Comparison
Imagine All The People vs Human Panel
Measure real people or simulate a decision before acting?
Human panels remain irreplaceable when you need to measure what real people say or do. Imagine All The People answers a different question: what could happen if we change the decision, the message, the price or the scenario?
Four differences, stated plainly.
Thesis
A panel measures what is. A simulation explores what could be. These are not the same questions.
- Human panel
Answers from real people.
Imagine All The PeopleAnswers from synthetic individuals belonging to a statistically constructed population.
- Human panel
The sample is recruited, then generally weighted or calibrated on selected reference dimensions.
Imagine All The PeopleThe population distribution can be built under a large number of marginal and cross constraints.
- Human panel
A new hypothesis may require a new wave or a new study.
Imagine All The PeopleSeveral scenarios can be replayed on exactly the same synthetic individuals.
- Human panel
Measuring what is.
Imagine All The PeopleExploring what could be.
What changes, dimension by dimension.

The issue is not only sample size. It is the structure of the population.
In a human panel, representativeness is generally obtained through recruitment, quotas, weighting or calibration. Imagine All The People directly builds a population distribution from reference data, probabilistic dependencies and marginal or cross constraints.
This difference matters as attributes and constraints multiply.
Panels frequently use weighting or calibration methods, including raking, to bring the sample closer to reference distributions. Imagine All The People makes it possible to control a much richer set of explicitly modelled statistical dimensions.
- 40attributes in the benchmark
- 19,409statistical constraints
- −73%error vs raking in the benchmark
Benchmark of statistical fidelity in population construction. It does not measure the behavioural validity of answers.
An illustrative example.
Decision
Should we raise the price of an offer by 8%?
Human panel
Question a sample of customers and prospects about their reaction to the increase.
Imagine All The People
Build the population concerned, test several levels of increase and several trade-offs, then replay each scenario on the same synthetic individuals.
The panel measures a real reaction to a given question. The simulation quickly explores several possible futures.
Each approach has its own domain of relevance.
Choose a human panel if…
- you need to measure real attitudes;
- the result must come from people who were actually questioned;
- the observed behaviour is itself the evidence you are looking for.
Choose Imagine All The People if…
- you want to compare many options before acting;
- you need populations that are hard or expensive to question;
- you want to replay the same decision continuously.
Combine both if…
- you want to calibrate or validate a simulation with human observations;
- you want to use simulation to prepare and deepen a real study.
What these pages do not claim to prove.
The statistical robustness of the population does not automatically transfer to behavioural answers. Building the population and validating the answers are two distinct layers.
