Washington [US], August 3 (ANI): New large-scale research shows that winning does not cause people to cheat, in stark contrast to a previous high-profile study.

A 2016 paper by Israeli researchers reported a series of experiments, which claimed that winners of skill-based competitions are more likely to steal money in subsequent games of chance against different opponents, as opposed to losers or people who did not see themselves as winners or losers.

This highly-cited study of relatively small sample sizes proposed that competitive winning induces a sense of entitlement that encourages cheating.

But now, an expanded and enhanced study by researchers at the University of Leicester (UK) and the University of Southern California (USA), published today (Wednesday) in the journal Royal Society Open Science, has refuted the original findings.

The international team of researchers found that people with a strong sense of fairness cheat less -- regardless of whether they had previously won or lost.

They examined the behaviour of 259 participants in a lab-based dice-rolling game -- identical to the original study -- and 275 participants undertaking a basic coin-tossing game in an additional online experiment. The results were then analysed using standard statistics plus a mathematical technique called structural equation modelling.

Researchers found that a small but significant amount of cheating occurred for the financial rewards on offer, just as in the original study. However, winning did not increase subsequent cheating or increase people's sense of entitlement -- and neither did losing.

Instead, the only factor investigated which could account for the small (but significant) amount of the cheating that occurred was low 'inequality aversion'.

People with inequality aversion dislike unequal outcomes. Those with a strong sense of fairness tend to be inequality averse, and they avoid cheating because they view the practice as a form of unfairness.

Andrew Colman is a Professor of Psychology within the University of Leicester's Department of Neuroscience, Psychology and Behaviour, and also served as lead author for the new study.

Professor Colman said: "Cheating and general dishonesty are of growing concern in the light of academic dishonesty in the digital age, problems of tax avoidance and evasion by wealthy people in developed economies, and more generally effects of widening inequality in wealth and income on corruption and crime.

"We were surprised by the findings in the 2016 study, and that's why we wanted to replicate it with substantial sample sizes. The original study's small samples do not have the statistical power to generate firm conclusions.

"We were amazed when it turned out that neither winning nor losing had any effect on cheating although a significant amount of cheating occurred. We have at least provided scientifically sound data that give a clear answer to the question." (ANI)
