Abstract | The relationship between risk and benefit is complex and has been studied in a number of
different ways. Fischhoff et al. (1978) approached the relationship in a novel way, using
psychometric analysis to measure public attitudes regarding the perceived risks and perceived
benefits of certain technologies and activities, finding a negative correlation between perceived
risk and perceived benefit. In a well-powered, pre-registered study we set out to conduct a
replication of Fischhoff et al. (1978) with several adjustments and extensions. Using a simplified
survey design and improved statistical testing, we conducted an exploratory analysis indicating
that (i) participants rated selected technologies and activities from the original study differently
with respect to their perceived risks and perceived benefits and (ii) extending the study to Covid-
19 pandemic items, participants also rated such items differently with respect to their perceived
risks and perceived benefits. In a second extension, we added a third condition to the study to
allow within subjects analyses, which revealed empirical support for the negative correlation on
the participant level between perceived risk and perceived benefit for Covid-19 pandemic items
on an aggregated basis, r(347) = -0.46, p < .001, 95% CI [-0.54, -0.37], and for the majority of
individual items, including Covid-19 vaccines, r(347) = -0.62, p < .001, 95% CI [-0.68, -0.55],
general vaccinations, r(347) = -0.53, p < .001, 95% CI [-0.60, -0.45], lockdowns, r(347) = -0.48,
p < .001, 95% CI [-0.56, -0.39], and handguns, r(347) = -0.46, p < .001, 95% CI [-0.54, -0.37].
Finally, an additional exploratory analysis of item level correlation revealed strong support for
the negative correlation between perceived risk and perceived benefit for our between subjects
analysis, r(16) = -0.63, p = .006, 95% CI [-0.85, -0.22], and our within subjects analysis, r(16) = -
0.69, p = .002, 95% CI [-0.87, -0.33].
