Systems and methods are provided for graphically representing uncertainty in an assisted decision-making application. A database contains a class vector for each of a plurality of objects of interest. A given class vector includes a plurality of possible classes for its associated object of interest and a corresponding set of confidence values. The database also contains a set of assumptions associated with each confidence value. A user interface displays a plurality of graphics representing the objects of interest. A given graphic includes a set of at least two class icons, each corresponding to one of the plurality of classes associated with its corresponding object of interest. The graphic also includes a qualitative indication of the confidence values associated with the set of classes. The assumptions associated with a given confidence value are retrievable by a user by selecting the class icon associated with the confidence value.
