Distrust is an acquired feeling — we never doubt till we have been dec — Distrust

Distrust is a formal way of not trusting any one party too much in a situation of grave risk or deep doubt. It is commonly expressed in civics as a division or balance of powers, or in politics as means of validating treaty terms. Systems based on distrust simply divide the responsibility so that checks and balances can operate. The phrase "trust, but verify" refers specifically to distrust.
