overnarrowing

Overnarrowing is the term used to describe an excessive restriction of options, categories, or scope in a process, guideline, description, or system. It occurs when a boundary or criterion becomes too tight, excluding legitimate cases or possibilities that should reasonably be included. The concept is applicable across disciplines and often carries implications for accuracy, fairness, and flexibility.

In medicine, overnarrowing can refer to pathological narrowing of bodily passages or channels, such as blood vessels, airways, or ducts, where the narrowing impedes normal function. It can result from disease, scarring, or inflammatory processes and may require diagnostic assessment to determine appropriate management. The medical sense is typically contrasted with a healthy or appropriate degree of openness in physiological conduits.

In linguistics and semantics, overnarrowing describes a situation where a word or label is applied too restrictively, excluding items that should be encompassed by the term. This can hinder accurate communication and lead to misclassification, especially in language development and the evolution of word meanings.

In policy, governance, and organizational design, overnarrowing occurs when criteria, standards, or eligibility rules are drafted too narrowly. This can limit participation, reduce adaptability to new circumstances, and stifle innovation, sometimes increasing inequity or inefficiency.

In data science and knowledge organization, overnarrowing in taxonomies or labeling schemas can harm generalization and interoperability, causing models to perform poorly on unseen or borderline cases.

Mitigation involves periodic review of boundaries, incorporating input from diverse stakeholders, and balancing precision with inclusivity to preserve usefulness without sacrificing accuracy.
