What is a theory of change

A theory of change is a written-down argument: if we do X, we expect Y to happen, because of Z. Tactics without a theory of change are just calendar items.

Most organizing failures are not tactical failures. They are theory-of-change failures. A town hall that draws a packed room but does not move a single decision-maker did not fail because the room was small. It failed because nobody could name what success looked like before the doors opened.

A theory of change is the explicit chain that connects what you do to what you want to change in the world. It has four links: problem, root cause, strategy, and outcome.

Problem is the observable harm. In Georgia post-Callais v. Landry, the observable harm might be: a redrawn map that splits a Black majority county across three congressional districts, diluting voting power. The problem is concrete, named, and verifiable from public data.

Root cause is the upstream condition that produced the problem. The root cause of the split county is not the map itself — the map is the symptom. The root cause is that the redistricting committee held two public hearings, both in the state capitol, both during work hours, with no Spanish interpretation, in a state where 10.5 percent of the population is Latino and most directly-affected counties are 60+ miles from Atlanta.

Strategy is your tactic for changing the root cause. A county-level town hall held in the affected community, at 6:30 p.m., with interpretation, and a county captain who has already collected 200 verified constituent stories, is a strategy that directly addresses the root cause.

Outcome is what changes if your strategy works. The outcome is not 'we held a town hall.' The outcome is 'four county commissioners and one state representative publicly committed to opposing the redrawn map and we collected 142 new captain pipeline contacts in counties that had zero coverage.'
