itsual Persona Evidence
Overview
Personas help teams build empathy and focus — only when they reflect real patterns in research. Evidence-light personas become fiction that misguides decisions.
When to Use
- Creating or refreshing personas
- Challenging outdated or political personas
- Linking segment research to design tools
- Aligning product and marketing on who the user is
Core Practices
- Derive personas from clustered behaviors, needs, and contexts
- Cite the studies and samples behind each persona
- Include goals, constraints, and environments — not only demographics
- Separate proto-personas (assumptions) from validated personas
- Retire or revise personas when evidence changes
- Show how each persona should change a product decision
Principles
- A persona without evidence is a stereotype with a name
- Too many personas dilute focus
- Demographics alone rarely predict behavior
- Living artifacts need owners and review cadence
Verification
- Each persona links to research sources
- Distinguishing behaviors/needs are clear
- Teams can name decisions the persona should influence
