    Why has the pandemic increased support for Universal Basic Income?

    Get PDF
    COVID-19 has led to a marked increase in positive discussion of Universal Basic Income in political and media circles. Yet we do not know whether there has been a corresponding increase in support for the policy in the public at large, and if so why. Daniel Nettle presents two studies on this question carried out in April and May 2020. The results illustrate how the pandemic has brought about shifts in policy preferences, through changes in citizens’ perceptions of what is important

    Hanging on to the Edges: Essays on Science, Society and the Academic Life

    What does it mean to be a scientist working today; specifically, a scientist whose subject matter is human life? Scientists often overstate their claim to certainty, sorting the world into categorical distinctions that obstruct rather than clarify its complexities. In this book Daniel Nettle urges the reader to unpick such distinctions—biological versus social sciences, mind versus body, and nature versus nurture—and look instead for the for puzzles and anomalies, the points of connection and overlap. These essays, converted from often humorous, sometimes autobiographical blog posts, form an extended meditation on the possibilities and frustrations of the life scientific. Pragmatically arguing from the intersection between social and biological sciences, Nettle reappraises the virtues of policy initiatives such as Universal Basic Income and income redistribution, highlighting the traps researchers and politicians are liable to encounter. This provocative, intelligent and self-critical volume is a testament to the possibilities of interdisciplinary study—whose virtues Nettle stridently defends—drawing from and having implications for a wide cross-section of academic inquiry. This will appeal to anybody curious about the implications of social and biological sciences for increasingly topical political concerns. It comes particularly recommended to Sciences and Social Sciences students and to scholars seeking to extend the scope of their field in collaboration with other disciplines

    The behavioural constellation of deprivation: Causes and consequences

    Get PDF
    Socioeconomic differences in behaviour are pervasive and well documented, but their causes are not yet well understood. Here, we make the case that a cluster of behaviours is associated with lower socioeconomic status (SES), which we call “the behavioural constellation of deprivation.” We propose that the relatively limited control associated with lower SES curtails the extent to which people can expect to realise deferred rewards, leading to more present-oriented behaviour in a range of domains. We illustrate this idea using the specific factor of extrinsic mortality risk, an important factor in evolutionary theoretical models. We emphasise the idea that the present-oriented behaviours of the constellation are a contextually appropriate response to structural and ecological factors rather than a pathology or a failure of willpower. We highlight some principles from evolutionary theoretical models that can deepen our understanding of how socioeconomic inequalities can become amplified and embedded. These principles are that (1) small initial disparities can lead to larger eventual inequalities, (2) feedback loops can embed early-life circumstances, (3) constraints can breed further constraints, and (4) feedback loops can operate over generations. We discuss some of the mechanisms by which SES may influence behaviour. We then review how the contextually appropriate response perspective that we have outlined fits with other findings about control and temporal discounting. Finally, we discuss the implications of this interpretation for research and policy

    Bottom of the heap: having heavier competitors accelerates early-life telomere loss in the European starling, sturnus vulgaris

    Early-life adversity is associated with poorer health and survival in adulthood in humans and other animals. One pathway by which early-life environmental stressors could affect the adult phenotype is via effects on telomere dynamics. Several studies have shown that early-life adversity is associated with relatively short telomeres, but these are often cross-sectional and usually correlational in design. Here, we present a novel experimental system for studying the relationship between early-life adversity and telomere dynamics using a wild bird, the European starling (Sturnus vulgaris). We used cross-fostering to experimentally assign sibling chicks to either small or large broods for twelve days of the growth period. We measured telomere length in red blood cells using quantitative PCR near the beginning of the experimental manipulation (4 days old), at the end of the experimental manipulation (15 days old), and once the birds were independent (55 days old). Being in a larger brood slowed growth and retarded wing development and the timing of fledging. We found no evidence that overall brood size affected telomere dynamics. However, the greater the number of competitors above the focal bird in the within-brood size hierarchy, the greater was the telomere loss during the period of the experimental manipulation. The number of competitors below the focal in the hierarchy had no effect. The effect of heavier competitors was still evident when we controlled for the weight of the focal bird at the end of the manipulation, suggesting it was not due to retarded growth per se. Moreover, the impact of early competition on telomeres was still evident at independence, suggesting persistence beyond early life. Our study provides experimental support for the hypothesis that social stress, in this case induced by the presence of a greater number of dominant competitors, accelerates the rate of telomere loss

    A marker of biological ageing predicts adult risk preference in European starlings, Sturnus vulgaris

    Why are some individuals more prone to gamble than others? Animals often show preferences between 2 foraging options with the same mean reward but different degrees of variability in the reward, and such risk preferences vary between individuals. Previous attempts to explain variation in risk preference have focused on energy budgets, but with limited empirical support. Here, we consider whether biological ageing, which affects mortality and residual reproductive value, predicts risk preference. We studied a cohort of European starlings (Sturnus vulgaris) in which we had previously measured developmental erythrocyte telomere attrition, an established integrative biomarker of biological ageing. We measured the adult birds’ preferences when choosing between a fixed amount of food and a variable amount with an equal mean. After controlling for change in body weight during the experiment (a proxy for energy budget), we found that birds that had undergone greater developmental telomere attrition were more risk averse as adults than were those whose telomeres had shortened less as nestlings. Developmental telomere attrition was a better predictor of adult risk preference than either juvenile telomere length or early-life food supply and begging effort. Our longitudinal study thus demonstrates that biological ageing, as measured via developmental telomere attrition, is an important source of lasting differences in adult risk preferences

    Status and mating success amongst visual artists

    Geoffrey Miller has hypothesized that producing artwork functions as a mating display. Here we investigate the relationship between mating success and artistic success in a sample of 236 visual artists. Initially, we derived a measure of artistic success that covered a broad range of artistic behaviors and beliefs. As predicted by Miller’s evolutionary theory, more successful male artists had more sexual partners than less successful artists but this did not hold for female artists. Also, male artists with greater artistic success had a mating strategy based on longer term relationships. Overall the results provide partial support for the sexual selection hypothesis for the function of visual ar

    The relationships between exercise and affective states: a naturalistic, longitudinal study of recreational runners

    Background Although people generally feel more positive and more energetic in the aftermath of exercise than before, longitudinal research on how exercise relates to within-person fluctuations in affect over the course of everyday life is still relatively limited. One constraint on doing such research is the need to provide participants with accelerometers to objectively record their exercise, and pagers to capture affective reports. Aims We aimed to develop a methodology for studying affect and exercise using only technology that participants already possess, namely GPS running watches and smartphones. Using this methodology, we aimed to characterize within-individual fluctuations in affective valence and arousal in relation to bouts of exercise, and explore possible moderators of these fluctuations. Methods We recruited a sample of 38 recreational runners. Participants provided daily affective reports for six weeks using their smartphones. Information on their runs was harvested from their own GPS devices via an online platform for athletes. Results Average valence and arousal were higher on days when the person had run than on the next day, and higher the day after a run than on the days after that. Over the course of the day of a run, valence and arousal declined significantly as the time since the run increased. Physically fitter participants had more positive valence overall, and this was particularly true when they had not run recently. There was some evidence of higher-dose (i.e., longer and faster) runs being associated with lower arousal on the next and subsequent days. Gender did not moderate associations between running and valence or arousal. Discussion Our study demonstrated the potential for studying the associations between affect and exercise in a way that is precise, undemanding for participants, and convenient for researchers, using technologies that participants already own and use

    Why are there social gradients in preventative health behavior? A perspective from behavioral ecology.

    Get PDF
    Abstract Background: Within affluent populations, there are marked socioeconomic gradients in health behavior, with people of lower socioeconomic position smoking more, exercising less, having poorer diets, complying less well with therapy, using medical services less, ignoring health and safety advice more, and being less health-conscious overall, than their more affluent peers. Whilst the proximate mechanisms underlying these behavioral differences have been investigated, the ultimate causes have not

    Mitigating social and economic sources of trauma:the need for Universal Basic Income during the Coronavirus Pandemic

    Get PDF
    The COVID-19 Pandemic is projected to cause an economic shock larger than the Global Financial Crisis of 2007/2008 and a recession as great as anything seen since the Great Depression in 1930s. The social and economic consequences of lockdowns and social distancing measures, such as unemployment, broken relationships and homelessness create potential for inter-generational trauma extending decades into the future. In this article, we argue that, in the absence of a vaccine, governments need to introduce Universal Basic Income as a means of mitigating this trauma
