The nature, causes, and effects of skepticism on technology diffusion.

Although skepticism is involved in technical change and scientific revolutions, surprisingly, the literature lacks a systematic analysis of the different forms, causes, and roles of skepticism in the diffusion of innovation. This paper defines, identifies and models different types and causes of skepticism and their role in technology adoption. The paper identifies and studies: skepticism involving the characteristics of the technology and the producer; skepticism that induces to disbelieve market signal; and comparative skepticism i.e., skepticism produced by an unbalance relationship between the perceived complexity of the problem and the solution. Among the theoretical findings of the paper and regarding skepticism on market signals, we found that the non-differentiability and oscillation of diffusion rates occur if individuals use the information on diffusion rates as proxy of the probability of technology working and modify this probability according to their skepticism. • Although scepticism is involved in technical change, general analysis of the different forms, causes and role of scepticism in innovation diffusion do not exist. • We developed a dynamic model of decision-making and innovation diffusion that incorporates technology diffusion and trust/scepticism. • Scepticism modifies market signals. • The model contributes to understanding mechanisms behind technology adoption and diffusion: adoption delay, adoption without social interaction, and oscillation of diffusion rates.
