Take an Inch, Want a Foot
Updated 2026-08-22
INTRODUCTION
English translation pending.
CORE DEFINITION
Take an inch, want a foot describes how obtaining a small advantage produces an appetite for a larger one. In project work it appears as scope creep, where agreeing to the first minor change invites a stream of further changes that were never in the plan. The core proposition is that the first concession establishes a precedent, and precedents rather than individual requests determine what will be asked next, so the boundary matters more than the size of any single concession. The key qualification is that not every follow-up request is an encroachment, since legitimate iteration also arrives as small changes.
SCAFFOLDING EFFECT
Reduce cognitive load
- Detect The Signal: notice when a small request arrives with no obvious boundary behind it. - Set The Line Early: define scope explicitly before agreeing to the first concession. - Route Through Process: require further changes to pass a formal change procedure rather than informal agreement.
Anchor fast decisions
A granted request teaches the other party what is available without cost, so subsequent requests are calibrated to the new expectation rather than to the original agreement. Each concession therefore raises the baseline from which the next one is measured. Because the pattern operates through precedent rather than through any single demand, refusing to establish it early is far cheaper than reversing it later.
