Doty reviewed the long history of classifying odors and linking them to chemistry. His conclusion: odor qualities are cognitive constructs. They don't map neatly onto physical dimensions the way color maps to wavelength, and computational models “haven’t fared well.” doi.org/10.1093/chemse/bjaf022
Abstract. Attempts to map odor percepts to physical and chemical parameters have a long and challenging history. In contrast to color vision, where three c
