How is a synthetic panel different from a traditional panel?

A traditional panel is recruited real people, available in 1 to 4 weeks at a per-complete cost. A synthetic panel is composed in minutes, is rerunnable on identical parameters, and reaches low-incidence segments that are expensive to recruit. Traditional panels remain the standard for defended claims and rare-event incidence.

How large should a synthetic panel be?

Size it by the segment cuts you intend to read, the same way you would size a live cell. A 100 response study reads four segments comfortably and twelve segments poorly.

How much does a synthetic panel study cost?

A 100 response, 10 question study is 2,100 credits, about $33 on the Growth plan, against $86 to $143 for the same study on a DIY live panel at Prolific's published rates (retrieved 2026-08-11).

Are synthetic panels accurate?

Judge accuracy from a published held-out benchmark against a named external survey. PersonaHive publishes its comparison against the U.S. CFPB 2024 National Age-Friendly Banking Survey, with method and limitations documented. Agreement is strongest on directional and comparative reads and weakest on absolute incidence.

What Is a Synthetic Panel?

TL;DR: A synthetic panel is a composed set of AI personas, each calibrated to national census distributions, that answers a research instrument in place of recruited respondents. Panels are assembled per study to match a target market, run in minutes rather than weeks, and can be rerun on identical parameters for controlled comparison. They are the right instrument for exploration, screening, iteration, and tracking cadence, and the wrong instrument for regulator-bound claims, rare-event incidence below five percent, and longitudinal behavior change in the same individuals.

Key Facts

Definition: A per-study set of census-calibrated AI personas that responds to a research instrument in place of recruited respondents.
Composition: Matched to national census distributions for the selected country, across 20+ verified attributes per persona.
Cycle time: Minutes to hours, against 1 to 4 weeks for a traditional panel including recruitment.
Cost: 2,100 credits for a 100 response, 10 question study, about $33 on the Growth plan, against $86 to $143 at Prolific's published rates (retrieved 2026-08-11).
Not suitable for: Regulator-bound claims, rare-event incidence below 5%, longitudinal change in the same individuals, and physical product interaction.

What is a synthetic panel?

A synthetic panel is the synthetic equivalent of an online research panel: the set of respondents a study is fielded to. The difference is that the respondents are AI personas grounded in national census data, country-specific, built from aggregated public statistics, and validated against real surveys, rather than people recruited from a marketplace.

The panel is composed per study. Rather than drawing a sample from a standing pool and hoping the quota fills, the researcher specifies the market and the segment structure, and the panel is assembled to match the documented distributions for that market.

How is a synthetic panel composed?

Composition runs in four steps.

1. Define the market and the population frame, which fixes the census distributions the panel is matched against.

2. Specify segment structure, the cuts you intend to read at the end. This drives panel size, because every cut you plan to report needs enough respondents behind it.

3. Sample personas against the target distributions, including at the distribution extremes rather than only around the mean, so the panel retains internal variance instead of collapsing to an archetype.

4. Deploy the instrument. Each persona answers with a written rationale attached, which is what makes an unexpected result diagnosable rather than merely surprising.

How should a synthetic panel be sized?

Size by the cuts, not by instinct. If the read is a single overall score, a small panel suffices. If you intend to compare four segments, each segment needs enough respondents to support a read on its own, and a 100 response panel handles that comfortably. Twelve segments on the same 100 responses gives you eight respondents per cell, which is a qualitative signal presented as a number.

Because cost scales with responses and questions, oversizing is cheap relative to live fieldwork but not free. The discipline that matters is deciding the reporting cuts before the panel is composed.

Where does a synthetic panel not apply?

Four cases require live respondents regardless of calibration quality. Regulator-bound and legally defended claims, which need fielded research with documented sampling. Rare-event incidence below five percent, where the signal lives in cases a model will not reliably produce. Longitudinal behavior change tracked in the same individuals over time. And anything mediated by the body: taste, feel, in-home usage, physical prototype interaction.

A synthetic panel used inside those boundaries is a fast research instrument. Used outside them, it is a confident guess.

How do synthetic and traditional panels work together?

The pattern most teams settle on is synthetic upstream, live downstream. Screen wide and iterate on the synthetic panel, where reruns are cheap, then take the surviving one or two candidates into a properly powered live cell for the go/no-go or the citable number.

The live study ends up smaller and sharper than it would have been as the only study, because the synthetic phase already eliminated the questions that did not need a live answer. That is where the budget saving actually lands, not in the line item for a single study.
