Subtlety in persuasive technology is difficult to define, measure, and evaluate. It relates to a subtle implementation of persuasive principles in applications but also to a subtle balance, variation, combination, or adaptation of persuasive principles. Understanding subtlety in persuasion benefits the effectiveness of persuasive technology because more intrusive non-subtle persuasive cues can have a direct positive contribution, but at the same time might lead to higher resistance or hesitation to users which has a negative contribution to effectiveness. We explore the notion of subtlety and we propose an attempt to make subtlety measurable by relating it to the psychological notion of reactance. An experiment has been set up to research the proposed coupling. An existing persuasive software product is used as a research carrier. The most important result is that persuasive feedback indeed results in a significant increase in reactance arousal.
