self-centeredness

This term carries a strong negative connotation, describing a personality trait where an individual lacks empathy or consideration for others. It suggests a psychological blindness to the needs of those around them, often resulting in social friction or isolation. While similar to narcissism, it focuses more on the habitual preoccupation with one's own perspective rather than a clinical need for admiration.

As an abstract noun ending in the suffix -ness, this word is strictly uncountable. It describes a quality or state of being rather than a discrete object. Consequently, it cannot be pluralized and does not take an indefinite article like a or an; instead, it is used with quantifiers such as some, much, or a great deal of.
