Abstract: Probability representation has relied on binary probability or fuzzy extensions, yet such frameworks often fail to capture the suggested way humans evaluate partial belief. This paper introduces the Penta-State Probabilistic Model (PSPM), a five-valued probabilistic logic designed to model directional and biased probability. PSPM characterises probability with five understandable states: True, False, Partial-True, Partial-False, and Undecided. PSPM also provides a flexible, human-aligned representation of belief states, enabling more accurate system modelling for decision-making and neural-inspired reasoning.
