Assessment

Leans supported

Score: 0.6987 under ledger-default@0.3.0 at snapshot 27745

3 of 4 review checks done · 1 counted · 2 by the author only

2 independent evidence lineages · review checks 1 of 4 · stability LOW

Main unresolved issue: 4 counted evidence items have no independence review; repeats of one origin may be counted as several coverage:32cf21da-7626-84f1-9680-733664a8a3e6

Not yet independently audited.Evidence points both ways.This assessment depends heavily on modeling choices.Every quoted passage was confirmed on the page when Galedra fetched it.

Why?

Strongest counted support: The abstract directly reports stronger compensatory responses under warmer temperatures and higher species diversity in grassland frost experiments. weight 2.000000 evidence

Strongest counted contradiction: An independent grassland experiment found opposite spring and autumn frost effects, including reduced richness and negative productivity effects after autumn frost. weight 0.540000 evidence

Suppressed as dependent: The passage directly reports that warmer temperatures and higher species diversity strengthen compensatory responses in grassland frost experiments.

Review gaps: qualifiers reviewed, opposing search done, independence reviewed

What would most change this: One independent, direct measurement that contradicts this claim would move it from Leans supported to Leans contradicted.

How the number was reached

Each counted link is weighed by multiplying the factors the model declares; a factor it does not declare is not shown. Every factor name below links to what that number means.

prior 0.35 → log-odds -0.619039 + 1.460000 (the counted weights) = 0.840961 → probability 0.6987

Under neighbouring settings of the same model: 0.5994 to 0.7823, a spread of 0.1829.

Half-even rounding, six places for weights and four for the probability. The same inputs under the same model reproduce this exactly; that is what the trace hash above is for. How a score is worked out explains every factor, why it is there, and what the model sets it to.

Evidence against

An independent grassland experiment found opposite spring and autumn frost effects, including reduced richness and negative productivity effects after autumn frost.

Shows that frost season and community response can reverse the direction, limiting an unqualified generalization.

Qualifications

The grassland experiment concerns late-spring frost, not frost events in general.

From Overcompensation of vegetation productivity after late-spring frost in the Northern Hemisphere Read 2026-09-29 Relevance DIRECT Steps 0 Counted

The claim should be read as applying to the study’s late-spring-frost grassland experiments.

Inferences

Concluded from

None.

Used as a premise in

None.

An inference is interpretation, not evidence: it never changes the assessment of its conclusion. Each premise is a claim with its own evidence.

Threads

None. Threads are for disagreements about how a determination was made — a statement whose figures are not in the passage it rests on, two sources that may share an origin. Something about the world belongs in the evidence above.

Claim edges

None. Edges are stored and displayed; v0.1 does not propagate probability across them.

Summary

Leans supported. The main support is: The abstract directly reports stronger compensatory responses under warmer temperatures and higher species diversity in grassland frost experiments. 21c975bb

Against that, contradiction: An independent grassland experiment found opposite spring and autumn frost effects, including reduced richness and negative productivity effects after autumn frost. 97a3c5bf

1 further item repeats the same origin and is not independent evidence. 8f8ed90a

Qualifier: The grassland experiment concerns late-spring frost, not frost events in general. afd040a3

A search for evidence in the opposing direction found something; see the counted evidence. 1a68ac9f
