How it's used
Originally a historical term referring to a state closing its borders to foreign trade, it is now frequently used metaphorically to describe individuals or organizations that are resistant to change. It carries a negative connotation of being stubborn, outdated, or unnecessarily insular. Unlike simply being shy, it implies an active, deliberate rejection of external influence or new ideas.
Examples
He is always closed-minded and refuses to listen to others' opinions.
If the company continues to be so isolated, it will be phased out sooner or later.
