Optimized but Unowned: How AI-Authored Goals Undermine the Motivation They Are Meant to Drive

Don't delegate goal-setting to AI if behavior change matters. The quality-motivation dissociation is real: better-formed goals produce worse outcomes. Especially avoid for users with low self-efficacy—they experience the steepest ownership erosion.
AI tools can generate objectively better goals than users write themselves, but motivation depends on psychological ownership, not just goal quality. Does optimization come at the cost of commitment?
Method: LLM-generated goals scored higher on SMART criteria (d = 2.26) but participants reported lower psychological ownership (d = 1.38), commitment (d = 1.19), and perceived importance (d = 1.13). At two-week follow-up, 72.8% of self-authored participants acted on two or more goals versus 46.6% in the LLM condition. Mediation analysis confirmed ownership—not objective quality—drove every downstream motivational and behavioral outcome.
Caveats: Two-week follow-up only. Longer-term adaptation or ownership recovery mechanisms unexplored.
Reflections: Can hybrid authorship models (AI suggests, user edits) preserve ownership while improving goal quality? · Does repeated exposure to AI-authored goals eventually restore ownership through habituation? · Do ownership effects generalize to other identity-relevant tasks like value articulation or career planning?
