Abstract:
Doty (Odors as cognitive constructs: history of odor classification and attempts to map odor percepts to physical and chemical parameters. 2025. Chem Senses 50:bjaf022) provides a thorough historical review of odor classification but underestimates recent advances in quantifying odor space. He argues that odor qualities are cognitive constructs that do not map well to physicochemical properties. While odor is indeed cognitively mediated, practical and predictive rules for olfaction exist and continue to improve. Therefore, we suggest that Doty's historical review should be read not as a eulogy for physicochemical modeling, but as a historical baseline that the field is now surpassing.
