Data grounding is what separates a useful synthetic audience from a generic persona prompt. It gives the simulation a documented basis: what the audience is meant to represent, which evidence supports it, and what remains uncertain. This FAQ explains how to ground [Synthetic Audiences](https://getminds.ai/glossary/what-are-synthetic-audiences) responsibly for market research, campaign testing, product concept testing, and segmentation work. ## Basics ### What is data grounding for Synthetic Audiences? Data grounding means giving a synthetic audience documented context instead of relying on a generic persona prompt. Grounding can include: - Approved research summaries. - CRM segment patterns. - Survey findings. - Interview themes. - Support or sales objections. - Public market data. - Category reviews and language patterns. - Clearly labeled expert assumptions. The goal is not to feed every available source into a model. The goal is to give the synthetic audience enough relevant context to answer the research question in a way that can be inspected. ### Do Synthetic Audiences need first-party data? Not always. First-party data can improve relevance when it is approved and appropriate, but it is not the only grounding path. A synthetic audience can also be grounded in prior research, public category evidence, expert assumptions, or a carefully written research brief. The key is transparency: the team should know what the simulation is based on and what it is not based on. ## Source Quality ### What makes a grounding source useful? A useful grounding source is relevant to the decision, current enough for the category, specific to the audience, and allowed for the study. Strong grounding sources answer questions like: - What does this audience already do? - What alternatives do they consider? - What objections have appeared before? - What language do they use? - Which constraints shape the decision? - Which assumptions are still unproven? ### What should not be used as grounding data? Do not use raw private messages, credentials, confidential personal data, unsupported customer claims, or data the team does not have rights to use. Sensitive source material should be summarized and approved before it becomes grounding context. A synthetic audience does not need raw private material to be useful. It needs relevant, scoped, reviewable context. ## Validation ### How do you know if grounding is good enough? Use a simple check: - The audience definition is specific. - The grounding sources are relevant to the decision. - Unsupported assumptions are labeled. - The prompt does not force a desired answer. - The output can be compared against known evidence or follow-up validation. If these checks fail, improve the audience before running more simulations. ### Can grounded Synthetic Audiences replace real data? Grounding makes a simulation more useful, but it does not turn the output into final proof. Real respondents, behavioral data, or specialist statistical methods are still needed when the decision requires representative evidence, legal proof, regulated claims, physical product experience, or final pricing confidence. ## Related - [How to build Synthetic Audiences for market research](https://getminds.ai/guide/how-to-build-synthetic-audiences-for-market-research) - [Synthetic Audiences validation checklist](https://getminds.ai/research/synthetic-audiences-validation-checklist) - [Synthetic Audiences methodology](https://getminds.ai/research/synthetic-audiences-methodology) - [Synthetic Audiences vs surveys](https://getminds.ai/comparison/synthetic-audiences-vs-surveys) ## **Frequently asked questions** ### **What is data grounding for Synthetic Audiences?** Data grounding means giving a synthetic audience documented context instead of relying on a generic persona prompt.
