Claim

The fragmentation percentages apply to the study’s six open wetland classes in its 2018 European mapping extent, rather than to all wetlands globally.

Main unresolved issue: 2 counted evidence items have no independence review; repeats of one origin may be counted as several coverage:35d31145-d39d-89fa-97cb-5ca6389e5f2c

Not yet independently audited.Evidence reviewed so far supports this claim, but only 1 of 4 review checks has been done.

Why?

Strongest counted support: The Nature article specifies coverage across 38 European countries rather than a global wetland population. weight 1.800000 evidence

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 Supported to Supported.

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 0.50 → log-odds 0.000000 + 3.600000 (the counted weights) = 3.600000 → probability 0.9734

Under neighbouring settings of the same model: 0.9255 to 0.9908, a spread of 0.0653.

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.

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.
