    An agent-based model of SARS-CoV-2 transmission shows that testing, contact tracing and household quarantine could keep new COVID-19 waves under control while allowing the reopening of the economy with minimal social-distancing interventions.

    Black early-career researchers suffer racism, discrimination and significant barriers to professional development. Mya Roberson makes key suggestions on how non-Black scientists can support Black early-career researchers.

    Electrical stimulation of the human cortex, undertaken for brain surgery, triggers percepts and feelings. A new study documents an ordering principle to these effects: the farther removed from sensory input or motor output structures, the less likely it is that a region contributes to consciousness.

    In cases of direct replications or direct critiques of earlier work, feedback from the original authors can have an important role to play in the evaluation process, but such feedback is by definition not impartial. Our signed comments policy allows such feedback to be incorporated in the consideration process, without impacting the objectivity of peer review and editorial evaluation.

    COVID-19 has not affected all scientists equally. A survey of principal investigators indicates that female scientists, those in the ‘bench sciences’ and, especially, scientists with young children experienced a substantial decline in time devoted to research. This could have important short- and longer-term effects on their careers, which institution leaders and funders need to address carefully.

    Bias and racism in the biomedical community thwart scientific advancement, reduce the pipeline of diverse clinicians and scientists, and contribute to racial and ethnic health disparities. We advocate for proactive antiracism approaches to eliminate barriers impacting people of colour, promote equity and achieve a more effective biomedical community.

    Do purchasable randomised reward mechanisms in video games (loot boxes) constitute gambling? Opinions often rest on whether virtual items obtained from loot boxes have real-world value. Using market data from real transactions, we show that virtual items have real-world monetary value and therefore could be regulated under existing gambling legislation.

About the Journal

  • Nature Human Behaviour publishes research of outstanding significance into any aspect of human behaviour: its psychological, biological, and social bases, as well as its origins, development, and disorders. The journal aims to enhance the visibility of research into human behaviour, strengthening its societal reach and impact.

  • We publish a range of content types including original research articles, Reviews, Perspectives, Comments, World Views, News & Views, Correspondences, and Research Highlights that elaborate on significant advances in the field and cover topical issues.

  • Nature Human Behaviour is staffed by a dedicated team of professional editors, with relevant research backgrounds. It is led by Stavroula Kousta, formerly the Editor of Trends in Cognitive Sciences and Senior Editor at PLOS Biology, and also includes Aisha Bradshaw, Jamie Horder, Charlotte Payne, and Anne-Marike Schiffer.

  • In addition to our in-house editors, Nature Human Behaviour has an external advisory panel to assist journal development in science and policy.

  • Witchcraft beliefs are and have been widespread in human societies, but what impact do they have on social interactions and what cultural evolutionary function might they serve? Field experiments and network data show that the witchcraft label ‘Zhu’ influences labour-sharing and reproductive choices in a large network of southwest Chinese villages. Zhu is not an indicator of prosociality, but may function to spite or damage rivals [1]. 1. Mace, R., Thomas, M.G., Wu, J., He, Q., Ji, T. & Tao, Yi. Nat. Hum. Behav. https://www.nature.com/articles/s41562-017-0271-6 (2018)

  • An illustration of neurofeedback training guided by an animated scenario [1]. Real-time modulations in the amygdala electrical fingerprint signal are reflected by audiovisual changes in the unrest level of a virtual 3D scenario (a typical hospital waiting room), manifested as the ratio between characters sitting down and those loudly protesting at the counter. The video shows an example both for down- and up-regulation training; in the current study [1], only down-regulation training was conducted. The participant consented to appear in the video. 1.

  • Cultural products have a life of their own: academic papers get cited and songs get downloaded. While scholars have studied these patterns, we know little about how to model the decay of attention. In this study Candia and colleagues model the attention received by cultural products, including scientific papers, patents, songs, movies, and biographies, and show that all these decay following a universal bi-exponential function, which may be due to the differing functions of communicative and cultural collective memory [1].

COVID-19 and human behaviour

Human behaviour has been critical in shaping the COVID-19 pandemic, and the actions of individuals, groups, nation states and international bodies all have a role to play in curbing its spread. This means that insights from behavioural, social and health sciences are and will continue to be invaluable throughout the course of the pandemic. In this Focus, we bring together original research and expert viewpoints from a broad spectrum of disciplines that provide insight into the causes, impacts, and mitigation of the pandemic, highlighting how research on individual and collective behaviour can contribute to an effective response.
