THE PERSON BEHIND THE DEMOGRAPHICS
Aaron Brown, 84. Retired. Renting and living alone after divorce.
From Aaron’s existing Synthros profile and stored context · Explore the individual behind the response
CIVIC TWINS · COGNITIVE ARCHITECTURE
Each juror brings identity, beliefs, bias, emotion, social context, and a memory that develops through the case.
Life circumstances, information habits, and available local context shape the starting point.
The private cognitive component produces a simulated reflection summary; the juror gives an initial view.
Recent case memory and the panel’s initial responses inform the next response.
A case-memory summary records the final view and what changed. Follow-ups use the saved case context.
Identity · Private cognition · Recent memory · Long-term memory · Emotion · Stress · Goals · Social dynamics · Beliefs · Biases · Communication · Decisions · Reflection
Four connected cognitive components · Case-specific memory · Captured context and timestamps
ONE FICTIONAL CASE
THE APPROVED RECORD
Two vehicles collide at an intersection.
Both drivers say the light was green.
The camera image does not show the signal.
Research question
What evidence does this presentation leave unresolved?
ACTUAL MODEL RESPONSE · FICTIONAL TEST
“Still stuck on the missing signal in the camera image [S1]. Both drivers say they had the green, but we have no way to verify that.”
Aaron Brown Excerpt from his final response
What establishes the signal’s state at the time of the collision?
Excerpt from a twelve-juror cognitive test. Other responses in that run had vote/reason conflicts, which were flagged for review. This example is not a verdict prediction.
FOLLOW-UPS & CONTROLLED COMPARISONS
FOLLOW THE QUESTION
Ask the juror to elaborate on the recorded response. Explore the assumption, source, or unanswered question behind it.
Example follow-up prompt · No fabricated answer shown
CHANGE THE PRESENTATION
Run the variation with the same panel and seed. Compare the reactions, questions, and source references.
Hypothetical variation · A result has not been claimed
Did the new material address the uncertainty—or reveal another one?
Comparisons preserve the panel and captured context; they stop if the checked model versions have changed. Inference can still vary.
