INTRODUCTION

CORE DEFINITION
A search strategy in which different people cover different sources, databases, or angles, and the findings are then shared, deduplicated, and jointly screened. The model addresses the fact that a single searcher has systematic blind spots determined by their background and their habitual sources. The key qualification is that the benefit comes from genuine division and pooling: without distinct assignments the effort duplicates, and without sharing the blind spots remain. Joint screening also raises the reliability of relevance judgments.
SCAFFOLDING EFFECT
Reduce cognitive load
- Assignment split: divide the search by source, database, or angle rather than searching everything together. - Provenance marking: have each searcher record where each finding came from. - Joint screening: merge the results and decide relevance collectively rather than separately.
Anchor fast decisions
Individual searchers work from a limited set of sources and habitual search terms, so their misses are correlated with their own background. Distributing the search across different backgrounds produces a union of coverage that a single searcher cannot reach, and pooling removes the overlaps. Collective screening adds a second benefit, since relevance judgments that are unreliable alone become more consistent when reviewed by several people.
