Psychology says kids who only got dessert on Sundays and new shoes in September weren’t deprived — researchers found scarcity is what keeps enjoyment alive, and abundance quietly eats it

Some kids grew up getting certain things only once in a while.

Dessert on Sundays, never Tuesdays. New shoes in September, when school started, and not again until they’d been outgrown. One soda, at a restaurant, as a treat — never a fridge stocked with it at home.

To anyone looking in, it can seem a little sad. The other kids had dessert whenever, a closet that seemed to refill itself, soda on tap. Next to that, the once-a-week kid looks like they went without.

Something was happening in that house that the abundance kids missed. The scarcity wasn’t deprivation — it was building the one thing that’s hardest to give a kid on purpose — the ability to enjoy things. And there’s research on exactly how it works.

The word makes it sound like a punishment

A young girl sits at a table, gazing sadly at a slice of chocolate cake and a box with new black shoes—a moment colored by scarcity. A September calendar hangs on the wall in the softly lit, nostalgic kitchen.

Scarcity is a heavy word. It sounds like going without, like a cupboard that’s bare because there’s no money to fill it.

That isn’t what’s meant here. This kind has nothing to do with money. The dessert is right there in the cupboard, and the family could serve it any night — they just don’t. It’s possible all week; it only happens on Sundays. It’s a choice about how often, not about whether they can.

The difference matters, because those two do opposite things to a kid. A kid who never gets dessert at all learns it’s off the table and stops hoping for it. A kid who gets it every Sunday learns the opposite — that good things come, on a schedule, and are worth the wait. Same dessert, opposite lesson, and the whole difference is whether it ever shows up.

Put that way, saving dessert for Sundays isn’t the same as denying it. And how often the good stuff comes — the dessert, the new shoes, the day out — matters about as much as whether it comes at all.

Why the once-in-a-while thing keeps its shine

Three things keep Sunday dessert from ever going flat.

The first is the wait.

A kid who knows dessert comes on Sunday spends part of the week pointed at it — thinking about it, looking forward to it. That anticipation isn’t dead time before the dessert — it’s part of the pleasure, sometimes the biggest part. There’s a Saturday-night version of that kid already half-thinking about tomorrow’s scoop, the enjoyment starting a full day early. The everyday-dessert kid never gets that, because there’s nothing to look forward to when dessert shows up every night.

The second is contrast. Sunday dessert tastes sweet partly because Monday through Saturday didn’t have any — it stands out because the rest of the week is plain. Make every day dessert day, and there’s no plain week left for it to stand out against.

The third is attention. When dessert is rare, the kid pays attention to it — makes it last, stays inside the few minutes of it. When it’s on the table every night, there’s no reason to, so the noticing never gets practiced. The Sunday kid isn’t only eating better-tasting dessert; they’re getting years of practice at savoring, one Sunday at a time.

Underneath all three is the way the brain works — it’s built to adapt to whatever’s constant and stop noticing it, the way the hum of the fridge disappears, or the raise that felt enormous in March feels normal by June. Dessert every night would fade like that, background within a week. Sunday dessert never fades.

It’s not only dessert.

Anyone who grew up on Saturday-morning cartoons knows the feeling — six days of nothing, then one whole morning of them, a charge no all-day streaming queue has ever matched. Or the kid who got new shoes once a year, in September, and wore them like they were the best thing they owned, because they were — a whole year of wanting delivered in one pair. The kid whose closet refilled itself couldn’t have said which pair was new.

Getting things all the time makes it less special

Now flip it. The kid with the bottomless candy drawer, the closet that refills itself, the soda always cold in the fridge — they aren’t luckier, at least not where enjoyment is concerned. If anything, they have it harder.

When the candy’s always in the drawer, none of that happens. No wait, so no anticipation. No plain week, so no contrast. The brain files it under normal within days, and the candy stops being candy. It turns into furniture.

It’s easy to spot on a big enough Christmas morning — the kid with forty presents who’s listless by the tenth, tearing paper without looking at what’s underneath. That’s not ingratitude — it’s saturation. By the tenth present, there’s no attention left for the eleventh, so each new one adds less than the last, and some add nothing.

There’s a stranger cost, too, and it’s the one the research keeps circling. Having a lot doesn’t only flatten the candy in the drawer — it seems to dull the ability to savor everything else a little. In one study, people given a quick reminder of wealth enjoyed a piece of chocolate less and ate it faster than people who got no such reminder.

Just having plenty within reach turns the volume down on small pleasures.

This isn’t a case for depriving kids

A childhood of real, grinding scarcity — the anxious kind, where there’s no dessert because there’s no money — does its own damage, and it’s a different thing entirely. Kids who grew up like that often over-correct as adults, unable to let themselves have the dessert (or the shoes, or the expensive dinner) even when they can afford a bakery’s worth.

The point is smaller.

When a few things are held back so they stay special — dessert on Sundays, shoes in September — the kid keeps the three parts that make enjoyment work — the wait, the contrast, and the attention that turns a scoop of ice cream into an event. And none of it costs the kid the dessert. They still get it — the scoop, the toy, the trip — they just also get the wanting, the waiting, and the shine that survives only when it isn’t there every single night.

The parents who rationed it to Sundays probably couldn’t have named the psychology behind it, but they knew what people used to know — dessert every night stops being a treat. Their kids grew up knowing how to want something, wait for it, and love it when it came, which is hard to teach on purpose, and they pulled it off by accident.
