Is disbelief in an idea the same as believing that the idea isn’t true? No: mere disbelief in the truth of a proposition is not equivalent to the belief that the proposition is false and that the opposite is true. If you make a claim and I disbelieve it, I am not necessarily saying that your claim is false. I may not understand it well enough to say one way or the other. I may lack enough information to test your claim. I may simply not care enough to think about it. There are a variety of reasons why I might disbelieve something and the most basic meaning for disbelief is to simply lack belief.”
