Seven cognitive layers, calibrated against longitudinal data and behavioral science literature. Not a profile — an architecture.
Name, age, family composition, occupation, region. The stable foundation on which the witness is built — calibrated against IBGE / PNAD strata. Identity is sticky: the synthetic person doesn't become someone else between sessions.
What happened to this person. First job, first child, first credit denial, first move. Events with dates, held on record, available to later reasoning.
Affective states that modulate decision — loss aversion, financial anxiety, pride of belonging. Not noise: variables that change how the same person responds to the same stimulus at different moments.
What a person says in a group is not what they think alone. We model the gap between declared and private behavior — the gap that destroys focus groups.
Religion, affiliation, cultural norms, moral boundaries. What is simply off the table for this person — and what no discount will move.
How this person decides — heuristics in use, cognitive load, susceptibility to social proof, anchoring, loss aversion. Drawn from the behavioral science corpus, not invented.
The person remembers across sessions. What they said in March, what they bought in June, what they changed their mind about in November. Longitudinal coherence is the layer that separates an observatory from a survey panel.

Each of these instruments didn't predict the future — they gave more eyes to those who needed to observe. That is the lineage we place ourselves in.
