Wealthy individuals more prone to taking kids’ candy, Ig Nobel-winning research reveals

1. Economics: Wealth and Behaviour

Research by psychologists has indicated that individuals of higher socioeconomic status may exhibit a greater tendency toward selfish or unethical behaviour, including disregard for other road users, dishonesty in professional settings, and taking items intended for children. Dr Paul Piff, a social psychologist at the University of California, Irvine, commented: "I've followed the Ig Nobels since my early college days. I didn't think I'd ever win one."

Piff and his team observed that drivers of more expensive vehicles were more likely to ignore traffic laws and fail to yield to pedestrians. Additional findings suggested that wealthier participants were more inclined toward dishonesty in workplace scenarios. In one test, individuals were left unsupervised with a jar of sweets labelled as belonging to children. Upon the researchers' return, those identified as upper-class had taken nearly twice as many candies as those from lower-class backgrounds.

"The general pattern seems to be that with wealth and rising power, you become less engaged with the needs of others and less burdened by the needs of social relationships," Piff said. "Taking candy from children might be the least of our worries but it's emblematic of the tendency to prioritise one's own needs over those of others."

2. Biomechanics: Defining Kissing

Researchers at Oxford University secured recognition for the UK in the biomechanics category. Dr Matilda Brindle stated: "The whole team is thrilled." She and her team examined the evolutionary origins of kissing and required a precise scientific definition. They proposed: "non-agonistic interactions involving directed, infraspecific oral-oral contact with some movement of the lips/mouthparts and no food transfer."

Brindle, who is currently writing a book on non-reproductive sexual behaviour, has also researched the evolutionary basis of masturbation, positioning her as a possible repeat winner of the award. "We're so focused on penises, what they do and why they are important, but all these other sexual behaviours are important," she said.

4. Peace: Shared Adversaries

It is common to seek friends who are compassionate toward us, but those friends also engage with the wider world in ways that can influence our own circumstances. Dr Jaimie Krems at the University of California, Los Angeles, presented findings suggesting that individuals may appreciate friends who behave assertively toward their shared adversaries. "Sometimes we want our friends to be more vicious and indifferent when they interact with our enemies," she said. "I've felt, in many instances, incredibly loved when people have carried my hate for me and been willing to have my back."
