lee Cronk
    • Athena Aktipis
    Perspective
  • Nielsen et al. argue for more involvement of behavioural scientists in addressing the challenge of globally increasing biodiversity loss, identifying important gaps in existing knowledge and outlining core components for a robust evidence base.

    • Kristian Steensen Nielsen
    • Theresa M. Marteau
    • Andrew Balmford
    Perspective
  • How can we determine the best way of measuring a psychological construct? Bach et al. propose a ‘retrodictive validity’ approach, in which candidate methods are ranked based on their sensitivity to detect known effects, with the most sensitive then being favoured for use in novel scenarios.

    • Dominik R. Bach
    • Filip Melinščak
    • Manuel C. Voelkle
    Perspective
  • Dubois and colleagues describe how a testable framework for personality research, delineating personality’s causal and constitutive relations with genes, environment, brain, mind and behaviour will benefit the field.

    • Julien Dubois
    • Frederick Eberhardt
    • Ralph Adolphs
    Perspective
  • Giurge and Whillans et al. highlight the problem of time poverty, explore the factors that drive it, discuss its personal and social consequences, and call for more research attention to this pervasive form of poverty.

    • Laura M. Giurge
    • Ashley V. Whillans
    • Colin West
    Perspective
  • Lorenz-Spreen et al. argue that effective web governance is needed to empower individuals online. They describe two classes of behavioural interventions—nudging and boosting— that can help redesign online environments for informed and autonomous choice

    • Philipp Lorenz-Spreen
    • Stephan Lewandowsky
    • Ralph Hertwig
    Perspective
  • Leroi et al. argue that neutral models, which are evolutionary models that do not involve a process of natural selection, must be applied with care, and that alternative methods are often needed to conclusively explain the diversity of variants.
