This chapter discusses the different subgroups of Sanhe gods – day laborers, job intermediaries, and gambling dogs – and their experiences of becoming precarious to varying degrees. It also explores the space of the urban village that sustains the everyday life of Sanhe gods, providing them with food, shelter, clothing, showering, pawning, and other types of goods and services. It ends with a discussion on the subculture of Sanhe gods and its presence on the internet.
Placebo and nocebo effects are widely reported across psychiatric conditions, yet have seldom been examined in the context of gambling disorder. Through meta-analysis, we examined placebo effects, their moderating factors, and nocebo effects, from available randomised, controlled pharmacological clinical trials in gambling disorder.
Methods:
We searched, up to 19 February 2024, a broad range of databases, for double-blind randomised controlled trials (RCTs) of medications for gambling disorder. Outcomes were gambling symptom severity and quality of life (for efficacy), and drop outs due to medication side effects in the placebo arms.
Results:
We included 16 RCTs (n = 833) in the meta-analysis. The overall effect size for gambling severity reduction in the placebo arms was 1.18 (95%CI 0.91–1.46) and for quality of life improvement was 0.63 (0.42-0.83). Medication class, study sponsorship, trial duration, baseline severity of gambling and publication year significantly moderated effect sizes for at least some of these outcome measures. Author conflict of interest, placebo run-in, gender split, severity scale choice, age of participants or unbalanced randomisation did not moderate effect sizes. Nocebo effects leading to drop out from the trial were observed in 6% of participants in trials involving antipsychotics, while this was less for other medication types.
Conclusion:
Placebo effects in trials of pharmacological treatment of gambling disorder are large, and there are several moderators of this effect. Nocebo effects were measureable and may be influenced by medication class being studied. Practical implications of these new findings for the field are discussed, along with recommendations for future clinical trials.
High rates of psychiatric comorbidities have been found in people with problem gambling (PBG), including substance use, anxiety, and mood disorders. Psychotic disorders have received less attention, although this comorbidity is expected to have a significant impact on the course, consequences, and treatment of PBG. This review aimed to estimate the prevalence of psychotic disorders in PBG.
Methods
Medline (Ovid), EMBASE, PsycINFO (Ovid), CINAHL, CENTRAL, Web of Science, and ProQuest were searched on November 1, 2023, without language restrictions. Studies involving people with PBG and reporting the prevalence of schizophrenia spectrum and other psychotic disorders were included. Risk of bias was assessed using the Joanna Briggs Institute critical appraisal checklist for systematic reviews of prevalence data. The pooled prevalence of psychotic disorders was calculated using a random effects generalized linear mixed model and presented with forest plots.
Results
Of 1,271 records screened, 22 studies (n = 19,131) were included. The overall prevalence of psychotic disorders was 4.9% (95% CI, 3.6–6.5%, I2 = 88%). A lower prevalence was found in surveyed/recruited populations, compared with treatment-seeking individuals and register-based studies. No differences were found for factors such as treatment setting (inpatient/outpatient), diagnoses of psychotic disorders (schizophrenia only/other psychotic disorders), and assessment time frame (current/lifetime). The majority of included studies had a moderate risk of bias.
Conclusions
These findings highlight the relevance of screening problem gamblers for schizophrenia spectrum and other psychotic disorders, as well as any other comorbid mental health conditions, given the significant impact such comorbidities can have on the recovery process.
Gambling disorder affects 0.5–2.4% of the population and shows strong associations with lifetime alcohol use disorder. Very little is known regarding whether lifetime alcohol use disorder can impact the clinical presentation or outcome trajectory of gambling disorder.
Methods
Data were pooled from previous clinical trials conducted on people with gambling disorder, none of whom had current alcohol use disorder. Demographic and clinical variables were compared between those who did versus did not have lifetime alcohol use disorder.
Results
Of the 621 participants in the clinical trials, 103 (16.6%) had a lifetime history of alcohol use disorder. History of alcohol use disorder was significantly associated with male gender (relative risk [RR] = 1.42), greater body weight (Cohen’s D = 0.27), family history of alcohol use disorder in first-degree relative(s) (RR = 1.46), occurrence of previous hospitalization due to psychiatric illness (RR = 2.68), and higher gambling-related legal problems (RR = 1.50). History of alcohol use disorder was not significantly associated with other variables that were examined, such as severity of gambling disorder or extent of functional disability. Lifetime alcohol use disorder was not significantly associated with the extent of clinical improvement in gambling disorder symptoms during the subsequent clinical trials.
Conclusions
These data highlight that lifetime alcohol use disorder is an important clinical variable to be considered when assessing gambling disorder because it is associated with several untoward features (especially gambling-related legal problems and prior psychiatric hospitalization). The study design enabled these associations to be disambiguated from current or recent alcohol use disorder.
Decision-making deficits, assessed cognitively, are often associated with mental health symptoms, however, this relationship is not fully understood. This paper explores the relationship between mental health disorders and decision-making, using the Cambridge Gambling Task (CGT). Our study investigated how decision-making varied across 20 different mental health conditions compared to controls in a sample of 572 young adults from the Minneapolis and Chicago metropolitan areas, using a computerized laboratory-based task. Almost all mental health conditions were associated with at least mild (i.e. at least small effect size) impairment in all three studied parameters of the CGT (risk adjustment, quality of decision-making and overall proportion of bet). Notably, binge eating disorder had the largest cognitive impairment and gambling disorder had moderate impairment. Post-traumatic stress disorder (PTSD) was associated with impaired decision-making while obsessive–compulsive disorder (OCD) and depression showed moderate impairment. Additionally, half of the disorders assessed had moderate to large impairment in risk adjustment.These findings suggest that mental health conditions may have a more complex cognitive profile than previously thought, and a better understanding of these impairments may aid in risk assessment and targeted clinical interventions. This study underscores the need for further research to determine the causal pathways between mental health conditions and cognition, as well as to better understand the day-to-day impact of such deficits.
Abundant moments of indecision and delay shape George Eliot’s last novel Daniel Deronda (1876), which treats uncertainty as a recursive movement between interior and exterior, potentiality and activity. This chapter shows how Eliot explores action’s convoluted antecedents, drawing on intellectual trends in mid-century comparative method and physiological psychology, especially the latter’s portrait of embodied willing and pathologies of volition. These contexts frame a reading of the novel’s twin stances of practical experience and intellectual reflection: hesitation, the bewildering experience of having a “will which is and yet is not yet,” and its rational cousin, comparison, “our precious guide.” Formal fluctuations and portrayals of mental caprice would seem at cross-purposes with Eliot’s narrative control and moral coherence. Yet in discovering a “kinship” between certainty and doubt, she reinvigorates her novelistic ethics and recasts sympathy as guaranteed by “closer comparison between the knowledge which we call rational & the experience which we call emotional.” Her characters set store by irresolute stances of hesitation and comparison, and predictive affects like trust and hope.
As literary realism shed earlier providential paradigms, William Thackeray inaugurated a startling interest in alternatives to reality as essential for novels that would be true to life. These “queer speculations” saturate his writing: a child who might have lived, an accident that could have been avoided, a war that would have ended otherwise if only …. Thackeray’s counterfactual imagination matures from occasional stories of the 1840s, through Vanity Fair (1847–48), the Roundabout Papers (1860–63), and Lovel the Widower (1860). His conditionals range from frenzied anticipation to paralyzing regret, developing from wild wagers and total reversals of fortune in the early sketches to a late style where memory, narrative, and writing itself are marked by virtuality. This chapter examines uncertain experience in Thackeray’s oeuvre in relation to historical writing of the eighteenth and nineteenth centuries and accounts of counterfactual reasoning in psychology and narrative theory. Probing uncertainty’s emotional and tonal modulations, Thackeray’s writing widens the space of novelistic realism to include the nonmimetic, hypothetical, improbable, and open-ended – or what he terms the “might-have-beens.”
This chapter studies two contrasting models for predictive thinking and representation in Thomas Hardy. In The Return of the Native (1878), Hardy’s depiction of repetitive phenomena evokes one renovated account of logico-mathematical probability, John Venn’s empirical theory about how we judge from series of instances. In the novel’s palpably antiquated rural setting – where characters intuit more than they see, gamble by the light of glowworms, and infer human plots from long-run traces in the material world – the abstractions of Victorian logic acquire concrete form. In The Mayor of Casterbridge (1886), by contrast, serial iterations are compressed into images. Hardy designs literary equivalents of Francis Galton’s “composite photographs,” used to model statistical data and mental processes. Characters think in overlays, detecting a parent’s face playing over that of a child, designing a future self by laying transparencies over the present, and imagining human plots as grids from overhead. Serial and composite thinking extend to Hardy’s “approximative” theory of fiction. He uses these tropes as an implicit riposte to critics and advocates for a novelistic realism tolerant of repetition, coincidence, and improbability.
The Romans had to cope with uncertainty and, in part, did so through a shared set of knowledge and practices, which this chapter calls a risk culture. These ways of coping contained a lower level of individuality, consciousness or reflexivity than Beck’s modern Risk Society. There was also no simple divide between lay and expert knowledge. The Roman world exposed its inhabitants to a variety of risks but the accumulated experience of coping with these represented a mutual way of mitigating the dangers.
This article discusses the rise of modern banking, the invention of credit and a related persistent orientation to the future inherent in credit-based economies, through the example of the novel which, as a literary form, came into being at roughly the same time. As a distinctly commercial genre and as a product of the financial revolution, novels ask readers to ‘credit’ the stories they tell with truthfulness, and to invest them with a particular form of credibility as significant narratives. At the same time, novels invite readers to imagine ‘as if’ scenarios and possible worlds in much the same way that borrowed capital enables people to construct life worlds based on resources not yet realised through investment in a speculative economy. Therefore, by examining how finance and gambling debts circulate in one particular text from the eighteenth century - Francis Burney's Cecilia - as a primary example of how credit and fictionalisation grew up together, this article argues that credit and risk feed into the narrative accounting and recounting of the text and articulate the affective structure of the financialised future that we have now inherited, and which informs how we understand ourselves as subjects, as well as how we interact with finance as a form of entertainment.
Social media are changing the way people are exposed to products with addictive potential – including gambling. This chapter provides a brief overview of the way digital technologies like social media are changing the gambling landscape and their relationship with gambling harm. Traditional approaches to gambling harm reduction have largely failed to recognize and address many of the systemic factors that shape the environment in which gambling harm occurs, such as promotion of gambling. Greater regulatory attention is needed to prevent social media from contributing to harm, especially among vulnerable groups such as minors and people experiencing gambling problems.
Gambling disorder is common, affects 0.5–2% of the population, and is under-treated. Duration of untreated illness (DUI) has emerged as a clinically important concept in the context of other mental disorders, but DUI in gambling disorder, has received little research scrutiny.
Methods
Data were aggregated from previous clinical trials in gambling disorder with people who had never previously received any treatment. DUI was quantified, and clinical characteristics were compared as a function of DUI status.
Results
A total of 298 individuals were included, and the mean DUI (standard deviation) was 8.9 (8.4) years, and the median DUI was 6 years. Longer DUI was significantly associated with male gender, older age, earlier age when the person first started to gamble, and family history of alcohol use disorder. Longer DUI was not significantly associated with racial-ethnic status, gambling symptom severity, current depressive or anxiety severity, comorbidities, or disability/functioning. The two groups did not differ in their propensity to drop out of the clinical trials, nor in overall symptom improvement associated with participation in those trials.
Conclusions
These data suggest that gambling disorder has a relatively long DUI and highlight the need to raise awareness and foster early intervention for affected and at-risk individuals. Because earlier age at first gambling in any form was strongly linked to longer DUI, this highlights the need for more rigorous legislation and education to reduce exposure of younger people to gambling.
The introduction sets out the intent of the book, an overview of the major works in the field, and a view of the arguments appearing in each chapter. Gambling is central to the cultural, social, and intellectual history of the nineteenth century. Studying casino gambling provides a way to see how nineteenth-century Europeans understood their changing world, even as it also reflected those changes itself. In this way gambling was used in an explanatory capacity, one that let contemporaries probe the inner workings of the machine and the creation of knowledge. If we want to understand the intricate dance of society, culture, politics, and ideas, then gambling is a useful tool to pry open these different stories, allowing us to see better large historical transformations.
Online gambling emerged in the 1990s in the midst of a process of market liberalisation. Here, scholars have argued that the gambling industry actively seeks state regulation to authorise and legitimate its activities. Why then, since the emergence of the online gambling industry, have trade associations continually sought to develop responsible gambling codes of conduct? In this paper, I address this puzzle by documenting and tracing the development and deployment of responsible gambling codes of conduct by trade associations from the emergence of the online gambling industry in the early 1990s and through processes of increased market liberalisation at the national level and market integration at the European Union level. I argue that online gambling trade associations deploy responsible gambling codes of conduct at particular moments of opportunity to shape their members’ external legal and regulatory environment and to reproduce and embed a particular understanding of how gambling-related risks should be regulated.
Gambling was central to the cultural, social, and intellectual history of nineteenth-century Europe. By tracing the evolution of gambling and investigating the spatial qualities of the casino, this book reveals how Europeans used gambling to understand their changing world. The development of resorts and the architectural qualities of casinos demonstrate how new leisure practices, combined with revolutions in transportation and communication, fashioned resort gambling in the Rhineland and Riviera. Jared Poley explores the importance of casino gambling in people's lives, probing how gambling and fate intersected. The casino impacted understandings of the body, excited emotions, and drove the 'psychology' of the gambler, as well as affecting ideas about probability, chance, and luck. Ultimately, this book addresses the fundamental question of what gambling was for, and how it opened up opportunities to understand theories about aggression, play, and human development.
In late 1823- early 1824 London society was agog at news of a brutal murder that took place just north of the metropolis in Hertfordshire. A professional gambler, William Weare, was killed by John Thurtell and his accomplices Joseph Hunt and William Probert, all denizens of the ‘flash’ underworld that was the subject of Pierce Egan’s outstandingly successful book and play, Life in London (1821). The minor theatres of the Surrey and the Royal Coburg, the latter only recently opened in 1818, sought to capitalise on the sensational case by putting on melodramas in the weeks following news of the murder breaking in the London press in late October 1823. These plays were subject to censorship, unusually not by the authorities, but by legal intervention on the behalf of the accused John Thurtell on the grounds that the virtual re-enactment of the murder (including the appearance of the actual carriage or gig used to transport Weare to his death) would prejudice his trial in February 1824. The fate of these dramas thus represents a new perspective on the history of the censorship of the theatre, as well as offering insights into the intersections of theatre, scandalous celebrity, the metropolitan ‘flash’, print publicity, and the genre of melodrama in the formative decade of the 1820s.
Researchers have found evidence of both hot hand and gambler’s fallacy biases in lottery number selection. Which of the two opposite effects is observed is often dependent upon the nature of the lottery game, the particular sample, the local culture of the participants, or the time transpired since the seed event. By observing hundreds of millions of lottery entries over 118 consecutive semiweekly drawings, we present evidence of both effects and their longitudinal properties. With respect to the selection of individual numbers, lottery participants tend to avoid recently selected winning numbers. This gambler’s fallacy effect diminishes and the number becomes increasingly ‘hot’ until it is selected again. With respect to winning number combinations, we found strong evidence of a small but persistent hot hand bias. This bias gradually diminishes over time, but remains detectable and highly consistent for a number of years.
This paper uses proprietary data from a blackjack table in Las Vegas to analyze how the expectation of regret affects peoples’ decisions during gambles. Even among a group of people who choose to participate in a risk-taking activity, we find strong evidence of an economically significant omission bias: 80% of the mistakes at the table are caused by playing too conservatively, resulting in substantial monetary losses. This behavior is equally prevalent among large-stakes gamblers and does not change in the face of more complicated strategic decisions.
Frederick, Levis, Malliaris & Meyer (2018) report a package of laboratory studies where participants underestimate the value of “hedges”: Risky bets which cancel out the risk of another presently-held bet. However, it might be questioned to what extent laboratory findings predict field behavior. People might better understand hedges when more money is at stake, or when they have more time to reflect. We discuss three gamblers who, instead of hedging, used a costly “cash-out” option to eliminate the risk of their bets on Leicester FC’s improbable victory in the 2015/2016 English Premier League soccer season. The decision to cash-out rather than to hedge led to individual losses of up to £8,000, and did not seem plausibly explained by rational economic factors. High-stakes hedges are misunderstood too.
