“Fallacy” refers to a false or mistaken belief, often one that is based on faulty reasoning.

Fallacies can be hard to detect because they often seem reasonable at first glance.
“Mistakenness” emphasizes being in error or having made a wrong judgment. For instance, “There was a certain mistakenness in his assumption.” It suggests a sense of personal responsibility for the error, as if one has misjudged or misinterpreted something.
“Incorrectness” is a more straightforward term that simply means not being right or accurate. For example, “The answer was marked as incorrect due to its incorrectness.” It focuses on the lack of correctness without necessarily specifying the nature or cause of the error.
In conclusion, these synonyms for “erroneousness” all describe different aspects of being wrong. Whether it’s a fallacy in reasoning, a sense of mistakenness, or a general incorrectness, they all convey the idea of something being not as it should be.
