When someone states something as fact that they wish was true though all actual FACTS show it is NOT. Being wishinformed is typically from people who do not understand citing sources.
Wishinformation is data that is presented presented as fact when it is not supported by any real evidence; just what someone wishes was true. It is used in presenting an argument that has no merit but is based on an opinion as opposed to actual evidence that supports it. Someone who believes this false statement has been wishinformed, they believe because they want to.
I thought he was a normal guy until he started in with wishinformation on the earth being flat.
She used a bunch of silly wishinformation to support her point and could not provide a single, provable fact. SMH
