Imagine sitting in a completely blank room with a single, perfectly squishy, powdery-sweet marshmallow right in front of you. A scientist says you can eat it right now, OR if you wait fifteen whole minutes all by yourself... you get TWO marshmallows! Could you do it? In this mind-bending episode, Mira and Finn explore the famous Marshmallow Test, a psychology experiment run by Walter Mischel in the 1960s. Discover the hilarious lengths kids went to in order to resist the yummy treat, from covering their eyes to singing loud songs, and even petting the marshmallow like a tiny dog! You'll learn the secret to "delayed gratification" and how playing tricks on your own brain can boost your self-control. But wait, there is a giant plot twist! For years, people thought this candy test predicted who would be successful in life. Join the hosts as they dig into real science to uncover why those old claims were mostly wrong, and how a kid's family background actually played the biggest role in their choice. Get ready to test your brain and learn the ultimate waiting tricks!

Welcome to Philosophy is not boring by kidopoly.com. I'm Mira! And I'm Finn. Okay, Finn, I want you to use your imagination for a second. Picture a single, perfectly squishy, powdery sweet marshmallow sitting on a plate right in front of you.

SPEAKER_01

Ooh, I can totally picture it. I would eat it immediately.

SPEAKER_00

Hold on, here is the catch. A scientist tells you that you can eat it right now. Or if you sit in that room all by yourself for 15 whole minutes without touching it, you get two marshmallows.

SPEAKER_01

Ugh 15 minutes? If you're just sitting there staring at it, that is basically a hundred years.

SPEAKER_00

Do you think you could do it? Today we're exploring one of the most famous psychology experiments ever run, the marshmallow test.

SPEAKER_01

So it is literally just a test to see who really loves marshmallows the most.

SPEAKER_00

Actually, it's way deeper than that. On this show we talk about philosophy, but we also talk about psychology, which is asking big questions about how our minds actually work. So we are asking big questions about our own brains. Exactly. And for decades, people thought this marshmallow test could predict your entire future, from your school grades to your whole life. But today we're going to see why real science means checking your facts. Because the truth turned out to be completely different. So, back in the late 1960s, a psychologist named Walter Michel set up this experiment at Stanford University.

SPEAKER_01

Wait, he was a famous scientist, and his big idea was giving candy to kids.

SPEAKER_00

Essentially, yes. He ran this test with four and five-year-olds at a place called Bing Nursery School.

SPEAKER_01

Oh, so kids a couple years younger than me? Still, pretty little.

SPEAKER_00

Right. But Michel wasn't just interested in candy. He was studying a big concept called delayed gratification.

SPEAKER_01

Delayed gratifi-what? That sounds like a spell from a wizard movie.

SPEAKER_00

It really does. Gratification is just a fancy word for getting something that feels good or rewarding. So delayed gratification means giving up a small reward right now, so you can get a much bigger reward later.

SPEAKER_01

Oh wait! Like when I saved up my allowance for a whole month to buy that huge remote control car, instead of just buying a tiny candy bar at the grocery store that day.

SPEAKER_00

Exactly. You delayed your gratification. And Walter Michel wanted to know: how do human beings actually do that? Because resisting something right in front of you is really, really hard.

SPEAKER_01

Especially if I was four. If a marshmallow was right there, just staring at me. I don't know if my brain could handle it.

SPEAKER_00

To make it even harder, he set up a special room that was completely blank. No toys, no books, no pictures on the walls, just a desk, a chair, and a plate with a treat.

SPEAKER_01

That sounds like torture. A blank room with nothing to do but stare at a marshmallow. Exactly.

SPEAKER_00

The researchers left the kids totally alone in that blank room and watched them through a hidden window to see what would happen.

SPEAKER_01

What did the kids do? Did they just grab it?

SPEAKER_00

Some kids popped it in their mouths the absolute second the door closed, but others really, really tried to hold out for the full 15 minutes. How?

SPEAKER_01

If you just stare at it, wouldn't you go crazy?

SPEAKER_00

Yes. Staring at it is exactly what you shouldn't do. The kids who successfully waited did hilarious things to distract themselves. Like what kind of things? They covered their eyes with their hands, they turned their chairs completely around to face the blank wall, so they couldn't even see the table.

SPEAKER_01

Oh, out of sight, out of mind. That is actually really smart.

SPEAKER_00

Some sang loud songs to themselves, kicked the desk, and one kid even gently petted the marshmallow like it was a tiny, squishy little animal.

SPEAKER_01

A pet marshmallow. He was probably pretending it was a fluffy dog, so he wouldn't want to eat it.

SPEAKER_00

You totally nailed it. Let's do a quick thought experiment. Tell me what makes a marshmallow tempting.

SPEAKER_01

It's super squishy and white, and it tastes like sugary vanilla.

SPEAKER_00

Right. Michelle called those hot thoughts. If you think about how sweet and chewy it is, the temptation is hot and you will eat it. But if you pretend it's a pet or a little white cloud, you cool the thought down.

SPEAKER_01

Whoa, so willpower isn't just gritting your teeth, it is a trick you play on your own brain. Exactly.

SPEAKER_00

But here is where the story gets a little messy, and why we always have to question the things we are told.

SPEAKER_01

Uh-oh. What happened with the pet marshmallows?

SPEAKER_00

Well, years later, Walter Michelle and other scientists checked in on those exact same kids when they were teenagers and adults.

SPEAKER_01

And what did they find out?

SPEAKER_00

For a long time, the famous story was that the kids who waited for two marshmallows did far better in life. They got higher test scores, and people claimed they were just more successful.

SPEAKER_01

Wait, so if a kid ate the marshmallow right away, everyone thought they were doomed? That doesn't seem fair at all.

SPEAKER_00

It isn't fair, and luckily, it also isn't entirely true. People loved the idea because it felt like a nice moral story. If you're good and patient, you succeed. But true psychology requires real evidence. So what did the real evidence say? In 2018, a scientist named Tyler Watts and his team did the experiment again. But this time they tested hundreds of kids from all sorts of different neighbourhoods and backgrounds. Oh, so they checked the facts on a bigger scale. Exactly! And they found that the ability to wait was actually tied heavily to a kid's family background, especially how much money their family had. Wait, why would money change how you look at a marshmallow? Think about it. If you grow up in a house where there's plenty of food and promises are always kept, waiting 15 minutes is easy. You know that second marshmallow is definitely coming.

SPEAKER_01

Oh, but what if things are harder at home and sometimes the treats run out or promises get broken? Exactly.

SPEAKER_00

If life is unpredictable, eating the treat right away is actually a really smart, logical choice, because tomorrow's treat isn't guaranteed. It meant eating it right away wasn't about being weak at all.

SPEAKER_01

Wow, so all those people who judge the kids for eating the marshmallow early were totally missing the big picture.

SPEAKER_00

They really were. The new studies showed that the link between waiting and later success was actually quite small once you looked at the kids' true life circumstances.

SPEAKER_01

I like that so much better. It means a single marshmallow doesn't decide your destiny.

SPEAKER_00

Exactly! And that is why psychology is so cool. It's not about labelling people as good or bad, it's about figuring out how our environments shape us.

SPEAKER_01

So next time, I'm trying really hard not to eat the last chocolate chip cookie before dinner. I shouldn't just sit there staring at it and feeling bad.

SPEAKER_00

Right! Turn your chair around, go play a game, or sing a loud song. Self-control is just a skill you can practice. Distraction is your best friend when waiting is hard. I'm gonna go pet the cookie like a tiny dog. That might make your hands a little melty, but sure, go for it. And here's a mind-bending fun fact for you. This experiment became so famous around the world that even Sesame Street did an episode about it. Wait, really? Who took the test? Cookie Monster, of course. He wanted to join the Cookie Connoisseurs Club, so he had to learn those exact self-control tricks to wait without gobbling everything up.

SPEAKER_01

Whoa, if Cookie Monster can learn to cool down his hot thoughts and wait, I guess anyone can.

SPEAKER_00

Alright, Finn, time for the quiz. Are you ready?

SPEAKER_01

Okay, I'm ready.

SPEAKER_00

First question. Who's the psychologist that ran the first marshmallow test? Next one, where did this famous first experiment take place? Question three. How long did the kids have to wait to get the second treat? Here's number four. What was one funny trick the kids used to distract themselves? Last question. What did later scientists find was a huge reason some kids waited and others didn't? Great job! Let's see how you did. The first answer is Walter Michelle. For question two, it took place at Stanford University in the 1960s. The third answer is they had to wait 15 long minutes. For question four, they covered their eyes, sang songs, turned around, or even petted the marshmallow. And the final answer is their family background, like how much money or stability they had at home.

SPEAKER_01

You know, I really like that scientists went back and checked the marshmallow test again. It feels much fairer now that we know the whole story.

SPEAKER_00

Me too, Finn. It just shows that it's okay to ask hard questions and keep testing the things we think we know. Nobody has all the answers right away. Do I still get a marshmallow for doing the podcast though? Only if you wait. Hey everyone, if you learned a new trick for waiting today, please give us a five-star review.
