Apply PDSA to a behavior you want to build or break

Treat habit formation as a series of small experiments rather than a commitment you either keep or blow.

Why it works

Framing a new behavior as a committed identity ("I am going to exercise daily forever") creates binary success-or-failure outcomes. Framing it as a PDSA experiment ("I predict that if I lay out my shoes the night before, I will exercise three of five mornings this week") makes any result informative rather than a verdict on character. This reframing reduces shame and increases the willingness to keep iterating after a missed attempt.

How to do it

1. Pick one behavior change you want to test this week.
2. Write a specific prediction: "If I do X, then Y will happen [n] times."
3. At the end of the week, score the result honestly and change exactly one variable for the next week.

Evidence

Framing goals as experiments rather than commitments is consistent with implementation-intention and self-compassion research, which both find that rigid all-or-nothing frameworks increase shame and reduce persistence after setbacks. (mechanistic)

The PDSA framing for habits is an applied extension of the industrial method; direct comparative trials are not available.

Common mistake

Running the experiment but never writing the prediction, which means the end-of-week review is a feeling ("I did okay") rather than a comparison point with information in it.
