The Satisfaction Treadmill

A YALE PSYCHOLOGIST CREATED THE MOST POPULAR COURSE IN YALE’S 300 YEAR HISTORY. OVER 3 MILLION PEOPLE ENROLLED IN THE FIRST YEAR. IT WAS ABOUT ONE THING. AND THE FINDING THAT MADE IT FAMOUS WAS SOMETHING HER STUDENTS CALLED THE MOST UNCOMFORTABLE TRUTH THEY HAD EVER HEARD.

Her name is Laurie Santos. Professor of psychology. Yale University.

In 2018 she created a course called The Science of Well-Being.

It became the most popular course in Yale’s 300 year history.

Not because it told people what they wanted to hear.

Because it told them what they had spent their whole lives getting wrong.

She started with one question.

If humans are so intelligent why are we so bad at knowing what will make us happy.

The research she compiled to answer that question produced findings that her students described as simultaneously obvious and completely devastating.

The first finding.

The things humans believe will make them happy have almost no lasting effect on wellbeing.

More money. A better job. The right relationship. The perfect body. The bigger house. The higher grade. The promotion.

Decades of research confirm that none of these produce lasting improvements in wellbeing. Not because they are bad things.

Because the brain was not designed to sustain happiness from external circumstances.

The mechanism is called hedonic adaptation.

The brain has a set point of happiness it returns to regardless of what happens.

Win the lottery. Within one year back to baseline.

Become paralysed. Within one year back to baseline. Get the promotion. Within weeks back to baseline.

The brain adapts to every new circumstance and returns to where it started. This is why nothing ever feels like enough for long enough.

Santos called this the satisfaction treadmill.

You work harder to get the thing you believe will make you happy.

You get it. You feel better briefly.

The brain adapts. You return to baseline.

Now you need the next thing.

The treadmill does not stop. It speeds up. And the happiness you were running toward stays exactly the same distance ahead.

The second finding.

The things that actually produce lasting improvements in wellbeing are things most people systematically deprioritise.

Strong social connection. Acts of kindness toward others. Savouring ordinary positive experiences. Adequate sleep. Physical movement. Gratitude practiced deliberately. Presence in the current moment.

Not because these feel more important. Because the brain was designed to respond to these specific inputs with sustained wellbeing.

The uncomfortable truth Santos’s students kept coming back to:

They already knew this.

Everyone knows that relationships matter more than money.

That experiences matter more than things.

That being present matters more than being productive. And everyone keeps choosing the things that do not work.

Because the brain is running a prediction system that is systematically miscalibrated.

Santos called it miswanting. The brain predicts that certain things will make it happy.

Those predictions are wrong.

Consistently. Measurably. Across cultures and generations.

And the brain keeps making the same wrong predictions because it was never updated with the evidence that they were wrong.

The brain predicts:

More money will make me significantly happier. Research shows the effect plateaus at a relatively modest income level.

Getting what I want will make me happy. Research shows wanting and having activate different neural systems. Getting often disappoints what wanting promised.

A change in circumstances will change how I feel. Research shows adaptation returns most people to baseline within months.

Santos’s course was essentially a software update.

Teaching people to want what actually works.

Not as philosophy. As a daily practice.

The specific behaviours that research confirms produce lasting wellbeing.

Not because they feel important.

Because they actually are.

The practice Santos found most immediately effective was the simplest.

Savouring.

The deliberate practice of fully experiencing positive moments as they happen.

Not photographing them. Not sharing them.

Not half-experiencing them while thinking about the next thing. Being fully present inside the good moment long enough for the brain to actually register it.

The research on savouring confirms what Hanson found with the 12 second practice.

The brain needs sustained attention on positive experience to encode it into long term memory.

Without deliberate savouring positive experiences happen and leave no lasting trace.

The brain has had the experience.

But it has not benefited from it.

The second practice Santos recommended: Concrete replanning.

Taking the time you currently spend pursuing things that do not work and deliberately redirecting it toward things that do.

Not as a sacrifice. As an investment. One hour less on the phone. One hour more with someone you love.

One purchase less. One experience more.

The research is unambiguous on which one produces more lasting wellbeing.

The third practice: Gratitude expressed specifically.

Not a gratitude list. Not a vague appreciation of life.

A specific person. A specific thing they did. A specific impact it had on you.

Written or spoken directly to them.

Santos’s research confirmed this single practice produces larger and more lasting improvements in wellbeing than almost any other intervention studied.

You are not broken for wanting the things that do not work.

Your brain was built to pursue status, resources and certainty because those things kept your ancestors alive.

They were right for the savanna.

They are miscalibrated for your life.

The update is available. It requires only doing what you already know works more consistently than you currently do.

Most people will spend their whole lives on the satisfaction treadmill chasing things they know will not satisfy them wondering why satisfaction never comes.

The rare ones will step off.

And invest in the things the research has confirmed actually work.

That investment is the most evidence-based decision available to a human being.
