A new analysis published in Psychology & Marketing outlines how modern sports betting apps can propel users from casual wagering into harmful gambling, identifying a so-called sports betting harm spiral shaped by cognitive biases and digital platform features. The study is led by Weng Marc Lim of Sunway University and Wagner Junior Ladeira of the Escola Superior de Propaganda e Marketing, who sought to understand why casual fans slide into gambling distress.
Sports betting has shifted from occasional activity to a constant digital presence, with mobile platforms offering real‑time odds and quick in‑game wagers. The researchers argue this ubiquity effectively embeds betting in the daily rhythm of sport, increasing the risk of financial and emotional damage for frequent participants. They proposed an ordered sequence—the sports betting harm spiral—where cognitive biases significantly influence how bettors perceive and respond to losses.
To test the first half of the spiral, the team conducted an experiment with 101 participants using a simulated basketball betting platform. Participants were randomly assigned to either low or high betting intensity, with two micro-bets in the low‑intensity condition and eight in the high‑intensity one. The data showed that higher betting intensity amplified problem gambling severity by heightening competitive intensification, a mental state in which bettors feel a stronger drive to outperform others and prove their competence.
A second experiment with 77 participants used visual mockups of a mobile betting application, including a digital wallet representation to make financial stakes more tangible. Again, participants faced low or high engagement conditions. The researchers found that high-intensity betting fostered overconfidence bias, leading participants to overestimate their predictive skills and underestimate the role of random chance. This inflated confidence was linked to greater problem gambling severity.
To observe the mechanisms outside a strictly controlled setting, the researchers conducted a survey with 173 participants about their actual betting habits. They asked them to predict international soccer match outcomes based on real team statistics and measured overconfidence by comparing how certain participants felt about their predictions with their actual accuracy. The data partly supported the proposed harm spiral: higher self‑reported betting intensity correlated with stronger competitive urges, which in turn related to greater overconfidence and gambling severity. However, overconfidence did not predict gambling severity once competitive urges were accounted for, and the full sequence from competition through overconfidence to severity did not reach statistical significance. The authors note that because betting intensity was self‑reported rather than manipulated, causation cannot be established.
The researchers then explored recovery, recruiting 127 participants and randomising them to combinations of low or high betting intensity and scenarios of small or large financial losses. Severe losses generally increased intentions to seek help, particularly among highly engaged bettors, suggesting deep immersion makes users more sensitive to substantial losses once a threshold is crossed.
In a final study, 141 participants faced scenarios involving small or large losses over a simulated betting week and were prompted to attribute the loss outcomes internally or externally. When large losses were framed as due to external factors, intentions to seek help rose sharply; when losses were attributed to personal fault, the willingness to seek support did not increase in a statistically significant way. The researchers note that blaming oneself can trigger shame, which may suppress the urge to pursue outside help precisely when it is most needed.
The studies rely heavily on simulated platforms and self‑reported intentions rather than observed real‑money behaviour, and the authors caution that scenario-based experiments cannot fully capture the emotional and financial realities of actual losses. The university student samples used in several parts of the research may not reflect older bettors with different financial responsibilities.
The findings carry clear implications for both platform design and public policy. Features that frame betting as an interpersonal competition—such as public leaderboards and achievement badges—may unintentionally fuel gambling harm. The authors suggest developers could instead provide individualized feedback on betting patterns. They also propose interventions for public health messaging that reframe losses as the consequence of platform design rather than personal failure, potentially reducing shame and encouraging help‑seeking.
The study, Driven to Win, Destined to Lose? A Process Model of How Sports Betting Escalates Into Gambling Harm and Shapes Help‑Seeking, was authored by Wagner Junior Ladeira, Weng Marc Lim, Tareq Rasul, Fernando de Oliveira Santini, Musarrat Shaheen, and Farrah Zeba.
Researchers emphasise that the work offers guidance for platform developers and public policymakers seeking to curb gambling harm while acknowledging the limitations of the current evidence base.
