- PublikationAffect or information? Examining drivers of public preferences of future energy portfolios in Switzerland(Elsevier, 2019) Jobin, Marilou; Visschers, Vivianne; Arvai, Joseph; Siegrist, Michael [in: Energy Research & Social Science]The energy transition in Switzerland, as in many other countries, aims to increase the proportion of electricity produced using renewable energy technologies. In this context, governmental agencies and other institutions have attempted to communicate the implications of (domestic) electricity systems through the use of web-based and interactive decision support systems (DSSs). Studies show that, when no additional information is provided, preferences concerning the future electricity mix are mainly driven by the affective reactions that energy technologies evoke. A question remains, however, regarding how people engage with the information provided in a DSS, as well as whether such information is influential in terms of shaping people’s choices. We asked our participants to build an electricity portfolio using a DSS, which modeled the Swiss electricity system. The participants’ political orientation and their affective reactions to different energy technologies guided their information search, as well as the choice of energy technologies within their portfolio. The attention paid to the information provided was not directly related to the participants’ portfolio choices. The selective processing of information, which was based on the participants’ prior attitudes, suggests that they target information they are already familiar with in the DSS. However, this also illustrates a caveat previously identified in motivated political reasoning, since selective information processing, together with the tendency to disconfirm information that is incongruent with prior beliefs, can lead to the polarization of previously held views. As the information provided through the DSS we tested was unable to change the participants’ affective-cognitive evaluation of energy technologies, its use should be carefully considered in light of the possible effects of consolidating existing beliefs.01A - Beitrag in wissenschaftlicher Zeitschrift
- PublikationKnowledge as a driver of public perceptions about climate change reassessed(Nature, 2016) Shi, Jing; Visschers, Vivianne; Siegrist, Michael; Arvai, Joseph [in: Nature Climate Change]It is intuitive to assume that concern about climate change should be preceded by knowledge about its effects. However, recent research suggests that knowledge about climate change has only a limited effect on shaping concern about climate change. Our view is that this counterintuitive finding is a function of how knowledge is typically measured in studies about climate change. We find that if it is measured in a domain-specific and multidimensional way, knowledge is indeed an important driver of concern about climate change—even when we control for human values. Likewise, different dimensions of knowledge play different roles in shaping concern about climate change. To illustrate these findings, we present the results from a survey deployed across six culturally and politically diverse countries. Higher levels of knowledge about the causes of climate change were related to a heightened concern. However, higher levels of knowledge about the physical characteristics of climate change had either a negative or no significant effect on concern. Efforts aimed at improving public knowledge about climate change are therefore not the lost cause that some researchers claim they may be.01 - Zeitschriftenartikel, Journalartikel oder Magazin
