Abstract When people are exposed to information that leads them to overestimate the actual amount of genetic difference between racial groups, it can augment their racial biases. However, there is apparently no research that explores if the reverse is possible. Does teaching adolescents scientifically accurate information about genetic variation within and between US census races reduce their racial biases? We randomized 8thand 9thgrade students (n = 166) into separate classrooms to learn for an entire week either about the topics of (a) human genetic variation or (b) climate variation. In a cross‐over randomized trial with clustering, we demonstrate that when students learn about genetic variation within and between racial groups it significantly changes their perceptions of human genetic variation, thereby causing a significant decrease in their scores on instruments assessing cognitive forms of prejudice. We then replicate these findings in two computer‐based randomized controlled trials, one with adults (n = 176) and another with biology students (n = 721, 9th–12thgraders). These results indicate that teaching about human variation in the domain of genetics has potentially powerful effects on social cognition during adolescence. In turn, we argue that learning about the social and quantitative complexities of human genetic variation research could prepare students to become informed participants in a society where human genetics is invoked as a rationale in sociopolitical debates.

Typological thinking in human genomics research contributes to the production and prominence of scientific racism
Public genomic datasets like the 1000 Genomes project (1KGP), Human Genome Diversity Project (HGDP), and the Adolescent Brain Cognitive Development (ABCD) study are valuable public resources that facilitate scientific advancements in biology and enhance the scientific and economic impact of federally funded research projects. Regrettably, these datasets have often been developed and studied in ways that propagate outdated racialized and typological thinking, leading to fallacious reasoning among some readers that social and health disparities among the so-called races are due in part to innate biological differences between them. We highlight how this framing has set the stage for the racist exploitation of these datasets in two ways: First, we discuss the use of public biomedical datasets in studies that claim support for innate genetic differences in intelligence and other social outcomes between the groups identified as races. We further highlight recent instances of this which involve unauthorized access, use, and dissemination of public datasets. Second, we discuss thememification,use of simple figures meant for quick dissemination among lay audiences, of population genetic data to argue for a biological basis for purported human racial groups. We close with recommendations for scientists, to preempt the exploitation and misuse of their data, and for funding agencies, to better enforce violations of data use agreements.

Advances in gene editing technologies for human, plant, and animal applications have led to calls from bench and social scientists, as well as a wide variety of societal stakeholders, for broad public engagement in the decision-making about these new technologies. Unfortunately, there is limited understanding among the groups calling for public engagement on CRISPR and other emerging technologies about 1) the goals of this engagement, 2) the modes of engagement and what we know from systematic social scientific evaluations about their effectiveness, and 3) how to connect the products of these engagement exercises to societal decision or policy making. Addressing all three areas, we systematize common goals, principles, and modalities of public engagement. We evaluate empirically the likely successes of various modalities. Finally, we outline three pathways forward that deserve close attention from the scientific community as we navigate the world of Life 2.0.more » « less

Abstract The Convention on Biological Diversity and the Nagoya Protocol on Access and Benefit-Sharing provide an international legal framework that aims to prevent misappropriation of the genetic resources of a country and ensure the fair and equitable sharing of benefits arising from their use. The legislation was negotiated at the behest of lower-income, biodiverse countries to ensure that benefits derived from research and development of genetic resources from within their jurisdictions were equitably returned and could thereby incentivize conservation and sustainable use of biodiversity. Despite good intentions, however, rapid adoption of access and benefit-sharing measures at the national level, often without participatory strategic planning, has hampered noncommercial, international collaborative genetic research with counterproductive consequences for biodiversity conservation and sustainable use. We outline how current implementation of the Convention of Biological Diversity and the Nagoya Protocol affect noncommercial research, such as that conducted in many disciplines in biology, including mammalogy. We use a case study from Brazil, an early adopter, to illustrate some current challenges and highlight downstream consequences for emerging pathogen research and public health. Most emerging pathogens colonize or jump to humans from nonhuman mammals, but noncommercial research in zoonotic diseases is complicated by potential commercial applications. Last, we identify proactive ways for the mammalogical community to engage with the Convention on Biological Diversity and the Nagoya Protocol, through sharing of nonmonetary benefits and working with local natural history collections. Leveraging international scientific societies to collectively communicate the needs of biodiversity science to policy makers will be critical to ensuring that appropriate accommodations are negotiated for noncommercial research.more » « less

An inclusive and socially legitimate governance structure is absent to address concerns over new agricultural biotechnologies. Establishing an agricultural bioethics commission devoted to inclusive deliberation on ethics and governance in agricultural and food biotechnology is urgent. Highlighting the social and ethical dimensions of current agricultural bioengineering disputes in the food system, we discuss how a nationally recognized policy forum could improve decision-making and increase public understanding of the issues. We clarify ways the concepts that are used to categorize food and frame governance of food affect consumer choices, and how dissemination of information and the mode of dissemination can contribute to social inequities. We cite the record of medically-oriented bioethic commissions and the history of international bioethic commissions in support of our argument, and end by discussing what such a commission dedicated to agriculture and food issues could reasonably be expected to achieve.more » « less

Cognitive neuroimaging researchers' ability to infer accurate statistical conclusions from neuroimaging depends greatly on the quality of the data analyzed. This need for quality control is never more evident than when conducting neuroimaging studies with children and adolescents. Developmental neuroimaging requires patience, flexibility, adaptability, extra time, and effort. It also provides us a unique, non-invasive way to understand the development of cognitive processes, individual differences, and the changing relations between brain and behavior over the lifespan. In this discussion, we focus on collecting magnetic resonance imaging (MRI) data, as it is one of the more complex protocols used with children and youth. Through our extensive experience collecting MRI datasets with children and families, as well as a review of current best practices, we will cover three main topics to help neuroimaging researchers collect high-quality datasets. First, we review key recruitment and retention techniques, and note the importance for consistency and inclusion across groups. Second, we discuss ways to reduce scan anxiety for families and ways to increase scan success by describing the pre-screening process, use of a scanner simulator, and the need to focus on participant and family comfort. Finally, we outline several important design considerations in developmental neuroimaging such as asking a developmentally appropriate question, minimizing data loss, and the applicability of public datasets. Altogether, we hope this article serves as a useful tool for those wishing to enter or learn more about developmental cognitive neuroscience.more » « less
