Why Loneliness Can Exist in a Crowded World
Loneliness is a gap between the connection we have and the connection we want, which is why it can show up in a crowd. What research does and does not show.
Topic
Emotions & Relationships
How we connect, compare, trust, and feel alone.
Most of what matters to people arrives through other people: a friend who answers the phone, a rival whose success stings, a promise that was kept or broken. The articles here follow those connections and the feelings that ride along with them.
We separate what is measured from what is assumed. Loneliness, for example, is a feeling, while isolation is a count of contacts, and the two can diverge. Read these pieces for context, not diagnosis; they are educational and not a substitute for support from a qualified professional.

Words for this topic
- Attachment
- A lasting emotional bond, studied first in infants and caregivers by John Bowlby and Mary Ainsworth. Later research extended the idea to adult relationships, with ongoing debate over how stable styles are.
- Empathy
- The capacity to share in or understand another person's feelings. Researchers often separate emotional sharing from perspective-taking, since the two can come apart.
- Loneliness
- The distressing feeling that one's social connections are fewer or less satisfying than desired. It is a subjective experience, and it can occur even among people who are often around others.
- Need to belong
- The proposal, associated with Baumeister and Leary (1995), that humans have a strong drive to form and maintain lasting, positive social bonds. It is an influential theory rather than a settled law.
- Reciprocity
- The practice of responding to another's action with a similar one, such as returning a favor. Reciprocal exchange is a recurring feature of social life documented across many societies.
- Social comparison
- Evaluating our own abilities, opinions, or circumstances by measuring them against other people. The idea was formalized by Leon Festinger in 1954.
- Social isolation
- An objective lack of contact or few social relationships. It is distinct from loneliness: a person can be isolated without feeling lonely, or lonely while well connected.
- Trust
- A willingness to be vulnerable to another person or group based on positive expectations about their intentions or behavior. It can be built gradually and damaged quickly.
