Product psychology connects customer evidence, behavior diagnosis, perception, journey design, and ethical review. Use this topic when you need the complete workflow. For a specific design problem, load the owner topic below so the MCP returns the focused guidance at the moment it is needed.

|---|---|---|
| The team is guessing what customers want | understanding-users | Reconstruct a Customer Story |
| Users are not taking an intended action | behavior-change | Diagnose Motivation, Ability, and Prompt |
| A flow loses momentum partway through | behavior-change | Track Perceived Value Through a Flow |
| Important information is ignored | cognitive-laws | Block: Pass Attention Filters |
| Users notice information but misunderstand it | cognitive-laws | Interpret: Establish the Right Frame |
| Users understand the goal but action still feels hard | behavior-change | Reduce Ability Cost Before Pushing Motivation |
| Completion feels uncertain or forgettable | notifications | Store: Make the Ending Memorable |
| The roadmap needs journey priorities | design-process | Map the Customer Journey |
| A review needs a shared decision rationale | design-process | Communicate Decisions to Stakeholders |
| A nudge may trade trust for conversion | anti-patterns | Manipulation & Ethics |
Run the Workflow
- Reconstruct a recent customer story and separate validated evidence from assumptions.
- Diagnose motivation, the binding ability constraint, and prompt timing.
- Track perceived value through the flow and apply the B.I.A.S. loop: Block, Interpret, Act, Store.
- Map the journey's peak, pit, largest jump, largest drop, and meaningful transitions.
- Connect the customer story, gap, principle, intervention, outcome, measure, and unknowns.
- Test the intervention for informed choice, second-order harm, agency, and long-term trust.
Product Psychology Review Checklist
- The work begins with a recent customer story, not a funnel metric or assumed bias
- Motivation, ability, and prompt timing are diagnosed separately
- Friction is removed before reminders or nudges are added
- Important information passes attention filters and uses an honest frame
- Completion clearly communicates what changed and what comes next
- Journey priorities focus on defining moments instead of every minor inconvenience
- The decision names its evidence, outcome, measure, guardrail, and unknowns
- Scarcity, comparisons, defaults, and social evidence are authentic
- Users would make the same choice with full information
- The design preserves control, a meaningful exit, and long-term trust
