Rejecting global incongruence can establish agreement among some distance matrices without showing that all modalities share the same structure.
Principle And Provenance
Legendre and Lapointe (2004), PDF2–6 and13, define the CADM alternative as congruence of at least some matrices. Their historical whisky example is an illustration, not a new blinded tasting experiment.

Application
Keep sensory modalities distinct in the Lab. A later research analysis needs corresponding objects, defensible distance measures, object-label permutations, appropriate follow-ups and multiplicity handling. Small p values do not demonstrate large associations or prediction accuracy. A nonsignificant finish comparison does not prove independence. No access
