Marriage and happiness

A good marriage is one of the life-factors most strongly and consistently associated with happiness.

Part of this apparent benefit comes from “reverse correlation”: Happiness causes marriage.

Happy people marry sooner and stay married longer than people with a lower happiness setpoint, both because they are more appealing as dating partners and because they are easier to live with as spouses.

But much of the apparent benefit is a real and lasting benefit of dependable companionship, which is a basic need; we never fully adapt either to it or to its absence.
