FTA: Lying is when you say something that you know to be false. Bullshitting is when you say something that you don’t know is true or not. There is a spectrum here also, where people may be exaggerating or stretching what they know to be true, mixing in speculation and opinion with facts, distorting what is known with a conscious or unconscious agenda (motivated reasoning), or they are simply gullible themselves. How carefully do you vet a specific piece of information before you accept it and repeat it as true, and how transparent are you about your sources and your confidence in the information?

Most people, I would argue, are not careful enough. Being skeptical is essentially about being really careful and transparent about the information you accept.
