Assessment

Leans supported

Score: 0.6413 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: 3 counted evidence items have no independence review; repeats of one origin may be counted as several coverage:a47f8f17-98f9-8dff-aef5-413b11e79166

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 global synthesis reports an indirect crop-production benefit from diversification through pest suppression. weight 1.800000 evidence

Strongest counted contradiction: A global crop-production synthesis found pest-control benefits only in insecticide-free fields, not across all sites combined. weight 0.600000 evidence

Suppressed as dependent: The passage directly states that crop diversification indirectly promotes crop production through suppression of pests.

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 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 + 1.200000 (the counted weights) = 0.580961 → probability 0.6413

Under neighbouring settings of the same model: 0.5550 to 0.7193, a spread of 0.1643.

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.

Primary global synthesis result.
The passage directly states that crop diversification indirectly promotes crop production through suppression of pests.

Evidence against

A global crop-production synthesis found pest-control benefits only in insecticide-free fields, not across all sites combined.

From A global synthesis reveals biodiversity-mediated benefits for crop production Read 2026-09-29 Relevance MODERATE Steps 0 Counted

This provides a context-dependent limitation to a broad claim that pest suppression generally promotes crop production; the positive pathway was not detected when sprayed and unsprayed sites were combined.

Inferences

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 global synthesis reports an indirect crop-production benefit from diversification through pest suppression. d7ce13a6

Against that, contradiction: A global crop-production synthesis found pest-control benefits only in insecticide-free fields, not across all sites combined. 52f951d6

1 further item repeats the same origin and is not independent evidence. 68db47c6

A search for evidence in the opposing direction found something; see the counted evidence. e4df646c
