That which is easily done is soon believed.

An account of an action can seem credible simply because the action would have been easy to carry out. Its feasibility makes the report quick to accept.

The proverb points to a weakness in that judgment: knowing that someone could easily have done something does not establish that they did it.

Use this proverb when someone accepts a claim that an action occurred mainly because it would have been simple to carry out, especially when ease is being treated as evidence.
