Psychological drivers in the adoption of morally controversial innovations: the moderating role of ethical self‐identity

The present article conceptualizes morally controversial innovations as a category of innovations that raise ethical issues due to their potentially undesirable long‐term consequences on society or the natural environment. Then, it analyzes the case of biofuel crops by applying an extended version of the theory of planned behavior, which includes moral norm (i.e. the personal convictions of what is wrong or right for society) and ethical self‐identity (i.e. the extent to which one perceives himself/herself as an ethical person). The obtained results show that attitude and subjective norms are positively related to farmers' intention to grow biofuel crops. Yet the intention of those farmers with a higher ethical self‐identity is also influenced by perceived behavioral control and moral norm. In particular, moral norm negatively affects their intention to grow biofuel crops, thus restraining the adoption of this innovation. Implications for theory, as well as for policymakers interested in promoting the diffusion of morally controversial innovations, are discussed.
