Definitionv1DF-283
Anomaly
a specific instance where reality contradicts an expectation generated by a mental schema, which becomes significant when it clusters with other similar instances, signaling that the underlying schema requires revision
Why This Is a Definition
This definition precisely establishes the semantic boundary of 'anomaly' by identifying its genus (a contradiction between expectation and reality) and differentia (specificity, schema generation, and clustering significance). It distinguishes anomalies from mere exceptions by requiring the clustering pattern that signals schema revision needs, making it a precise definition for the curriculum's use of the term.
