What term describes the lack of exposure to new ideas or practices of specific groups?

The term that describes the lack of exposure to new ideas or practices of specific groups is indeed isolation. This concept refers to a situation where individuals or groups are separated from broader social, cultural, or intellectual interactions, leading to limited exposure to diverse perspectives and practices. This isolation can occur within communities, resulting in a narrow worldview and a lack of innovation or creativity due to the absence of external influences.

When individuals or groups are isolated, they may also miss opportunities for growth, learning, and adaptation to new trends or changes in their environment. This can hinder personal, social, or professional development, reinforcing existing beliefs and practices without challenge or innovation. In contrast to the other terms, which may relate to different social dynamics, isolation specifically highlights the disconnect from a wider array of ideas and experiences.
