Pioneered by Charles Osgood in 1952, semantic differential scales are a popular technique for measuring people’s attitudes toward nearly anything. Semantic differential scales use a standardized set of bipolar adjectives (see Figure 1) on which research participants rate an issue or object. This simple procedure confers a variety of benefits, both for researchers and study participants.
Through a series of statistical analyses, Osgood identified three recurring, stable dimensions on which people can judge nearly anything (see Table 1): (a) evaluative, focused on the value of the object (e.g., good/bad); (2) potency or power of an object (e.g., strong/weak); and (3) activity or movement of an object (e.g., slow/fast).
