Four Days on the Ridge
Would you take the truce when the odds change?
Risk, framing & ceasefire verification · 60–75 min
Learning goals
- Identify a change in reference point while the possible outcomes and odds stay fixed.
- Calculate expected posts and explain why two choices with the same average may carry different risks.
- Compare what the July 4 statement and July 11–12 accounts establish about the Kaksar withdrawal.
- Revise advice using a changed forecast and a field signal, then apply verification reasoning to Korea.

Course materials
Before the activity
Briefings, probability tools, maps, and source excerpts are in the game. No advance reading is required.
Syllabus description
Advise a cabinet weighing a local truce. Compare how two briefings frame the same odds, investigate reports from Kargil, and decide what would count as evidence that a handover took place. Students produce a cabinet report with decisions, calculations, document comparisons, and nine written responses.
Discussion prompts
- What decision changed with the reference point? What else might explain the difference?
- When is a guaranteed four more attractive than a gamble that averages four? Whose losses do the post totals leave out?
- What would you want to see on July 12 to tell that a position was empty and that its control had changed?
What to assess
Read the calculations alongside the nine explanations. Look for an explicit reference point, careful source attribution, and advice that follows from the odds and the field signal.
Limitations
The briefings, four-day truce, point values, and probabilities are teaching models. The case materials separately identify the dated Kargil and Korea records.
