best interests

Someone's optimal outcome

Best interests refers to what most benefits or serves someone's welfare, especially when that person cannot decide for themselves.

The phrase dominates legal and medical contexts: courts determine a child's best interests in custody disputes; doctors act in a patient's best interests when the patient is incapacitated.

It's in your best interests to cooperate.

The plural "interests" is fixed—"best interest" sounds off to most ears.
