Persona stacking combines multiple roles or lenses in one prompt to get richer, more nuanced output.

Examples

• "Act as both a marketing expert AND a data scientist analyzing this campaign"
• "Review this code as both a security engineer and a performance engineer"
• "Evaluate this business plan as an optimistic founder AND a skeptical investor"

Why It Works

Different perspectives surface different insights. Stacking forces the AI to hold multiple viewpoints simultaneously — just like a good consultant would.
