Yes, this can be a scary topic: machines designed to influence human beliefs and behaviors. But there’s good news. We believe that much like human persuaders, persuasive technologies can bring about positive changes in many domains, including health, business, safety, and education.
We also believe that new advances in technology can help promote world peace in 30 years. With such positive ends in mind, we are creating a body of expertise in the design, theory, and analysis of persuasive technologies, an area called captology.
If the ends are positive, the means can't be bad, right?
