Quality vs. Quantity of Relationships
A few close, dependable relationships often matter more for well-being than a large number of contacts.
Beta content. Evidence for this dimension is still developing; grade is conservative and will be upgraded as more research is reviewed.

Evidence suggests…
Evidence suggests both the structure of a network (how many, how often) and its quality (how supportive, how close) independently relate to health, and that felt quality/loneliness often carries stronger associations than raw counts. This is graded B: the quality-over-quantity claim is well supported directionally but effect comparisons vary by study and measure.

Common misconceptions
- Myth: more friends is always better. Reality: a small number of trusted ties can be enough.
- Myth: you must choose quality or quantity. Reality: both dimensions contribute independently.
What we won't claim
- Do not prescribe an optimal number of friends for any individual
- Do not imply large networks are inherently unhealthy
When to seek a professional
- Persistent loneliness or isolation accompanied by low mood, hopelessness, loss of interest, or withdrawal lasting 2+ weeks → encourage contact with a primary care provider or mental health professional
- Thoughts of self-harm or that life is not worth living → direct to crisis line / emergency services immediately
