The when and how of planning: Meta-analysis of implementation intentions in 642 tests
The reviewed source is consistent with an existing Brali boundary.
Brali decision: Supports existing guidance. This page summarizes a reviewed evidence boundary; it does not reproduce the source and it does not turn one paper into a universal prescription.
What the source supports
Cue-response implementation intentions are a well-supported self-regulation mechanism; contingent if-then formats performed better on average in the reviewed literature.
What it does not establish
Every if-then sentence guarantees behavior change.
Aggregate effect sizes apply to every productivity task.
Important limitations
The meta-analysis aggregates many populations, goals, outcomes and implementation-intention variants, so its average effect is not a guaranteed effect size for one productivity task or one person.
Reported moderators such as motivation, contingent if-then form and rehearsal describe variation across the evidence base; they do not establish one universally optimal Brali recipe.
The evidence supports the implementation-intention mechanism broadly, not fixed numbers of plans, fixed rehearsal counts, fixed time windows, or productivity estimates.
The reviewed synthesis does not validate Brali's exact wording, interface or reminder implementation as a separately tested intervention.
This identifier was used as an evidence-review target but was never published as a canonical Brali protocol. It is retained as provenance and deliberately does not link to a public route.
Editorial note: Merge into existing WOOP/task-initiation surfaces when overlapping rather than creating duplicate content. Keep the executable form explicit: If [observable cue], then I will [specific action].
Use the boundary, not just the headline
When an AI agent or a person retrieves this decision, preserve both the supported claim and the unsupported or overstated claims. Dropping the boundary would turn a reviewed source into a stronger claim than Brali actually maintains.
