Force field analysis for one stuck goal: a 7-day plan

A sewing-machine operator in a factory studied by Alex Bavelas had a strange record. Her average output was above the group’s, but her speed swung wildly from week to week and she was often absent. Then the factory introduced pacing cards. Her output climbed to an exceptionally high level, and the swings and the absences dropped off at the same time.

Kurt Lewin used her chart in “Frontiers in Group Dynamics” (Human Relations, 1947), reprinted in Field Theory in Social Science (Harper, 1951, edited by Dorwin Cartwright), which is the version I read. His explanation is the core of force field analysis, and the reason this how-to exists. Any steady level of behavior, whether a factory’s output or your three-runs-a-week plan that keeps landing at one, sits between forces pushing it up and forces holding it down. You can raise the level by adding push or by removing resistance. Lewin wrote that the first route leaves you at the new level “accompanied by a state of relatively high tension,” the second with relatively low tension, and that high tension travels with “greater fatigue, higher aggressiveness, higher emotionality, and lower constructiveness.”

So for a personal goal, force field analysis means listing what pushes you toward it and what holds you back, then spending the week weakening the strongest restraint instead of piling on more motivation. Here is that week, step by step.

Step 1 (day 1): pick a wake time and a witness

Choose the hour you’ll get up for the next seven mornings and put the goal’s daily work in the hour after it. If you don’t know what time you can actually hold, the median of your last seven real wake-ups is a better starting point than an aspirational number.

Then choose one person who will know whether you got up. DontSnooze can stand in for the daily text: the friends you choose hear about it only on the mornings you don’t show that you’re up. A fixed start time removes one of the most common restraints before you’ve even listed it, which is that the work has no slot. Raymond Chandler’s write-or-nothing hours are an old answer to that particular restraint.

Step 2 (day 1): write the goal as a level you can count

Lewin’s examples are all levels: a sewing factory’s hourly output, how many households increased their fresh-milk consumption, how much hostility a scapegoated child absorbed in a club. Write two numbers in one unit. “Get fit” has no level. “Run 1 time a week now, 3 times a week by the end of the month” does.

Step 3 (day 2): fill both columns and score every force

Draw a line down a page. On the left, write the drivers; on the right, the restraints. Score each from 1 (weak) to 5 (strong). The illustrative example below is a made-up runner, not anyone’s real data.

Driving forces	Score	Restraining forces	Score
Doctor mentioned blood pressure	4	Shoes and clothes are in the basement	3
Race with a friend in spring	3	Kids’ school run fills 7:30 to 8:15	5
Likes how sleep improves after runs	2	Left knee aches on pavement	4
		Runs alone, no one notices a skip	3

Expect the right column to feel harder to fill. People tend to explain a stuck goal by weak desire, and Lewin’s text pushes the other way: he argued that what we call “ability” or “difficulty” belongs among the restraining forces, things that oppose movement without creating any.

Step 4 (day 2): look for the restraint you won’t admit

In Lewin’s factory analysis, one force keeping output down was the workers’ fear that a temporary burst of speed would lead the foreman to demand the higher pace permanently. Reaching the goal had a cost.

Ask the same of yours. If you hit three runs a week, does that become the new floor you’re expected to hold? Does finishing the draft mean someone finally reads it? Write the answer in the right-hand column and give it a score. This is often the 5 you missed.

Step 5 (day 3): cut the strongest restraint and add no new push

Take the highest-scoring restraint you can actually change this week, and change one concrete thing. In the example, the school run scores 5 and can’t move, so the runner moves the run to before it, at the new wake time, and lays the shoes by the bed to knock out the basement trip.

What you skip matters as much. No new reward, no motivational playlist, no raised target. Those are added driving forces, and in Lewin’s model they raise the level by raising the strain. Lewin did not describe Bavelas’s pacing cards in detail, but he read the results as coming “at least in part” from reducing forces that kept production down rather than adding new ones. For another case of a small barrier mattering more than a big push, see the Yale study where a campus map outperformed fear.

Step 6 (days 3 to 6): record the level every day

Each night, write the number (did you run, how many pages) and one line on whether the day felt strained or easy. The second line is your tension reading. Writing progress down is itself one of the better-supported goal habits; the evidence on monitoring found the effect was larger when progress was recorded and reported to someone.

That second line is also the early warning. A good number paired with “strained” three days running means you raised the level by pushing, which is the pattern Lewin expected to break down.

Step 7 (day 7): redraw the field

Rescore every force from scratch. Compare four days of numbers with the starting level from step 2. Three outcomes are common:

1. The level rose and the days felt easy. Keep the change and pick the next restraint.
2. The level rose and the days felt strained. You probably added push by accident; look for the pep talk or the self-imposed penalty and remove it.
3. The level didn’t move. The restraint you cut was not the strongest one, or a hidden one from step 4 is still there. Move to the next 5.

Lewin’s nervous operator is a useful picture for week two. Her gain was not just a higher number but a steadier one, with fewer of the bad weeks that had pulled her average down. A week where you ran three times and the Thursday entry reads “easy, shoes were already out” is the result to look for, more than a week where you ran four times and wrote “dreading tomorrow.”
