The Key Role of Experiential Uncertainty when Dealing with Risks: Its Relationships with Demand for Regulation and Institutional Trust

Abstract

The results of a survey and an experiment show that experiential uncertainty-people's experience of uncertainty in risk contexts-plays a moderating role in individuals' risk-related demand for government regulation and trust in risk-managing government institutions. First, descriptions of risks were presented to respondents in a survey (N = 1,017) and their reactions to questions about experiential uncertainty, risk perception, and demand for government regulation were measured, as well as levels of risk-specific knowledge. When experiential uncertainty was high, risk perceptions had a positive relationship with demand for government regulation of risk; no such relationship showed under low experiential uncertainty. Conversely, when people experience little experiential uncertainty, having more knowledge about the risk topic involved was associated with a weaker demand for government regulation of risk. For people experiencing uncertainty, this relationship between knowledge and demand for regulation did not emerge. Second, in an experiment (N = 120), experiential uncertainty and openness in risk communication were manipulated to investigate effects on trust. In the uncertainty condition, the results showed that open versus nonopen government communication about Q-fever-a zoonosis-led to higher levels of trust in the government agency, but not in in the control condition. Altogether, this research suggests that only when people experience relatively little uncertainty about the risk, knowledge provision may preclude them from demanding government action. Also, only when persons experience uncertainty are stronger risk perceptions associated with a demand for government regulation, and they are affected by openness of risk communication in forming institutional trust.

Consumer reactions to unfamiliar technologies: mental and social formation of perceptions and attitudes toward nano and GM products

“…surface chemistry, solubility and possibly shape' (Maynard et al 2006). The ensuing uncertainty poses great challenges for the development of appropriate risk governance strategies and might reduce public confidence in nanotechnologies (Jahnel 2015;Pidgeon, Harthorn, and Satterfield 2011;Poortvliet and Lokhorst 2016;Scheufele et al 2007). Historic experience with other unfamiliar technologies, for example, genetically modified organisms, suggests that the public perceptions of nanotechnology and its risks will be critical for successful marketization, but also the adoption of reasonable risk-avoiding behaviors when handling nanomaterials or products that contain nanomaterials.…”

Social-cognitive determinants of the tick check: a cross-sectional study on self-protective behavior in combatting Lyme disease

“…Knowledge regarding ticks, the tick check and Lyme disease was measured with ten statements that participants could answer with ‘true’, ‘not true’ or ‘I don’t know’, cf. [ 26 ]. For each correct answer the participants received one point, while a wrong answer and ‘I don’t know’ yielded zero points.…”

Peer Review #2 of "Reviews on common objectives and evaluation indicators for risk communication activities from 2011 to 2017 (v0.1)"

“…Over 60% were related to medicine. Studies classified as "other" included those addressing humanwildlife conflicts [35] and traffic safety [36,37], as well as studies that used a risk scenario or involved multiple risk domains to investigate effective means or to assess intrapersonal and other factors of risk communication [38,39]. Five studies (2%) fell in multiple study fields.…”
