An overview of PurplePath behaviors and techniques for achieving them.

PurplePath Behavior Overview

Purple Path behaviorIf you want someone to increase the intensity or duration of a behavior forever, you are seeking a Purple Path Behavior.

Examples include:

  • Health: Exercise 10 minutes more each day, from now on.
  • Environment: Eat more¬†fruits and vegetables each day into the future.
  • Commerce: Save 10% more of your paycheck each month forever.

Many people seek Purple Path behaviors. They are already doing something good, like exercising, and they are ready to take it to the next level. This increased intensity or duration of a familiar behavior (like exercise) is what Purple Path is all about.

To achieve a Purple Path Behavior, it is necessary to alter at least one element from the Fogg Behavior Model:

  1. Increase the number of triggers leading to the desirable behavior.
  2. Enhance ability to perform the behavior (make it easier to do)
  3. Amplify motivation for doing the behavior with intrinsic and extrinsic motivators.

Our Resource Guide for Purple Path Behaviors explains specific techniques and tools for achieving increasing the intensity of a behavior one-time. It also highlights successful programs and online systems that exist for this purpose.

About Resource Guides

Our Stanford team created these Resources Guides to help people working on behavior change projects. We can make it easier for you to:

1. Learn about a specific type of behavior change

2. Create solutions for achieving that behavior

In the past, most designers and researchers guessed at solutions for changing behavior. And frankly most attempts failed. Today, rather than guessing at solutions, people who use our Resource Guides will have clear guidance.

Our Stanford team will continue to improve each of the 15 Resource Guides.  We welcome your input.

The Behavior Guides were created in 2010 and we are no longer updating or selling them.

There is still lots of useful information in these guides. If you’re interested in obtaining a specific guide, please email us (behaviorwizard@gmail.com) and let us know in which guide you’re interested and why. We may be able to share a copy with you.

We hope you’ll also benefit from our more recent behavior design projects at: http://captology.stanford.edu.
