A modeled public · United States + world
Model how public reaction could move.
Pheme is a simulation—not a poll. Ask a question, test a scenario, and inspect how modeled reactions vary by place.
Named public demographic and geographic inputs.
A question or explicitly hypothetical scenario.
Estimated patterns, shown with sources and limits.
Process diagram only. It shows no observed opinion, geography, or result.

Observed versus modeled
A model earns trust by showing the miss.
Pheme publishes its committed validation set, source links, average error, and worst result. Direction can be useful while an exact percentage is still wrong. This is a simulation, not a poll.
