 The role of values in science has been particularly controversial in issues of risk. Risk assessments have frequently been criticized for containing “hidden” values that induce a too high acceptance of risk (Cranor 2016; 2017; Intemann 2016; Heinzerling 2000). There is also a discussion on the need to strengthen the impact of certain values in risk assessment, such as considerations of justice (Shrader-Frechette 2005a), human rights (Shrader-Frechette 2005b), and the rights and welfare of future people (Caney 2009; Ng 2005). Issues of risk have also given rise to heated debates on what levels of scientific evidence are needed for policy decisions. The proof standards of science are apt to cause difficulties whenever science is applied to practical problems that require standards of proof or evidence different from those of science.
