Indicators and Signposts¶

Why It Matters¶

Hypotheses and scenarios are useless if you can't detect which is occurring in real-time. Indicators transform abstract analysis into concrete monitoring. They prevent holding onto wrong judgments too long (if you see disconfirming indicators, you must revise) and enable early detection of change (leading indicators provide advance warning).

The Key Move¶

For each hypothesis or scenario, ask: "What would I observe if this is happening? What would be present if this is true and absent if false?" Be specific - not "increased tension" but "Russian troop movements to border exceeding X battalions." Distinguish diagnostic indicators (strongly associated with one hypothesis) from general indicators (could indicate multiple hypotheses). Monitor systematically - indicators only work if you actually watch for them.

Classic Application¶

Cold War monitoring of Soviet nuclear testing. U.S. intelligence didn't wait to detect actual tests - they identified indicators: "Unusual seismic activity in known test sites," "Evacuation of nearby populations," "Communications pattern changes at test facilities," "Meteorological observation aircraft deployment." When multiple indicators appeared, they predicted tests before they occurred, enabling diplomatic responses.

Surprising Application¶

Relationship health monitoring. Rather than vague "things seem off," identify specific indicators: "We haven't had a substantive conversation in three days," "Plans are made separately not jointly," "Conflicts are avoided rather than addressed." When multiple indicators appear, it signals relationship drift requiring attention. Makes the abstract ("relationship quality") concrete and actionable.

Failure Modes¶

Identifying indicators but not monitoring them (they require systematic observation). Making indicators too vague to detect reliably ("increased activity" vs. "three or more flights per day"). Not specifying thresholds (how much of X constitutes an indicator?). Ignoring that indicators can be manipulated by adversaries (if they know what you're watching for). Treating indicators as proof rather than signals requiring investigation (they increase probability but don't confirm).
