You Think You Know The Marshmallow Test
Your ability to resist eating a marshmallow at age four was supposed to predict your entire future – or at least that’s what one of psychology’s most famous experiments claimed. Better SAT scores? Check. Higher salary? You bet. Even a lower BMI? Somehow, yes. For fifty years, this simple test has been used to lecture us about self-control and success. There’s just one tiny problem: the results didn’t hold up in multiple future studies. What’s interesting is that the real findings might explain a lot of what’s happening in modern society. From quiet quitting to YOLO investing, the REAL results of the Marshmallow Test might point us to the “why” that’s driving these behaviors.
The original 1972 study seemed straightforward: give a kid a marshmallow, tell them if they wait 15 minutes without eating it they’ll get two marshmallows, then watch what happens. The results suggested that children who could delay gratification were more likely to have better SAT scores and lower BMIs years later. But when researchers tried to replicate these findings, things got interesting. A 2018 study by Tyler Watts and colleagues, involving a sample size ten times larger than the original, found virtually no correlation between delayed gratification and later outcomes once they controlled for family background, home environment, and parental education.
Even more telling was a 2012 University of Rochester study that added a fascinating twist. Before the marshmallow test, researchers either proved themselves reliable (by delivering on a promised better art supply) or unreliable (by apologizing and saying they couldn’t deliver the better supplies). The children who experienced the reliable researcher waited an average of four times longer for the second marshmallow compared to those who dealt with the unreliable one. It wasn’t about willpower – it was about trust in the system.
This brings us to today, where younger generations are increasingly skeptical of traditional “delayed gratification” narratives. When your parents tell you to work hard for 40 years so you can retire comfortably, but you’ve watched housing prices triple while wages stagnate, that second marshmallow starts looking like a fantasy. When the probability of achieving traditional markers of success approaches zero in people’s minds, something fascinating happens: they become modern-day Epicureans. Instead of saving for a house they don’t believe they’ll ever afford, they spend on experiences. Instead of climbing the corporate ladder, they job-hop for immediate gains. The marshmallow isn’t just delayed – for many, it feels like it’s been removed from the room entirely.
And let’s be honest – today’s kids wouldn’t even want that second marshmallow. They’d probably ask if it was gluten-free, locally sourced, or available as a limited edition they could auction on an online platform. Maybe we need a new experiment: “If you don’t check your phone for a day, you’ll get double the Instagram likes.” Though let’s be real – the participants would probably act innocent while quietly asking their friends to sneak the results on how their posts were doing.
