Common Ground Building
Updated 2026-08-10
INTRODUCTION
English translation pending.
CORE DEFINITION
A concept from cognitive science and team research describing the shared basis that participants rely on when coordinating. It operates at three levels: a common language or vocabulary, a shared store of experience, and an agreed frame of reference for goals. The core proposition is that much coordination cost comes from mismatched assumptions rather than from disagreement, so building common ground reduces the friction of alignment. The key qualification is that it must be maintained over time.
SCAFFOLDING EFFECT
Reduce cognitive load
- Vocabulary check: confirm that key terms mean the same thing to everyone involved. - Shared reference: point to common examples and documents rather than describing from scratch. - Goal alignment: state the shared objective explicitly before dividing the work.
Anchor fast decisions
Coordination requires each party to predict what the others will do, and those predictions rest on assumptions about shared knowledge. When the assumptions match, messages can be short and implicit; when they diverge, each party misreads the other and effort goes into repairing misunderstandings. Building the shared base explicitly shifts effort from repair to work.
