Each correlated sub-question (dispute resolution, scheduling signals, bilateral stability, historical base rate) is estimated and blended via weighted average, with scheduling and dispute resolution carrying the most weight since they most directly determine whether a visit lands in the narrow July-August 2026 window.

Sub-questions (4)

sq1
Will China and South Korea resolve or set aside the diplomatic protocol dispute (over Taiwan status) that caused the postponement before September 1, 2026?
The stated cause of postponement; resolution is a prerequisite for a rescheduled visit in good conditions.
w=0.35
sq2
Will a Chinese Foreign Minister visit to South Korea be scheduled or announced for the July-August 2026 window?
A concrete scheduling signal strongly predicts the visit occurring within the narrow window.
w=0.35
sq3
Will overall China-South Korea diplomatic relations remain stable or improving (no new major rupture) through August 2026?
Broad bilateral momentum drives whether high-level visits proceed.
w=0.20
sq4
Historically, do postponed high-level Chinese FM visits to neighboring countries typically occur within roughly a year, in a given ~2-month window?
Base rate anchors the probability given the very narrow 2-month resolution window.
w=0.10

Rationale

(a) The resolution window is narrow — only July 1 to August 31, 2026 — leaving little room for a visit to land precisely there. (b) Status quo as of mid-2026: the Taiwan protocol dispute remains unresolved, no visit is scheduled, and China's Korean-peninsula attention is on North Korea (Xi's June 2026 Pyongyang state visit), so under status quo no visit occurs in the window. (c) NO scenario: dispute lingers, Beijing prioritizes Pyongyang, and any eventual Seoul visit gets tied to APEC (late 2026) rather than the July-August window. (d) YES scenario: a quiet diplomatic thaw sets aside the Taiwan protocol issue and Wang Yi makes a pre-APEC groundwork trip in the summer. Given absence of scheduling signals and the tight window, the probability is modest.

What would change my mind

A concrete announcement or leaked itinerary of a Wang Yi trip to Seoul in the summer 2026 window, or reporting that the Taiwan protocol dispute was formally set aside, would push me above 70%; confirmation the visit is deferred to APEC in late 2026 would push me below 30%.

Information gaps:
  - No direct reporting on whether the Taiwan protocol dispute was resolved
  - No scheduling signals for a July-August 2026 FM visit
  - Base rate: how quickly postponed Chinese FM visits typically reschedule
  - Status of APEC 2026 (South Korea hosting) which could drive a visit

Key uncertainties:

## Question
Will the Chinese Foreign Minister visit South Korea before September 1, 2026?

## Description / Resolution Criteria
## Description
China's Foreign Minister Wang Yi has recently planned to visit South Korea but [postponed](https://english.hani.co.kr/arti/english_edition/e_international/1255076.html) his visit due to a dispute of diplomatic protocol over the status of Taiwan.

`{"format": "bot_tournament_question", "info": {"hash_id": "793d9530ac6b4362", "sheet_id": "83"}}`

## Resolution Criteria
This question resolves as **Yes** if, after June 30, 2026 and before September 1, 2026, the Chinese Foreign Minister personally visits South Korea.

## Fine Print
"Personally visit" is defined as making contact, by foot or otherwise, with any surface on South Korea's internationally-recognized land territory.

## Sub-question decomposition
- (w=0.35) Will China and South Korea resolve or set aside the diplomatic protocol dispute (over Taiwan status) that caused the postponement before September 1, 2026?  — The stated cause of postponement; resolution is a prerequisite for a rescheduled visit in good conditions.
- (w=0.35) Will a Chinese Foreign Minister visit to South Korea be scheduled or announced for the July-August 2026 window?  — A concrete scheduling signal strongly predicts the visit occurring within the narrow window.
- (w=0.20) Will overall China-South Korea diplomatic relations remain stable or improving (no new major rupture) through August 2026?  — Broad bilateral momentum drives whether high-level visits proceed.
- (w=0.10) Historically, do postponed high-level Chinese FM visits to neighboring countries typically occur within roughly a year, in a given ~2-month window?  — Base rate anchors the probability given the very narrow 2-month resolution window.

Combination rule: **weighted_average**

## Required pre-forecast walkthrough

Before giving probabilities, walk through these explicitly:
  (a) The time left until the question resolves.
  (b) The status quo outcome — what happens if nothing changes from today.
  (c) A brief scenario that results in NO.
  (d) A brief scenario that results in YES.

## Calibration guidance

- **Estimate each sub-question in isolation.** Do not let your answer to one sub-question anchor your answer to another. This is the core of Fermi decomposition — independence forces more careful reasoning per factor.
- **Anchor on the status quo.** Require strong specific evidence to move far from it.
- 0.05 / 0.95 require strong, multi-source evidence. Avoid >0.97 or <0.03 unless the outcome is already settled or near-tautological — overconfident misses are punished heavily by the log score.
- **Anchor on prediction markets.** If liquid market prices (Polymarket / Kalshi) or a community forecast appear in the evidence, treat them as a strong, well-calibrated prior. Your final estimate should rarely sit more than ~15 percentage points from a liquid market on the SAME question — move further only with specific evidence the market lacks.
- **Treat research as fallible, not ground truth.** A single-source or "very recent" claim — especially one the evidence flags as unverified, possibly AI-generated, or low-credibility — must not drive you to near-certainty. When a load-bearing fact is unverified, keep at least 10-15% on the chance it is wrong.
- **Also provide a holistic estimate** — your overall gut feeling about the main question, BEFORE you see the mathematical combination. This serves as a sanity check: if the Fermi result and holistic estimate diverge wildly, something is wrong.
