Parochiality refers to a narrow or limited outlook, typically focused on one's own interests or locality. Synonyms for this word could include insularity, provincialism, or narrow-mindedness. Insularity describes a similar quality of being overly concerned with one's own community or group, often at the exclusion of others. Provincialism also suggests a lack of openness to outside ideas or perspectives, but specifically refers to a narrow-mindedness associated with rural or less developed areas. Narrow-mindedness emphasizes a lack of openness to new ideas, while also indicating inflexibility and unwillingness to consider other viewpoints. These synonyms all share a sense of closed-mindedness and a lack of broader perspective.
