SUMMARY Data are presented showing that the subjects' basic reaction to situations where scaling of odor differences are concerned, is basically the same as far as their scale structure is concerned. The relative differences between scale‐point means are essentially the same. The major differences are the degrees to which they use the scale range, the location of the central value, and their discriminating ability in a few instances. Some scale positions are much more stable than are others. A study was made of paired‐comparison and intensity rating methodology, and it was concluded that intensity rating gave equally as much information as the paired comparison method in a shorter time.
