01 · Four distinct sentences
Observation: The meeting ended before anyone mentioned the missing item. Interpretation: Perhaps participants wished to avoid conflict. Social expectation: Members believe a public question would be received as disloyal. Consequence: Someone must act with less information. The first sentence is close to an observable fact; the others require further evidence.
02 · Three kinds of uncertainty
Uncertainty about events asks what happened. Uncertainty about motives asks why an actor behaved as they did. Uncertainty about norms asks what others do and expect. Verification can improve the first without fully answering the second or third.
03 · Three traps
Echo as corroboration: several retellings from one source are not independent reports. Silence as consensus: absence of dissent is not evidence of agreement. Clarity as compulsory exposure: making everything visible can destroy privacy and agency.
04 · Six responses; six trade-offs
Ask can open inquiry and add a burden. Verify takes time and sometimes fails to resolve what matters. Disclose can make a concern legible but expose someone. Pause can stop escalation while leaving ambiguity. Set a boundary can protect consent and produce informational partitions. Remain silent can preserve safety and preserve a harmful misunderstanding. There is no universal best button.
05 · Counterfactual climate
Replay the same choices under different starting expectations: preserve harmony, make uncertainty discussable, or defer to an agreed procedure. The simulation holds inputs constant so you can inspect path dependence inside a transparent fictional model. This is not evidence of how a real community will behave.
06 · One private exercise
Choose a fictional event and write four sentences: what could be observed, two competing interpretations, what social expectation may matter, and which person might bear uncertainty. Do not use the exercise to speculate about identifiable people, to disclose private information, or to conclude that someone owes you an explanation.
