The Science of Procrastination: Why It's About Feelings, Not Laziness

3 the researchers behind it — 'I'm such a lazy person' is one of the most common ways people explain their procrastination to themselves — and one of the most inaccurate ones. Deca

University of Calgary

Piers Steel

Known for:The definitive meta-analysis of procrastination research and the temporal motivation theory of why we delay

Key findings

  1. 2006

    Temporal motivation theory integrates expectancy, value, impulsiveness and delay into one account of motivation over time: a task's pull weakens the further away its payoff sits — which is why distant deadlines barely move us until they loom. ↗

  2. 2007

    Across 691 correlations, the strong and consistent predictors of procrastination were task aversiveness, task delay, self-efficacy and impulsiveness — and estimates indicate 80-95% of college students procrastinate, almost 50% consistently and problematically. ↗

Carleton University

Timothy A. Pychyl

Known for:Emotion-regulation model of procrastination — reframing chronic delay as motivated avoidance of task-associated negative affect rather than poor time management

Key findings

  1. 2016

    With Fuschia Sirois, Pychyl published a theoretical review arguing that procrastination is fundamentally an emotion-regulation problem: avoidance reliably produces short-term mood repair, and this immediate reinforcement sustains the habit even when it costs long-term wellbeing. ↗

New York University / University of Konstanz

Peter M. Gollwitzer

Known for:Originator of implementation intention theory — the if-then planning format that links situational cues to pre-decided goal-directed responses, dramatically improving follow-through over goal intentions alone

Key findings

  1. 1999

    Gollwitzer proposed that the if-then plan format ('When situation Y, I will do Z') heightens the mental accessibility of the specified cue, so the behavior is triggered automatically when that cue is encountered — bypassing the need for renewed deliberate effort. ↗

  2. 2006

    With Paschal Sheeran, Gollwitzer conducted a meta-analysis of 94 studies and found d = 0.65 across varied goal domains, establishing implementation intentions as one of the most reliable self-regulation tools in the social-scientific evidence base. ↗
