Abstract
Two recent papers on risk perception models are discussed. In these papers, quantitative analyses are presented of risk perception in relation to risk characteristics as specified in the Psychometric Model, and to cultural biases according to Cultural Theory. This comment points out that the data quality of these two studies is doubtful, with a very small convenience sample and a very low response rate. More importantly, the analyses show the same low levels of explained variance of risk perception as other researchers have found previously, but the authors still draw optimistic conclusions from their data. Such conclusions are unjustified.
