The pros and cons are the points for and against a decision. Two columns on a sheet of paper.
The phrase is always plural and always in that order. It comes from Latin, where pro means for and contra means against, so the con here has nothing to do with a confidence trick. Weighing up the pros and cons is the standard way of describing a careful decision, and it is what a pros and cons list is for, which is one of the oldest pieces of practical advice there is.

Pros and cons are Latin fragments. Prō meant for or on behalf of, contrā meant against, and English kept the two halves of the argument without the sentences they belonged to.
