Understanding friendships, your own included

The difficulty is real and measurable. It stems not from a personal disposition but from the disappearance of one precise kind of situation.

Confiding is the criterion defining the narrowest circle in most measurement instruments. What it produces has been studied mainly in the laboratory.

The result is old, robust, and it still surprises. It stems less from a misunderstanding than from what the word covers.

The literature on repairing relationships is almost entirely marital or workplace-based. What exists on friendship amounts to few studies.

Contact frequency predicts the duration of a relationship poorly. Available work points to properties less easy to count.

Counting help actually received and asking whether someone feels supported give divergent results. The paradox has an explanation.

They rarely stop by decision. The accounts collected most often describe a gradual halt nobody ever put into words.

The workplace is the leading supplier of relationships in adulthood. It is also the context whose relationships survive departure least well.

A Dutch study followed the same people for two decades. Its main result contradicts the intuition of a stable circle of friends.

A 1997 experiment produced a widely reused procedure. What it establishes is narrower, and more interesting, than its coverage suggests.

A 2019 study proposed precise hourly thresholds, widely taken up. Its method invites reading those figures as an order of magnitude, not a measurement.

A 1950 study of student housing showed that distance in metres predicted friendships. The result has been confirmed and refined since.
