Social isolation
Updated November 9, 2026
Social isolation is having few relationships or little regular contact with other people, measured by the contact itself rather than by how you feel about it.
Social isolation describes your circumstances: how often you see or talk to people and how many people you have around you. It overlaps with loneliness but isn't the same thing. Someone can live alone and see few people without feeling lonely, and someone surrounded by people can still feel lonely.
The distinction matters when you think about an AI companion. An AI can add conversation to a quiet day, but talking to an AI isn't contact with people. It fits best next to calls, visits and shared plans.
