“Ten Million Readers Can’t Be Wrong!”, or Can They? On the Role of Information about Adoption Stock in New Product Trial
Most new-product frameworks in marketing and economics as well as lay beliefs and practices hold that the larger the stock of adoption of a new product, the greater the likelihood of additional adoption. Less is known about the underlying mechanisms as well as the conditions under which this central assumption holds. In a series of field and consequential choice experiments I demonstrate the existence of non-positive and even negative effects of large adoption stock information on the likelihood of subsequent adoption. The results highlight the degree of homophily with the adopting stock as well as the level of customer uncertainty as key characteristics determining the nature of the effect of stock information. In particular, information about a large existing adoption stock generates a positive effect on adoption only under moderate customer uncertainty combined with sufficient homophily; in other levels of uncertainty and/or homophily the effects range from null to negative. This is the first direct test and demonstration of the intricate role of information about a large stock of adoption in the new product diffusion process, and carries direct implications for marketers.
