 Although most of the above-mentioned meanings of “risk” have been referred to by philosophers, a large part of the philosophical literature on risk refers to risk in the more informal sense that was mentioned at the beginning of this section, namely as a state of affairs in which an undesirable event may or may not occur. Several philosophers have criticized the technical definitions of risk for being too limited and not covering all aspects that should be included in risk assessments (Buchak 2014; Pritchard 2015; Shrader-Frechette 1991). Linguistic evidence indicates that technical definitions of risk have had virtually no impact on the non-technical usage of the word (Boholm et al. 2016).
