Table 1.
Everyday activities judged by participants and their objective acute risk in MicroMorts (risk of number of deaths per 1 million).
Table 2.
Responses to the previous experiences questionnaire (F = female; M = male; T = total) from n = 284 in analyses.
Table 3.
Correlations between key model predictors.
Fig 1.
Box-plot of subjective risk perception on the 800-pixel line (i.e. responses varied between 0 and 800) for all 20 activities.
Each box represents the interquartile range of subjective risk perception judgements for each activity, with the median crossing within each box, and all data points within 1.5 of the upper and lower interquartile ranges are represented by the whiskers. MM = MicroMort value.
Fig 2.
Scatter plots of linear predicted values (from fixed portion of mixed effects model; of log of 1 + judgment on 800 pixel line) relative to activities varying in their objective MicroMort (MM) risk, numerical ability (average error on symbolic-number mapping task) and prior experience.
Higher values on the y axis represent a higher perceived risk. It can be seen that those who underestimate on the symbolic-number mapping task, perceive risks to be lower, especially for low risk (smaller MicroMorts) activities; and further, those who have undertaken the task previously, perceive risks to be smaller.
