The Procrastination Equation

The Problem with Willpower

Every September, a parent calls me and says some version of the same thing: "My kid is smart, they just won't do the work." The implication is that there's a missing ingredient — motivation, discipline, grit — and if we could just inject it, everything would click.

But that framing is wrong. Willpower isn't a substance you have more or less of. It's an outcome. It's what happens when the conditions for action are met. And when they're not met, no amount of lecturing will manufacture it.

Steel's Formula

Piers Steel, a researcher at the University of Calgary, spent years studying procrastination across thousands of subjects. He synthesized the findings into a single equation:

Motivation = (Expectancy × Value) / (Impulsiveness × Delay)

This is the procrastination equation. The numerator is what pulls you toward action. The denominator is what pushes you away. Let's take each variable in turn.

Expectancy: "Can I Actually Do This?"

Expectancy is your belief that you can succeed at the task. Not in some abstract, self-esteem-poster way — but concretely. Do you know how to start? Can you picture what "done" looks like?

When expectancy is low, students don't procrastinate because they're lazy. They procrastinate because they're afraid. The task feels impossible, so they avoid it to protect themselves from the feeling of failure.

The fix isn't encouragement. It's decomposition. Break the task into something so small that failure feels unlikely. "Write your essay" becomes "write one sentence about a time you were surprised." That's a task with high expectancy.

Value: "Why Should I Care?"

Value is the second multiplier. A task can feel perfectly achievable and still get ignored if the student doesn't care about it.

This is where a lot of tutoring goes wrong. We try to make students care about things they authentically don't care about, and then we're surprised when it doesn't stick.

The better move is to connect the task to something they already value. A student who doesn't care about the SAT might care deeply about getting into a school where they can study marine biology. The SAT isn't the value — it's the bridge to the value.

Impulsiveness: "But My Phone Is Right There"

Impulsiveness is the first denominator variable, and it's the one that's gotten dramatically worse in the last decade. Students aren't more impulsive than they used to be. Their environment is more impulsive.

Every app on their phone is engineered by teams of brilliant people to capture and hold attention. Telling a sixteen-year-old to "just put your phone away" is like telling someone to ignore a fire alarm. The signal is designed to be irresistible.

The fix is environmental, not motivational. Study in a different room. Use website blockers. Leave the phone in another building. Change the default, and impulsiveness drops.

Delay: "It's Not Due Until Next Month"

The final variable is delay — the time between now and the deadline. The further away the deadline, the less urgency you feel. This is why students who "work well under pressure" aren't demonstrating a skill. They're demonstrating a broken relationship with delay.

The fix is artificial deadlines that feel real. A tutor checking in on Wednesday. A draft due to a writing partner by Friday. The deadline doesn't have to be the real deadline. It just has to be believed.

Putting It Together

The beauty of the equation is that it's diagnostic. When a student is stuck, you can ask: which variable is broken?

Usually it's not all four. Usually it's one, maybe two. Find the broken variable, intervene on that specific variable, and momentum often follows.

This is what I mean when I say tutoring is applied psychology. The content matters, obviously. But the real skill is reading the situation and knowing which lever to pull.
