This research shows that the perceived difficulty of manufacturing a product influences consumers' perceptions of the firm's other products. In three experiments (with 152 participants in Study 1, 86 in Study 2, and 91 in Study 3), participants received information about the quality of a firm's product and then inferred the quality of another product from the firm. When participants believed that the initial product was relatively more difficult to manufacture than the second product, they inferred that the second product would be high in quality. However, when participants believed that the initial product was relatively easy to manufacture, they inferred that the second product would be low in quality. These effects occurred when perceived difficulty of manufacture was manipulated (Study 2) and occurred regardless of whether both products had dissimilar product benefits (Study 1) or whether brand names were present (Study 3).
