Independent Demonstration Project — Not Client Work

International Politics Benchmark

A political-history question where the widely quoted date is not the answer.

Treaties have at least two dates — the day they are signed and the day they take effect — and popular accounts collapse them into one. This benchmark asks for the second, which is recorded in a formal depositary entry and can also be derived from a published interval.

Project Overview

Frontier AI browsing systems can answer many questions by locating obvious keywords or matching information from highly ranked webpages. This project explores how to construct a research question that cannot be solved through a single search. The answer must remain short, stable and objectively verifiable, while the clues require the researcher to connect different people, dates, places, organisations, publications, events, records and quantities.

Research Goal

Design one difficult but fair browsing challenge.

Required Answer

A short, stable and objectively verifiable fact.

Evidence Standard

Every clue must be independently supported by reliable evidence.

Final Deliverable

A question, answer, clue set, source trail, validation log and JSON record.

Research question
A founding instrument agreed at a Californian conference that closed on 26 June 1945 only took effect once five named powers and a majority of the other signatories had ratified it. On what date did it enter into force?
Correct answer
24 October 1945
Answer-normalisation rules
Case-insensitive; punctuation ignored. Accepted variations: 24 October 1945; October 24, 1945; 24/10/1945; 1945-10-24.

Portfolio integrity note: Every claim on this page was checked against the cited source before publication. No source, quotation, locator or search result is invented; where a detail could not be verified directly it is described rather than quoted.

Research Method

  1. Step 1Establish the Answer

    Begin with a stable fact that can be confirmed through a reliable primary or authoritative source. Record the exact wording, document title, issuing organisation and publication date.

  2. Step 2Build Independent Clues

    Develop clues involving different fact types, including dates, people, places, organisations, works, events, records and quantities. Each clue must be independently checkable.

  3. Step 3Test Discoverability

    Run obvious, broad and targeted search queries. Record the results to identify accidental shortcuts, direct answer leakage and misleading pages.

  4. Step 4Construct the Evidence Chain

    Explain how each source supports a specific clue and how the clues logically combine to identify one answer.

  5. Step 5Validate and Package

    Recheck every source, confirm answer uniqueness, document limitations and export the completed benchmark record in a consistent JSON format.

Clue Matrix

Each clue constrains the answer from a different direction. No single row is sufficient on its own, and every row can be checked against a source another researcher can reach.

Verified clue set

Statuses are editable so the matrix can be worked through row by row. Scroll sideways on small screens.

AI-generated statements are never treated as evidence. Every factual claim must be verified against an accessible external source.

Project Outcome

This benchmark is complete: the answer is fixed, 3 evidence records are attached to specific clues, and 4 validation searches are documented, including those that exposed the answer. It demonstrates the ability to approach an unfamiliar subject systematically, separate evidence from assumption and document research so that another person can audit it.

Reflection and Limitations

What made the question difficult

Two dates compete and the more famous one — 26 June 1945 — is given in the question itself as a clue, so a careless solver simply repeats it.

Which searches failed

Queries phrased around the signing returned the decoy date only. The effective date surfaces reliably only when ratification is named.

Which source proved decisive

The depositary treaty record, because it states the effective date as a formal field tied to a specific article rather than as narrative text.

How ambiguity was removed

Naming the ratification condition rules out every other 1945 milestone, including the opening of the first General Assembly in 1946.

What an AI browsing agent might get wrong

Answering 26 June 1945, or giving 10 January 1946 by confusing entry into force with the first session.

Remaining limitations

The effective date is well indexed, so a direct query still resolves it; the difficulty comes from the wording of the question rather than from search depth.

Recommended future improvements

Require the number of ratifications deposited by that date, which is only reachable from the depositary tables.

Need a careful researcher for complex web investigations?
