Generation Parameters (temperature · tokens · top-p)▸
Lower temperature = more consistent/literal analysis. Higher = more exploratory phrasing. Top-P at 0 uses the provider default.
If a provider blocks the call, try Anthropic, DeepSeek or OpenRouter.

Vrij (2008) · Individual Deviation Method
Absolute cues are unreliable across people. Comparing against this person's own baseline is the more defensible method.

Reverse-Thinking Interview Protocol
1
Open-ended start — let them narrate freely first
2
Reverse order — disrupts rehearsed scripts (RCI)
3
Withhold evidence — take the account before cross-checking (SUE)
4
Argue the opposite — ask them to reverse their own claim and watch coherence (Devil's-Advocate)
5
Unanticipated angles — spatial/sequence questions they can't pre-script
6
Baseline deviation — compare to Phase 00, not to absolutes
