Context“Nudges” and other behavioral economic approaches exploit common cognitive biases (systematic errors in thought processes) in order to influence behavior and decision-making. Nudges that encourage the consumption of harmful products (for example, by exploiting gamblers’ cognitive biases) have been termed “dark nudges.” The term “sludge” has also been used to describe strategies that utilize cognitive biases to make behavior change harder. This study aimed to identify whether dark nudges and sludge are used by alcohol industry (AI)–funded corporate social responsibility (CSR) organizations, and, if so, to determine how they align with existing nudge conceptual frameworks. This information would aid their identification and mitigation by policymakers, researchers, and civil society.MethodsWe systematically searched websites and materials of AI CSR organizations (e.g., IARD, Drinkaware, Drinkwise, Éduc'alcool); examples were coded by independent raters and categorized for further analysis.FindingsDark nudges appear to be used in AI communications about “responsible drinking.” The approaches include social norming (telling consumers that “most people” are drinking) and priming drinkers by offering verbal and pictorial cues to drink, while simultaneously appearing to warn about alcohol harms. Sludge, such as the use of particular fonts, colors, and design layouts, appears to use cognitive biases to make health-related information about the harms of alcohol difficult to access, and enhances exposure to misinformation. Nudge-type mechanisms also underlie AI mixed messages, in particular alternative causation arguments, which propose nonalcohol causes of alcohol harms.ConclusionsAlcohol industry CSR bodies use dark nudges and sludge, which utilize consumers’ cognitive biases to promote mixed messages about alcohol harms and to undermine scientific evidence. Policymakers, practitioners, and the public need to be aware of how such techniques are used to nudge consumers toward industry misinformation. The revised typology presented in this article may help with the identification and further analysis of dark nudges and sludge.

Background: The provision of commercialised gambling products and services has changed radically in recent decades. Gambling is now provided in many places by multi-national corporations, with important implications for public health and policymaking. The United Kingdom is one of the most liberalised gambling markets globally, however there are few empirical analyses of gambling policy from a public health perspective. This study aims to provide a critical analysis of a core element of UK gambling policy, the provision of industry-funded youth gambling education programmes. Methods: Adopting a commercial determinants of health lens, a discourse theoretical analysis was conducted using the logics of critical explanation. The data comprised resources provided by three gambling industry-funded charities (GambleAware, GamCare and the Young Gamers and Gamblers Education Trust) and their partners. Results: The resources present a gambling education discourse that serves to reproduce the 'responsible gambling' agenda, while problematising children and young people. While the resources appear to offer educational content and opportunities for debate, the dominant focus is on teaching about personal responsibility and on the normalisation of gambling and gaming and their industries, while constraining the concept of agency. The resources encourage young people to act as individuals to control their impulses, and to correct what are portrayed as faulty cognitions with the aim of becoming responsible consumers. Our findings demonstrate how the gambling education discourse aligns with wider industry interests, serving to deflect from the harmful nature of the products and services they market while shifting responsibility for harm onto children, youth and their families. Conclusions: Despite being delivered in the name of public health, the resources construct a discourse favourable to corporate interests. Educators, parents, policymakers, and others need to be empowered to address the conflicts of interest that exist in the delivery of gambling industry-funded resources. The promotion of such industry-favoured interventions should not be allowed to undermine efforts to implement regulations to prevent gambling harms.
