In this spectacularly brilliant episode – brought to you by GLI! – we explore the complexities of problem gambling, risk prediction models, and regulatory challenges. Join us as Dr. Rob Heirine shares insights from his research on using behavioural data to identify at-risk gamblers and evaluate harm reduction policies.What we talk about, but in a list: Challenges in predicting problem gambling using operator dataLimitations and biases in self-reported problem gambling measures like PGSIThe importance of target variables and transparency in predictive modelsPractical considerations for implementing affordability checks and loss limitsThe role of behavioural indicators and real-time detection in interventionEthical and regulatory issues around thresholds, metrics, and model explainabilityChoice quotes: "Changing the target is more vital than tweaking algorithms.""The subjective misunderstanding of one's spending is a potent risk signal.""A system's credibility hinges on how well stakeholders understand and trust its judgments.""Current risk is best assessed over recent days or weeks.""Simplicity introduces bias, leading to over- or under-inclusion of at-risk individuals.""Trust in algorithms depends on rigorous validation and openness.""Gambling harm is not solely a behavioural phenomenon but includes personal, social, and mental health dimensions."Timestamps:00:00 - Introduction and guest Dr. Rob Heirine's background01:30 - Challenges of predicting problem gambling from operational data03:00 - Limitations of self-exclusion as a predictor04:45 - The difficulty of behavioural and self-reported measures06:00 - The importance of target variables and validation in modeling08:00 - How model transparency influences regulation and trust10:30 - Effectiveness of prompts and limit-setting policies13:00 - Problems with using short-term data windows for prediction15:30 - The small prevalence of problem gamblers and implications for models17:00 - Using treatment-seeking behavior as a risk indicator19:00 - Thresholds and rule-based approaches vs. complex models21:30 - Challenges of real-time behavioural detection and lag in intervention23:00 - The importance of transparency, explainability, and trust in algorithms25:00 - Behavioural discrepancies, underestimating spending, and subjective experiences28:00 - Incorporating affordability and expenditure data into predictive models31:00 - Evaluation metrics: sensitivity, specificity, and their limitations in gambling research34:00 - Using behavioral indicators like deposit and withdrawal patterns37:00 - Feedback systems and behavioral summaries as harm prevention tools40:00 - Combining behavioral and self-report data for effective risk assessment43:00 - The effect of participant bias in surveys and population estimates46:00 - Measuring harm at population vs. individual risk levels48:00 - Optimal time windows for assessing gambling behaviourResources & Links:GLI: https://gaminglabs.com/Rob on LinkedIn: https://www.linkedin.com/in/robert-heirene/The Gambling Files on LinkedIn: https://www.linkedin.com/company/the-gambling-files-podcast/Addiction: An Hour With Auer is a weekly podcast where hosts Dr Michael Auer – he of the title – and Jon Bruford talk about addiction in all its forms.
