One-dimensionality refers to a lack of depth or complexity in a person, idea, or situation. Synonyms for one-dimensionality include shallowness, simplicity, flatness, superficiality, and narrow-mindedness. These terms suggest a limited perspective, a lack of consideration for alternative viewpoints, or an inability to see beyond the immediate surface. One-dimensional characters in literature or film, for example, are often criticized for lacking believability or nuance, while arguments that rely on one-dimensional thinking might be dismissed for failing to consider multiple angles or factors. By recognizing and avoiding one-dimensionality, individuals can strive to develop a more complete understanding and appreciation of the world around them.
