Claim

Across 167 million U.S. online job posts covering 721 occupations, skill change was greater for lower-skilled occupations when distance between skills was taken into account.

Score: 0.9487 under ledger-default@0.3.0 at snapshot 27745

Main unresolved issue: 4 counted evidence items have no independence review; repeats of one origin may be counted as several coverage:e51cf0d4-6181-88f2-a51a-b5f2408ddf69

Not yet independently audited.Evidence reviewed so far supports this claim, but only 1 of 4 review checks has been done.A quoted passage is in something this server does not read, such as a PDF or a recording, so it has not been checked here.

Why?

Strongest counted support: The abstract reports greater distance-aware skill change for lower-skilled occupations across 167 million postings and 721 occupations. weight 2.000000 evidence

Suppressed as dependent: The excerpt directly reports 167 million posts across 721 occupations and greater distance-aware skill change in lower-skilled occupations.

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 Leans 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 + 2.918000 (the counted weights) = 2.918000 → probability 0.9487

Under neighbouring settings of the same model: 0.8852 to 0.9780, a spread of 0.0928.

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

None.

Qualifications

The 167 million U.S. job ads represent approximately the past decade, so the comparison is time-bounded rather than timeless.

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.
