If you worked in Marketing ten years ago, you will remember personas as laminated sheets pinned to office walls or big posters on meeting room boards. "Sarah, 34, SME sales leader, married, plays
volleyball." We'd assign statements, likes and dislikes, and discuss how to reach these customer clusters and hope these fictional characters somehow captured the complexity of real human
behavior.
The methodology is still valid, but we can do it much better now.
AI has fundamentally changed how we can understand and predict human behavior. Recent breakthrough research from Stanford and Google DeepMind shows that AI agents, trained on just two
hours of interview data per person, can predict human responses with 85% accuracy - matching how consistently people replicate their own answers two weeks later. We're not talking about simple
demographic matching anymore. We're talking about digital twins that capture the nuanced decision-making patterns of real individuals.
The AI Persona Revolution
The Stanford study involved 1.052 Americans across diverse demographics. Researchers conducted in-depth interviews, then created AI agents that could simulate each person's attitudes, personality traits, and behavior in social experiments. As a result, the AI personas didn't just match surface-level preferences - they replicated complex decision-making in economic games, predicted personality test outcomes, and accurately forecasted responses to political and social surveys.
UPDATE JULY: A group of international researchers at the Helmholtz Institute for Human-Centered AI in Munich fine-tuned Meta’s Llama by training it on 160 psychological studies, involving more than 10 million choices. The model, called Centaur, picked up on behavioral patterns that are common across humans, leading to stunningly correct predictions of people’s choices in tasks it had not been trained on.
But you don't need to create a comprehensive psychological model to generate actionable intelligence when working with stakeholders, designing experiences, or managing organizational change.
Three application ideas for your work
1. Design Thinking Idea Testing
AI personas enhance the Design Thinking process. You can iterate on ideas with diverse AI personas representing your actual product user base, identifying potential friction points and opportunities before investing in prototypes. Imagine running design sprints where your personas can actually respond to your concepts in real-time. Instead of asking "What would Sarah think of this feature?" you can ask Sarah's AI twin, trained on customer data and identified behavior patterns.
2. Communication Strategy Validation
Often you carefully craft a message or presentation, launch it, and discover only later that it completely missed the mark with certain stakeholder groups. AI personas offer a preview function for all kinds of communication strategies.
Before pitching business proposals in the board, publishing policy announcements, or marketing campaigns, you can test them with AI personas representing your target audiences. These aren't generic demographic clusters - you can design specific roles with any LLM to capture how they process information, what triggers their concerns, and what language resonates with their values.
In their newsletter Personal Math, Greg Shove & Taylor Malmsheimer write about leadership and for better decision making. To prepare a board presentation, they suggest to set up multiple AI personas with conflicting objectives: “For this decision, I want you to simultaneously represent three perspectives: 1) Our head of growth who wants to maximize user acquisition at all costs, 2) Our CFO who’s paranoid about runway, and 3) Our lead engineer who’s concerned about technical debt. Each should make their strongest case without compromising.” If you set up a project in ChatGPT or Claude, you can run your content through a group of stakeholders to work through conflicting or adverse opinions tactically.
3. Internal Stakeholder Modeling for Transformation Success
Organizational change fails when leaders underestimate resistance patterns and stakeholder dynamics. AI personas can model key internal stakeholders - from skeptical middle managers to enthusiastic early adopters - helping you predict roadblocks and design targeted engagement strategies.
Think about your last major transformation. Could you have benefited from understanding how different personality types and value systems within your organization would respond to specific change messages?
AI personas make this possible without the political complexity of directly interviewing every stakeholder group. By adding content like systemic principles and questions to your chatbot project you get even more thoughtful outcome.
How To Create Valuable AI-Personas
Creating personas with Stanford-level accuracy requires deep interview methodology. Their approach involved two-hour qualitative interviews, adaptive follow-up questions, and validation against social science benchmarks. Platforms like Delve.ai offer synthetic personas from existing customer data, e.g. for marketing campaigns. But you don't always need this level of complexity.
The Pragmatic Approach: LLM-Generated Personas
For most business applications, you can create remarkably useful personas through structured dialogue with AI. You describe stakeholder characteristics to an LLM and iteratively refine the persona through conversation.
Here's how this works in practice:
- Prompt the Foundation, e.g. "Create a persona for a middle manager in manufacturing who has been with the company 15 years, is skeptical of new technology, values job security, and has seen multiple failed transformation initiatives."
- Develop Depth Through Dialogue Ask your LLM to elaborate on this person's communication preferences, decision-making triggers, and likely objections to change. The conversation builds nuanced understanding. Remind your bot to remember all details or use a canvas in ChatGPT or Claude.
- Generate Visuals Use AI image generators with specific prompts: e.g. "Professional headshot of a 45-year-old manufacturing manager, confident but cautious expression, industrial background, realistic style." These visuals make personas tangible for your team. Also provide a name and biographic details, like in the traditional persona work.
- Test Communication Present draft messages, emails, or presentations to your AI persona and ask for realistic reactions. "How would this change announcement land with you? What concerns would you have?"
All you need is
- an advanced LLM (Claude, ChatGPT, etc.) for persona dialogue creation.
- AI image generators (like Midjourney, or LLM-integrated image creation features in Google Gemini 2.5 Flash or Chat GPT 4o) for visual representation.
- templates for thoughtful prompting and iterative refinement, which your team can reuse across projects.

AI personas aren't new, but they are easier to use than ever. From innovation workshops to strategic transformation and comms campaigns, they offer a proactive, creative, and data‑driven way to really understand the humans on the other side.
If you're curious about how to apply this I'd love to explore your specific context and use cases.
