Helping Individuals to Understand Synergistic Risks: An Assessment of Message Contents Depicting Mechanistic and Probabilistic Concepts

Abstract: Accumulating evidence shows that certain hazard combinations interact to present synergistic risks. However, little is known about the most effective ways of helping individuals to understand this complex risk concept. More specifically, there is an absence of empirical research that has assessed the relative efficacy of messages that explain either the causal mechanism and/or the probabilistic components of synergistic risks. In an experiment designed to address this issue, we presented participants with mess… Show more

“…Reassuringly, the greater proportion of veridical risk model judgements made by the domain-experts in Study 2 indicates that knowledge of the synergistic risk attributable to certain combinations can be learned. This suggests that laypersons should also be able to acquire a more veridical understanding of the synergistic risk attributable to certain factor combinations, provided they are exposed to effective learning opportunities (for supporting evidence see Dawson, Johnson & Luke, 2012c).…”

“…More recently, researchers have employed alternative methods, such as examining 'possibility judgements' and 'articulated reasoning' to assess individual's judgements and understanding of synergistic risks (see Dawson, Johnson, & Luke, 2012a, 2012c. One innovative approach, introduced by Condit and Shen (2011) in a study concerning public understanding of geneenvironment interactions, required participants to provide risk model judgements rather than risk magnitude estimates.…”

“…Hence, there remains substantial scope for researchers to identify and assess the most efficacious techniques for communicating the complexities of population growth risks. Researchers might start by assessing the extent to which these tasks can be achieved by the approaches that have been employed to communicate these and similar complexities in other risk domains …”

“…For example, the latter (i.e., similar other risks) chanced raising perceptions of radon risk by a riskladder effect (Sandman, Weinstein, and, Miller, 1994) in which people interpret vertical position on a graph as relative risk. People consistently underestimate interaction versus separate risks of the two hazards (e.g., Hampson et al, 1998Hampson et al, , 2000Lee et al, 1999;Lichtenstein et al, 2000; for a more positive view, see Dawson, Johnson, and Luke, 2013), although one person asked for information about synergistic risk. Comparing 20 chest x-rays a year to the similar risk of the regular standard for radon in water elicited an expected comment (from just one participant) that it should be dropped because no one gets 20 x-rays a year.…”
