Do affects affect you or do you affect affects? A closed-loop in positive technology

Positive psychology arises from Seligman, who coined the phrase “learned helplessness” to describe how negative thoughts can lead to clinical depression. A better explanation, however, derives from the “chain reaction” concept in the physics of complex systems, often defined as positive feedback that leads to self-amplifying effects. The same concept may justify helping technology to instill positive chains of behavior that then lead to well-being.
