Two-Minute Starts

Working adults do not fail for want of goals. They fail at the first step. Across 642 independent tests, if-then planning improved outcomes by d = 0.36 (95% CI 0.33 to 0.40); the 2006 initiation slice remains d = 0.61, but no trial yet isolates whether shrinking the first step adds to that plan. Gollwitzer and Sheeran’s 2006 synthesis of 94 tests reported a medium-to-large effect on goal attainment (d = 0.65). Later, larger, more field-heavy reviews revised that figure downward. Behaviour-change effects now sit nearer d = 0.27. Workplace samples sit at d = 0.26. This paper asked a narrower question. Does making the first move tiny add anything to an if-then plan? We searched PubMed, PsycINFO, Scopus, Web of Science, Google Scholar, CTRI, ClinicalTrials.gov and OSF preprints from 2006 to 2026. We looked for randomised and controlled trials in adults that compared implementation intentions, tiny-step techniques, or both, against goal intention or control. Primary outcomes were initiation rate and goal attainment. A planned random-effects meta-analysis of the additive contrast could not be performed. We found no factorial trial that held the if-clause constant and manipulated only the size of the then-clause. Tiny-step trials exist, but they are few, measure the wrong outcomes, or have not been published as results papers. A pooled increment is not yet possible. What can be said is more modest and more useful. If-then plans still help people start. Specificity of the then-clause matters. Rehearsal and boosters matter. Digital delivery is weaker than face-to-face coaching. No Indian trial of either technique on task initiation in working adults has been registered or published. For an Indian workplace programme the honest design is: write one if-then sentence, shrink the first rep to two minutes, and do not claim an extra d that the literature does not contain.
