COVID-19 has not affected all scientists equally. A survey of PI's finds that female scientists, those in the ‘bench sciences’ and especially scientists with young children experienced a substantial decline in time devoted to research
Does oxytocin increase trust?
A registered replication of an influential 2005
@Nature
study by some of the original authors found no evidence of oxytocin on trust in the same conditions
Although people tend to stick to their beliefs (rather than following the evidence), Melnikoff (
@DEMelnikoff
) and Strohminger show that this irrational tendency may still result from fully rational Bayesian calculations.
How can the social & behavioural sciences support the COVID-19 pandemic response? 43 experts share insights and highlight research gaps in this Perspective published today:
Much of our charitable giving is ineffective. Why are we motivated to give, but not to give effectively?
The findings of 5 experiments by Burum et al suggest we are more sensitive to effectiveness of our donations when helping ourselves or our families.
How do markets relate to morality?
@BenjaminEnke
analyses historical folklore to find that a society's degree of market interactions is associated with the cultural salience of prosocial behaviour, interpersonal trust, and universalist moral values.
Leveraging literary history, Baumard et al. find that higher levels of economic development are associated with a greater incidence of love in narrative fiction.
How universal are moral judgments? Including participants from 45 countries,
@BenceBago
et al. find that the situational factors that affect moral reasoning are shared across countries – with little observed cultural variation.

Groups coordinate more effectively when individuals are able to learn from others' successes. Here,
@hawkrobe
et al. use sensing experiments to test how individual social inference abilities shape the emergent behaviour of human groups.
Lackner et al. show that individuals with an intermediate level of science knowledge tend to have overconfidence in their own knowledge, and negative attitudes to science.

Data from more than 4,500 9- to 10-year-olds show no evidence that bilingual children have an advantage in executive functions, the cognitive abilities that are central to the voluntary control of thoughts and behaviours.

A meta analysis of 205 effect sizes shows that corrections of science-relevant misinformation were, on average, not successful. But they work better for issues that are not politically polarizing:
Analysing over 48K government interventions in 200+ countries in Mar-Apr 2020, Haug et al. find that combinations of softer measures, e.g. risk communication or increasing healthcare capacity, can be almost as effective against COVID-19 as lockdowns.
Retraction Note for "Machine learning of neural representations of suicide and emotion concepts identifies suicidal youth". The method used overestimated classification accuracy because the features of the classifier were tuned to that particular dataset.

"Fresh" scientific teams - teams with members who have never collaborated before - produce papers with greater originality and greater multidisciplinary impact New paper from An Zeng, Ying Fan, Zengru Di, Yougui Wang & Shlomo Havlin
Attention and working memory both fluctuate over time. deBettencourt et al. demonstrate that fluctuations in attention and memory in distinct tasks are synchronous, providing additional evidence for the tight integration of these cognitive processes.
Social media data are incredibly useful for research on human behaviour. But researchers must use platform-owned APIs to access them, which are not compatible with Open Science principles, explain

Intracranial brain stimulation in humans elicits a large variety of perceptual, motor, and cognitive effects. Fox et al. show strong links between the distribution and content of these responses and the brain’s intrinsic network architecture.
Governments should measure pain as a key aspect of societal well-being, alongside metrics like happiness. A comment by Lucía Macchia highlights the importance of measuring pain as a crucial component of national well-being programs.

How do people decide whether to seek information? Sharot and Sunstein propose a framework of information seeking that relies on estimates of the potential impact of information on action, affect, and cognition.
Risk aversion may be caused by the way we perceive larger monetary rewards, rather than just economic theories of value. Those with more precise mental representations of magnitude show less risk-averse behavior.

Why do groups of individuals sometimes exhibit collective ‘wisdom’ and other times maladaptive ‘herding’? A new NHB study shows that apparent conflict is regulated by the social learning strategies deployed
