Introduction
New technologies tend to be welcomed with caution, and people perceive the risks as being high. For example, new information technology (IT), including artificial intelligence (AI) or machine learning, has attracted much media attention. The main narrative is that IT innovations will make many people’s jobs redundant and will lead to mass job losses [New technologies bring benefits as well as risks, and risk-averse attitudes in the general public can affect policy decisions, even if the benefits to the society are quantitatively obvious, and this hesitancy may harm the public good [Nudge theory, in which behavioral change for public good is gently prompted, has been proposed in behavioral economics as a type of intervention that considers irrational human decision making [The successful nudging applications are categorized phenomenologically [We proposed an approach to designing nudges that incorporates insights from evolutionary psychology, using messages highlighting familial support to moderate risk-averse attitudes [Thus, in this study, we identify the message effects on increasing positive attitudes toward IT innovations. We use the same framework as in our previous survey for air pollution caused by industrialization, in which the intervention effects were measured via a randomized controlled trial (RCT). One traditional model for understanding the attitudes toward technology is the technology acceptance model (TAM) and its variations, which mainly assume that perceived usefulness and perceived ease-of-use affect acceptance [The effects are evaluated by segment, including basic segments, such as sex and age. A panel analysis is also performed to identify how each respondent’s attributes contribute to the effects, including personality traits. Especially in relation to personality traits, decision making that is perceived to benefit future generations relies on altruism. We identified that altruism measured as one of Big Five personality traits showed a significant contribution to the effects of similar messages [The remainder of this paper is organized as follows. In Section 2, we describe the settings of the experiments. In Sections 3 and 4 we describe and discuss the results of the experiments, and in Section 5 we provide concluding remarks, including future work.
