The study, published Wednesday in Springer’s _Journal of Gambling Studies_, says that all humans fall victim to illusory patterns — if a roulette ball lands on black five turns in a row, for example, it is normal to think that it must surely land on red next. But compulsive gamblers see more such imaginary patterns and are different to recreational gamblers by their increased likelihood to bet on the false trends. “Our results suggest that gamblers are more willing to bet impulsively on perceived illusory patterns,” stated co-lead author Wolgang Gaissmaier in a press release. In a laboratory, the team compared the betting habits of 91 habitual gamblers versus 70 people who were not. Participants were shown pictures of two slot machines and had to predict the winner, but the catch was one had a 67% chance of producing a win while the other machine produced a win only 33% of the time. Participants were not explicitly told of the probability difference but the study said it “could be learned from experience via feedback.” The results showed that gamblers were more likely than non-gamblers to use ‘probability matching’ — or making predictions based on past results. “They are overly prone to accept random series of events as, in fact, non-random — and non-random enough to be worth betting on,” said Gaissmaier. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/3841369/gamblers-gambling-addiction-gaming-patterns/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/3841369/gamblers-gambling-addiction-gaming-patterns/"},"headline":"Habitual Gamblers See Patterns Where There Are None, Study Says","datePublished":"2015-04-30T09:10:17.000Z","dateModified":"2026-02-22T06:48:33.454Z","description":"\"Gamblers are more willing to bet impulsively on perceived illusory patterns,\" researcher says","url":"https://time.com/3841369/gamblers-gambling-addiction-gaming-patterns/","keywords":["Addiction","Mental Health","study","Research","health","gambling","Las Vegas","casinos","Mental Health/Psychology"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/bltd7a0cd77a780b9e9/6987edab2dce01cb9f9e1950/gambling-addiction-las-vegas.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Kevin McSpadden","jobTitle":null,"url":"https://time.com/author/kevin-mcspadden/"}],"articleSection":"Health","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/bltd7a0cd77a780b9e9/6987edab2dce01cb9f9e1950/gambling-addiction-las-vegas.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"Las Vegas Sands deceived a Nevada court in an attempt to stall a lawsuit by the former head of its Macau operations, a state judge ruled on Friday, fining the casino operator and abridging its right to object in a fight over key evidence.
