Mental Model


An influence diagram is a directed graph, with arrows or “influences” connecting related “nodes.” They were developed by decision analysts as a convenient way to summarize information about uncertain decision situations. For our project, influence diagrams are a convenient way to summarize the expert knowledge upon which a risk communication will be built. The link below will show the expert and lay people diagram created for the risk of carbon monoxide intoxication as an Excel spreadsheet. The yellow boxes note the aspects that were not mentioned by lay people during the semi-structured interviews, but were mentioned by the experts.
