BJ Fogg ran a free program for eight years before anyone paid him for it
The Stanford researcher personally coached more than 40,000 people in habit design, unpaid, because the data coming back was too useful to stop.
In 2011, BJ Fogg put a free five-day habit program online. Thousands enrolled each week. He coached participants himself—every day, including vacations—for years, with no fee, because he was running live experiments on his own research.
The finding that came back most consistently surprised him. People were not failing at habits because of laziness or lack of motivation. They were failing because they were starting too large.
Fogg's model holds that any behavior requires three things to converge at once: motivation, ability, and a prompt. Most habit advice optimises motivation and ignores ability. Fogg went the other direction. Make the behavior so small that motivation becomes almost irrelevant. Two push-ups. One sentence in a journal. Floss a single tooth.
The second insight was about attachment. A new behavior lodges more reliably when it is anchored to something that already happens consistently—not to a time of day or a good intention, but to an existing action. After I pour my morning coffee, I will. After I sit down at my desk, I will. The existing routine becomes the scaffold.
By the time Tiny Habits was published in 2019, Fogg had more than 500,000 data points from eight years of iterative field research behind its central claims.
