Each sub-question captures a correlated failure mode (legal delay, peeling paint, algae recurrence, ongoing reporting of needed repairs) that all depend on the same troubled repair project; a weighted average reflects that any one recurring problem lowers the probability of a clean 'fully repaired' resolution.

## Question
Will the Lincoln Memorial Reflecting Pool be fully repaired before September 2026?
## Description / Resolution Criteria
## Description
The [Lincoln Memorial Reflecting Pool](https://en.wikipedia.org/wiki/Lincoln_Memorial_Reflecting_Pool) is a large, shallow rectangular pool on the National Mall, in Washington, D.C., located between the Lincoln Memorial and the Washington Monument.
In recent years, the pool has been plagued with algae. In April 2026, President Donald Trump announced that the pool would receive a new coating, in "American flag blue," using the ["latest and greatest filament."](https://www.cbsnews.com/news/trump-resurfacing-lincoln-memorial-reflecting-pool-blue/) Trump also estimated that the repair would take a week and cost about \$1.5 million.
On May 11, 2026, as work on the pool continued, [a lawsuit was filed](https://storage.courtlistener.com/recap/gov.uscourts.dcd.292242/gov.uscourts.dcd.292242.1.0.pdf) to halt the work, and it was revealed that the cost of the repairs had ballooned, to [\$13.1 million](https://www.nytimes.com/2026/05/11/us/politics/reflecting-pool-paint-contract-trump.html), set to be paid to a contractor that Trump had selected. Over \$1M more was paid to another contractor, for algae treatment.
The repairs were deemed completed on June 5, 2026, but within a week [algae was again observed](https://www.politico.com/news/2026/06/12/algae-resurfaces-in-reflecting-pool-multi-million-dollar-renovation-00960609) in the pool, which the administration declared was ["residual."](https://www.cnn.com/2026/06/10/politics/algae-reflecting-pool-trump) Within another week, observers noticed that the pool's new coat of paint was [already peeling](https://wtop.com/dc/2026/06/blue-paint-on-bottom-of-reflecting-pool-appears-to-be-peeling-away/), which the administration blamed on vandalism. [Several people](https://www.nbcnews.com/news/us-news/6-people-arrested-connection-alleged-vandalism-reflecting-pool-trump-s-rcna351409) have been arrested for allegedly damaging the pool, though some reporting has [cast doubt](https://www.nytimes.com/2026/06/23/us/trump-reflecting-pool-green-peeling.html) on the government's assertions.
On June 21, 2026, Trump announced that repairs to the pool would immediately [begin again](https://truthsocial.com/@realDonaldTrump/posts/116790016615762850), and one contractor estimated that the work would take a matter of [weeks](https://www.eenews.net/articles/reflecting-pool-repairs-will-take-weeks-contractor-says/). In the meantime, the lawsuit to halt work on the pool remains pending.
`{"format": "metac_reveal_and_close_in_period", "info": {"post_id": 44241, "question_id": 44250}}`
## Resolution Criteria
This question will resolve as **Yes** if, on September 1, 2026, the repairs to the Lincoln Memorial Reflecting Pool have been completed for at least one week and no credible sources are reporting that the pool is scheduled for or in need of further repairs.
## Fine Print
For purposes of this question, repairs include but are not necessarily limited to repainting or recoating the pool and the removal of algae from the pool.
***
This question's information (resolution criteria, fine print, background info, etc) is synced with an [original identical question](https://www.metaculus.com/questions/44241) which opened on 2026-06-30 17:00:00. This question will resolve based on the resolution criteria and fine print of the linked original question. However, if this question would resolve differently than the original question, then this question will be annulled. Additionally, if the original question's resolution could have been known before this question opened, then this question will be annulled.
## Sub-question decomposition
- (w=0.20) Will the pending lawsuit fail to halt or delay repair work through late August 2026? — An injunction or court delay would make completion by September 1 impossible.
- (w=0.35) Will the pool's paint/coating be intact (not peeling) and repairs deemed complete for at least one week by September 1, 2026? — The recurring peeling problem is the central obstacle to a clean, durable completion.
- (w=0.30) Will algae be absent/controlled in the pool such that no credible source reports it needs treatment by September 1, 2026? — Algae recurrence has repeatedly reopened the 'repairs needed' issue.
- (w=0.15) Will no credible sources report the pool as scheduled for or in need of further repairs as of September 1, 2026? — This directly captures the resolution's 'no further repairs needed' clause holistically.

## Cross-Market Signals
### No signal found
Information gaps:
- No court docket status after May hearing; unclear if injunction issued or ruling pending
- No confirmation of when second-round repairs actually completed or their status in July-August
- No data on whether algae was controlled after late June
- Base rate for how long comparable pool resurfacing/algae fixes take
Key uncertainties:
- Whether second repair round completed and held for a full week before Sept 1
- Whether algae recurs given water/design issues
- Whether lawsuit results in a work-halting injunction
- Whether new coating peels again
## 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.

"description": "## Description\nThe [Lincoln Memorial Reflecting Pool](https://en.wikipedia.org/wiki/Lincoln_Memorial_Reflecting_Pool) is a large, shallow rectangular pool on the National Mall, in Washington, D.C., located between the Lincoln Memorial and the Washington Monument.\n\nIn recent years, the pool has been plagued with algae. In April 2026, President Donald Trump announced that the pool would receive a new coating, in \"American flag blue,\" using the [\"latest and greatest filament.\"](https://www.cbsnews.com/news/trump-resurfacing-lincoln-memorial-reflecting-pool-blue/) Trump also estimated that the repair would take a week and cost about \\$1.5 million.\n\nOn May 11, 2026, as work on the pool continued, [a lawsuit was filed](https://storage.courtlistener.com/recap/gov.uscourts.dcd.292242/gov.uscourts.dcd.292242.1.0.pdf) to halt the work, and it was revealed that the cost of the repairs had ballooned, to [\\$13.1 million](https://www.nytimes.com/2026/05/11/us/politics/reflecting-pool-paint-contract-trump.html), set to be paid to a contractor that Trump had selected. Over \\$1M more was paid to another contractor, for algae treatment.\n\nThe repairs were deemed completed on June 5, 2026, but within a week [algae was again observed](https://www.politico.com/news/2026/06/12/algae-resurfaces-in-reflecting-pool-multi-million-dollar-renovation-00960609) in the pool, which the administration declared was [\"residual.\"](https://www.cnn.com/2026/06/10/politics/algae-reflecting-pool-trump) Within another week, observers noticed that the pool\u0027s new coat of paint was [already peeling](https://wtop.com/dc/2026/06/blue-paint-on-bottom-of-reflecting-pool-appears-to-be-peeling-away/), which the administration blamed on vandalism. [Several people](https://www.nbcnews.com/news/us-news/6-people-arrested-connection-alleged-vandalism-reflecting-pool-trump-s-rcna351409) have been arrested for allegedly damaging the pool, though some reporting has [cast doubt](https://www.nytimes.com/2026/06/23/us/trump-reflecting-pool-green-peeling.html) on the government\u0027s assertions.\n\nOn June 21, 2026, Trump announced that repairs to the pool would immediately [begin again](https://truthsocial.com/@realDonaldTrump/posts/116790016615762850), and one contractor estimated that the work would take a matter of [weeks](https://www.eenews.net/articles/reflecting-pool-repairs-will-take-weeks-contractor-says/). In the meantime, the lawsuit to halt work on the pool remains pending.\n\n`{\"format\": \"metac_reveal_and_close_in_period\", \"info\": {\"post_id\": 44241, \"question_id\": 44250}}`\n\n## Resolution Criteria\nThis question will resolve as **Yes** if, on September 1, 2026, the repairs to the Lincoln Memorial Reflecting Pool have been completed for at least one week and no credible sources are reporting that the pool is scheduled for or in need of further repairs.\n\n## Fine Print\nFor purposes of this question, repairs include but are not necessarily limited to repainting or recoating the pool and the removal of algae from the pool.\n\n***\nThis question\u0027s information (resolution criteria, fine print, background info, etc) is synced with an [original identical question](https://www.metaculus.com/questions/44241) which opened on 2026-06-30 17:00:00. This question will resolve based on the resolution criteria and fine print of the linked original question. However, if this question would resolve differently than the original question, then this question will be annulled. Additionally, if the original question\u0027s resolution could have been known before this question opened, then this question will be annulled.",
