They seem incapable of thinking beyond their own interests...
"The behavior you are describing is generally referred to as egocentrism or a lack of empathy.
Egocentrism is a cognitive bias where a person is unable to understand or consider that other people may have a different perspective, opinions, or feelings than their own.
While common in childhood development, some adults retain this self-focused mindset and struggle to imagine a viewpoint other than their own.
A lack of empathy is the inability to understand or share the feelings of another person. This can be a trait in various personality types or conditions.
The inability to think beyond one's own interests can also be associated with:
Narcissism: This personality trait involves a constant need for admiration and an excessive focus on oneself, often stemming from a need to feel important and valued.
Cognitive Bias: People may exhibit biases, such as the false consensus effect (overestimating how much others share their perspective) or the Dunning-Kruger effect (overestimating their own competence due to a lack of knowledge in a specific area).
Personality Disorders: Certain personality disorders, such as schizoid personality disorder or aspects of Borderline Personality Disorder, can involve being absorbed in one's own thinking or difficulty maintaining stable relationships due to a limited perception of others.
Lack of Theory of Mind: This is the ability to recognize that other people's experiences and thoughts are separate from one's own.
Most people develop this skill in childhood, but some do not.
If you are dealing with someone who exhibits this behavior, it can be emotionally challenging, and you may need to set boundaries or seek support for yourself."
