They answer different needs.
Real interviews generate evidence from people. Simulations estimate responses through a model. Both can support a decision, but they should not be presented as interchangeable.
| Question | Real interviews | Simulations |
|---|---|---|
| What do you get? | New responses from recruited people. | Estimated responses from a buyer model. |
| Best starting point | A gap that needs fresh evidence. | A direction or idea to explore. |
| What matters? | Audience fit, study design, question wording. | Audience fit, model relevance, validation. |
| What is not guaranteed? | That participants represent every buyer. | That an estimate predicts future behavior. |
Start with the decision.
If the question concerns an audience you do not yet understand, new research is often the right foundation. If you already have meaningful understanding and want to explore several directions, a simulation can help focus the work.
For a high-impact decision, use simulations to identify the alternatives and uncertainties worth investigating, then ask real people the questions that need stronger evidence.
Make it a cycle.
Interview to learn. Simulate to explore. Interview again when the next question requires it. Gather connects those steps around a brand-specific model that teams and agents can continue querying.
