Zusammenfassung

Objective We investigated how individuals deal with the limits of their own knowledge and productively cope with their dependence on experts as they engage with the socio-scientific topic of nuclear energy. We scrutinized the effects of content features of an interview text and of individuals’ communicative engagement with the information read. Method In a 2 × 2 factorial design study (N = 273), adult participants opposing nuclear energy read an online interview with a geophysicist. The same factual information was presented, but the geophysicist either took a stance for decommissioning nuclear energy plants or took no stance. After reading, participants were instructed to communicate their own position in an informative or persuasive manner. Dependent measures evaluated participants’ intellectual humility, strategies, perceived easiness of a simple solution, willingness to act and written arguments. Results Expert taking a stance led to lower intellectual humility, higher perceived easiness of a solution and stronger willingness to act against nuclear energy. Having the goal of persuading resulted in participants offering more one-sided arguments. Strategies were not significantly influenced by the independent factors. Conclusions The contrasting effect on individuals’ intellectual humility and willingness to act is discussed from the perspective of climate-oriented action and science education. KEY POINTS What is already known about this topic: (1) Individuals need to rely on experts to gain information and make decisions about scientific topics. (2) How scientific knowledge is communicated affects individuals’ perceptions and understanding of scientific issues. (3) Individuals’ communicative engagement with (socio-)scientific topics affects their metacognitive judgments (e.g., certainty of their own position, consideration of the opposite perspective). What this paper adds: (1) How scientific knowledge is communicated affects individuals’ topic-specific intellectual humility. (2) When an expert takes a clear stance about a socio-scientific issue, this may give more clarity to the individuals and can increase their willingness to act but it can also lower their intellectual humility. (3) Arguing towards a clear standpoint (writing to persuade) can influence individuals’ beliefs in a simple solution.
