ROBIS 4-Domain Audit¶

Domain 1: Eligibility Criteria¶

Rating: Low risk

Criterion	Assessment
Criteria defined before searching	Yes — looked for the specific KPMG/Melbourne study cited
Criteria applied consistently	Yes — evaluated press materials against claimed statistics

Notes: Eligibility was straightforward since the claim names a specific source.

Domain 2: Search Comprehensiveness¶

Rating: Low risk

Criterion	Assessment
Multiple search strategies used	Yes — searched for study name, specific statistics, and author names
Searches designed to test each hypothesis	Yes — searched for contradictory figures and alternative studies
All results dispositioned	Yes
Source diversity achieved	Limited — single study means limited source diversity is expected

Notes: The claim references a specific named study, so search comprehensiveness is measured by ability to locate and verify that study rather than by breadth of sources.

Domain 3: Evaluation Consistency¶

Rating: Low risk

Criterion	Assessment
All sources scored using same framework	Yes
Evidence typed consistently	Yes
ACH matrix applied	Yes
Diagnosticity analysis performed	Yes

Notes: Consistent evaluation framework applied.

Domain 4: Synthesis Fairness¶

Rating: Low risk

Criterion	Assessment
All hypotheses given fair hearing	Yes — H1 not dismissed despite press materials showing slight differences
Contradictory evidence surfaced	Yes — noted discrepancies in precise figures
Confidence calibrated to evidence	Yes — rated Very likely rather than Almost certain due to unresolved precision questions
Gaps acknowledged	Yes — noted need for full report PDF

Notes: The assessment fairly represents the minor discrepancies without overstating them.

Overall Assessment¶

Overall risk of bias: Low risk

The claim references a specific, verifiable study. The evidence strongly confirms the core claim with minor precision questions that are likely explained by the difference between press summary rounding and full report precision.

Researcher Bias Check¶

Confirmation bias risk: Low. The claim is a factual attribution to a named study, limiting interpretation latitude.
No researcher profile provided: Cannot assess declared biases.
