Informing Science Institute
Knowledge of a statement exists when the statement is true, it is believed, and it is justified. While there are somewhat unusual situations where the justified, true, belief model does not produce what some consider being knowledge, this definition of knowledge serves as an adequate model for most purposes. Information being produced by processes is examined, and then expanded to show how different kinds of information combine to produce knowledge. Qualitative and quantitative definitions and variants of truth, justification, and belief are proposed, providing an informing based model of knowledge that can be applied to a range from individual statements to larger groups and societies.
