Narrowness refers to the quality of being limited in width or extent. It can describe physical objects, such as a narrow road or a narrow doorway, which restrict movement or passage. In a broader sense, narrowness can also apply to ideas or perspectives, indicating a lack of openness or flexibility in thinking. In psychology, narrowness can relate to cognitive biases, where individuals may focus on a limited set of information or viewpoints. This can hinder problem-solving and creativity, as seen in situations where people are unwilling to consider alternative solutions or perspectives, leading to a more constrained understanding of issues.
