What it argues
The Procrastination Equation is Piers Steel's attempt to apply a decade of academic research on procrastination to a popular audience. Steel, a professor of organizational behavior, argues that procrastination is not a time management problem or a character flaw but a failure of motivation rooted in how humans discount future rewards. His central formula — called the temporal motivation theory — expresses this mathematically: motivation to do a task is a function of the expectation of success multiplied by the value of completing it, divided by impulsiveness multiplied by the delay until completion. When a task feels uncertain, unpleasant, or far off, motivation collapses.
The value of the formula is that it makes explicit what most self-help advice treats as a black box. Why does a deadline help? Because it reduces the denominator. Why do rewards help? They increase the numerator. Why does a task feeling too hard hurt? It lowers the expectation of success. Steel's framework translates every piece of procrastination advice into a specific mechanical intervention: you're not just "being more disciplined," you're adjusting a particular variable in a motivation equation.
What it gets right
- 1.
Procrastination is a motivation failure, not a time management failure. The temporal motivation theory explains it as what happens when low expectation, low value, high impulsiveness, and long delay combine.
- 2.
Impulsiveness — sensitivity to immediate rewards relative to future ones — is the single strongest predictor of procrastination. It is partly biological and substantially trainable.
- 3.
Task aversion drives procrastination as much as delay. When a task is unpleasant, boring, or anxiety-inducing, the brain's time preference for immediate relief overrides rational planning.
What it covers
Who wrote it
Piers Steel is a professor of organizational behavior at the Haskayne School of Business at the University of Calgary. He has spent more than a decade researching procrastination and is considered one of the leading academic authorities on the subject. His meta-analysis of procrastination research, published in the journal Psychological Bulletin in 2007, is one of the most cited papers in the field. The Procrastination Equation translates his research into accessible form for a general audience.
