Limitations
Our study comes with a few limitations in addition to the proxy for behavior addressed in the discussion. The scales used to measure subjective comprehension and intentions are made of a limited number of items and therefore might not be specific enough to be able to measure the desired construct. Moreover, the research was performed in Norwegian and with Norwegian participants. Norway is a high-trust society, and therefore findings might be context-specific and not generalizable to other countries. Moreover, participants are members of the NAAF—a nonprofit organization delivering advanced lifesaving medical treatment and supported by more than 300,000 members. As the sample used in this study comprised the NAAF members, it cannot be considered a random sample and therefore might not be representative of the general population in terms of education and age distribution. These limitations, along with the little variation and ceiling effects observed for some variables, open a research opportunity for scholars worldwide.
