Machine learning yields new insights about habit formation
Hello from the Behavior Change for Good Initiative. If you’ve ever wondered how long it takes to form a habit, you may be interested in our most recent publication, which came out earlier this month in the Proceedings of the National Academy of Sciences…
Is There a “Magic Number” of Days It Takes to Form a Habit?
Led by Anastasia Buyalskaya, Hung Ho, and BCFG Team Scientist Colin Camerer, our latest paper tackles this question by applying machine learning to 52 million observations of people’s gym attendance and hand-sanitizing decisions. Contrary to popular belief, we find that there is no magic number of days it takes to form a habit. Instead, it depends heavily on the person and the situation. It takes months, on average, to form a gym-going habit but only weeks, on average, to habituate to hand sanitizing in hospital settings. However, these averages mask enormous differences between people. You can read more about these findings in our just-released paper in the Proceedings of the National Academy of Sciences.
Register for Our Next Behavioral Science Authors Event Featuring Adam Alter
New York University Professor Adam Alter will discuss his new book Anatomy of a Breakthrough with Dave Nussbaum of Psychgeist Media on Friday, April 28th at 12 PM ET. Anatomy of a Breakthrough unpacks why people become stuck and the “unstickers” they can leverage to continue making progress toward their goals.
Recordings from our previous Spring 2023 events, including the most recent discussion with Professor Uri Gneezy (author of Mixed Signals) and Professor Silvia Saccardo, can be viewed anytime on the BCFG YouTube Channel.
