Abstract:

Marketing materials often create difficulties for consumers through elements like unconventional fonts or distracting background images, leading to perceptual disfluency—a sense of difficulty encoding information. During choices, consumers can mistake perceptual disfluency for choice difficulty, a feeling of indecision. Building on this idea, eleven preregistered experiments (N = 9,042) show that, when making choices, perceptual disfluency can lead consumers to rely on information that feels more intuitively appealing to them, such as a familiar brand, a preferred country of origin, or a recommendation, rather than on information they must carefully consider like numerical product specifications. Differing from the effect of perceptual disfluency in other situations, during choices, this effect occurs because consumers process information less deeply, engaging in relatively more intuitive and less analytical processing. This effect is amplified when consumers endorse a “fast-is-accurate” lay theory. In contrast, it does not occur when consumers do not mistake perceptual disfluency for choice difficulty, as when prompted to consider the actual reason for the disfluency, or when not making a choice.

Abstract:

Recently, gender-ambiguous (non-binary) voices have been added to voice assistants to combat gender stereotypes and foster inclusion. However, if people react negatively to such voices, these laudable efforts may be counterproductive. In five preregistered studies (N = 3,684) we find that people do react negatively, rating products described by narrators with gender-ambiguous voices less favorably than when they are described by clearly male or female narrators. This is due to the voices creating a feeling of unease related to difficulty understanding the gender of the narrator, what we call social disfluency, that spills over to affect evaluations of the products being described. These effects are best explained by low familiarity with voices that sound ambiguous. Thus, initial negative reactions can be overcome with more exposure.
