Grouping in the chemical senses

Abstract
Grouping of data into categories is a basic strategy to help understand the results of experiments in the chemical senses, as well as in the neurosciences in general. Thus, the categorizing process itself bears examination. It is argued that in some cases, rather than being inherent in the data, classifications simply reflect our human need to organize in order to understand. When the logic underlying classifications is emphasized, classifications can be of great scientific usefulness and importance.
