  To a certain extent, it may seem that there are just three doxastic attitudes to adopt regarding the truth of a claim: believe it’s true, believe it’s false (i.e., disbelieve it), and suspend judgment on it. In the most straightforward sense, two individuals disagree about a proposition when they adopt different doxastic attitudes toward the same proposition (i.e., one believes it and one disbelieves it, or one believes it and one suspends judgment). But of course there are levels of confidence one can have regarding a proposition as well. We may agree that global warming is occurring but you may be much more confident than I am. It can be useful to use ‘disagreement’ to cover any difference in levels of confidence: if \(X\) has one level of confidence regarding belief \(B\)’s truth while \(Y\) has a different level of confidence, then they “disagree” about \(B\)—even if this is a slightly artificial sense of ‘disagree’. These levels of confidence, or degrees of belief, are often represented as point values on a 0–1 scale (inclusive), with larger values indicating greater degrees of confidence that the proposition is true. Even if somewhat artificial, such representations allow for more precision in discussing cases.
