Fillip Kosorukov — B.A. Psychology, summa cum laude, University of New Mexico (2020) and research collaborator with the MATEO Lab (Motivation, Addiction, and Temporal decision-making in Emerging-adult Outcomes) — presents a four-criterion framework for designing behavior-change products that actually produce durable effect. Drawn from three years of applied psychology research at UNM and worked through three shipped products: Resilience (gamified reentry support at resiliencegame.org), FixMyRecord.io (reputation repair and data broker removal), and LocalMention.io (AI visibility audits). The deck covers: felt competence vs. compliance loops; intervention timing at the moment of choice; honest, specific, near-term feedback; and designing lapse-recovery as a first-class product concern. For founders, product designers, and applied researchers building at the intersection of psychology and technology. Written for operators who want to ship products that change what users do, not just what users say they do.
