Stir up a glass of muddy water and try to clear it by hand. Swirl it, pick at it, will it clean — and it just gets muddier. Set it down and walk away, and in twenty minutes it’s clear on its own. Laozi used that image in the Tao Te Ching around 400 BCE to describe patience as a skill, not a mood. And a 2025 study published in the International Journal of Research in Marketing — newly covered by phys.org this month — just found the mechanism underneath it.

The short version: mindfulness makes people more willing to wait for a bigger reward later. Not because meditation makes the reward look more appealing. Because it makes the wait feel shorter.

The Quick Version

Six studies by Amy Errmann, a marketing researcher at Auckland University of Technology, found that mindfulness meditation increases people’s willingness to wait for delayed rewards — by slowing subjective time perception, not by changing how much they value the reward. In a mindful-walking experiment, willingness to wait for a larger reward jumped from 36% to 69% after a short session. Laozi described the same shift 2,400 years earlier: clarity comes to those who can wait quietly while the mud settles, not to those who force the water clear.

The Quick Verdict

Question	What the research found
Does mindfulness make people more patient?	Yes — measurably, across six studies, two of them with real money and real coupons on the line.
Does it work by making the reward seem better?	No. Reward size sensitivity was unchanged.
So what changes?	Time perception. The future feels closer and less costly to wait for.
Does the effect hold for long waits?	Yes, out to six months, in the study that tested it.
Did anyone predict this mechanism before neuroscience did?	Laozi, more or less, in the Tao Te Ching’s chapter on muddy water.

The Six Studies, Briefly

Amy Errmann’s research, published in the International Journal of Research in Marketing in 2025, ran mindfulness against ordinary intertemporal choice — the classic “money now vs. more money later” decision that behavioral economists have been studying for decades. Two of the six studies happened in the field, with actual consequences. Four were lab experiments, three of those using choices people actually had to live with rather than hypotheticals on a survey.

The numbers are the part worth sitting with.

In a mindful-walking experiment, participants chose between a $5 gift card right now and a $10 gift card one week later. Before the walk, only 36% chose to wait. After a short mindfulness session, 69% did. Same choice, same people, same reward — the only thing that moved was a few minutes of paying attention to their breath and their steps.

The bakery study is the one I keep coming back to, because it wasn’t a lab with grad students. Real customers, in a real bakery, choosing between a smaller coupon now and a bigger one in two weeks. Watch a short mindfulness video first, and 78% waited for the bigger coupon. Watch an ordinary food video instead — same length, same setting — and only 51% did.

That’s not a rounding-error effect. That’s the difference between most people choosing patience and most people choosing the smaller, immediate reward, flipped by a few minutes of attention training.

Time, Not Value — And That’s the Interesting Part

Here’s where the study earns its place next to a 2,400-year-old philosophy text instead of just another productivity headline.

Errmann’s team also tested what happens when you make the future reward much bigger — does mindfulness just make people greedier for the larger payout, more willing to hold out for anything sizeable? No. The effect held when researchers stretched the waiting period from three months out to six, with mindful participants staying just as willing to wait while the control group’s patience eroded. But it didn’t respond to reward size at all. As Errmann put it plainly: mindfulness “changed people’s sensitivity to time, but not to the size of the reward.”

That’s a specific, falsifiable claim, and it’s the one that matters. If mindfulness worked by making people value future rewards more — a kind of enhanced rational calculation — you’d expect bigger future rewards to produce even bigger patience gains. They didn’t. What moved was how expansive the future felt. Mindful participants reported feeling like they had more time ahead of them, which made the wait itself feel less like a cost.

Put differently: mindfulness doesn’t make the destination look better. It makes the road shorter.

What Laozi Actually Said About This

Chapter 15 of the Tao Te Ching asks a version of the same question the marketing researchers eventually tested: “Who can wait quietly while the mud settles? Who can remain still until the moment of action?” It’s not a rhetorical flourish. It’s a description of a specific, trainable capacity — the ability to stop stirring, stop forcing, and let a process complete itself on its own timeline.

People misread this passage as passivity, the same way they misread wu wei — Laozi’s broader concept of effortless action — as doing nothing. It isn’t. Waiting quietly is active. It’s a discipline against your own impulse to intervene, poke, check the glass again, stir it “just a little” to see if it’s cleared yet. The mud doesn’t settle faster because you want it to. It settles at its own rate, and the only variable you control is whether you disturb it further.

That’s structurally identical to what Errmann’s data shows about time perception. The muddy-water metaphor isn’t about the reward being worth the wait — Laozi never argues that clear water is more valuable than muddy water in some escalating way. He argues that the wait itself is the thing most people can’t tolerate, and that tolerating it is a skill separate from wanting the outcome. Which is exactly the split the marketing data found: reward value untouched, time tolerance transformed.

Laozi didn’t have a lab. He had two and a half thousand years of watching people fail to leave things alone. That turned out to be enough.

Why the Mechanism Matters More Than the Advice

“Be more patient” is advice everyone’s heard and mostly ignored, because it doesn’t say what to actually do. This is the same trap Rilke was pushing against when he told a young poet to live the questions instead of hunting for premature answers — the advice to “just wait” fails until you know what waiting is actually made of. Knowing how mindfulness produces patience is more useful than the platitude version, for one specific reason: it tells you where the leverage is.

If patience were about willpower, the fix would be gritting your teeth harder. If it were about better valuing the future — teaching yourself that the bigger reward really is worth it — the fix would be a spreadsheet, a vision board, some calculation exercise. Neither is what the data supports.

The lever is subjective time. Mindfulness — paying attention to breath, body, and the present moment without judging it — appears to expand how spacious the near future feels, which lowers the felt cost of waiting for it. That’s a mechanism you can actually practice, distinct from trying to want the reward more or trying to muscle through the wait on discipline alone.

A Practice Worth Trying

You don’t need a mindful-walking class or a bakery with a video screen to test this. Try it before a decision that involves waiting — a purchase, a reply you’re tempted to send too fast, a project you want to rush to finish:

1. Pause for two or three minutes before you decide. Not to think about the decision — to notice your breath, the sounds in the room, the feeling of sitting or standing. This is the part people skip because it feels unrelated to the choice. It isn’t.
2. Notice, don’t force. If your attention drifts to the decision itself, don’t fight it — just come back to the breath. The point isn’t to blank your mind. It’s to let a few minutes pass without stirring the water.
3. Then decide. Ask what the wait actually costs you, now that you’re not rushing to escape it. Often the honest answer is: less than it felt like ninety seconds ago.

This isn’t a trick to make yourself want less. It’s a way of interrupting the felt urgency that makes “later” seem unbearably far away when it usually isn’t.

Where This Doesn’t Help

Mindfulness didn’t make people value bigger rewards more — which means it’s not a tool for talking yourself into a bad deal because you’ve meditated your way into more patience about it. If the wait is genuinely not worth it — the “reward” later is smaller than it looks, or the delay serves someone else’s interest more than yours — no amount of stillness should change that math. The Stoic dichotomy of control is the useful check here: patience is for things worth waiting on. It’s not a general-purpose argument for tolerating anything indefinitely.

And it’s worth saying plainly: this research is about ordinary decision fatigue and impulsive choice, not clinical impulse-control conditions. If waiting genuinely feels impossible in a way that’s affecting your finances, relationships, or health, that’s a conversation for a professional, not a breathing exercise.

The Muddy Water Doesn’t Need Your Help

The unsettling part of Errmann’s research, if you sit with it, is how little effort the actual mechanism requires. Nobody in the mindful-walking study was taught to value the $10 gift card more. Nobody in the bakery was persuaded the bigger coupon was a better deal. They already knew that — everyone always knows the bigger, later reward is objectively better, and people choose the smaller one right now anyway, constantly, knowingly. That’s the entire problem intertemporal choice research exists to study.

What changed wasn’t the math. It was the felt distance to a future that, a few minutes earlier, seemed too far away to be worth reaching for.

Laozi’s line isn’t really about water. Who can wait quietly while the mud settles — that’s a question about whether you can stop interfering with a process that was already working, given time. Twenty-four centuries later, a researcher in Auckland ran the experiment and got the same answer he did: the ones who wait quietly are the ones who get the clear water. Not because they wanted it more. Because they stopped stirring.
