How Can Persuasive Technology Help People Choose for Themselves?


Persuasive technology is used when it is known in advance what the

person in question should be persuaded to do. The job of helping people to choose for themselves what they want to do, in accordance with their own values, tastes, past experience, and capabilities, has been left to other types of interactive system, such as those for decision support or recommendation. But there are reasons

why persuasive technology researchers might consider applying their skills to the

challenge of helping users choose for themselves:

  1. A lot of the innovative techniques developed in persuasive technology can be adapted to yield new ways of supporting choosing. Examples are techniques for monitoring behavior, for simulating the consequences of possible actions, for enforcing commitment strategies, for mediating social influence, and for communicating with users at opportune times and places.

  2. While users of persuasive technology are doing what they have been persuaded to do, they often need to make nontrivial personal choices about exactly how to do it; their overall success and satisfaction will be affected by how well they make these choices.

This talk argues for these claims with reference to concepts and results from the psychology of everyday decision making, and it illustrates them with examples  from past and ongoing research and practice.

Persuasive Technology or Explorative Technology?


Persuasive technology is technology that is intended to change attitudes and/or behaviors using persuasion. An issue with such technology is it

pre-supposes that individuals must be convinced to change their attitude or

behavior. In contrast, explorative technology is technology that is intended to

help users explore and understand information about themselves to support self-reflection and to identify opportunities for behavior change. In this talk, I will describe the differences between such technologies, and argue for the need to invest more effort in explorative technologies through the discussion of a series of case studies.
