One requirement for the formation of an Institutional Animal Care and Use Committee is that they include a community member who embodies the values of the general population. This study’s aim is to investigate whether community members use moral arguments when deliberating a case of nonhuman animals used in experimentation. To this end, we tested the responses of community members in a situation similar to those confronting members of IACUC. The participants’ evaluation of the protocol was consistent with the mandates (...) of IACUC. We also found that overall no moral argument played a significant role in their evaluation of a protocol. Only arguments based on loyalty to the human species played a moderate role in the evaluation of using animals in experimental research, in a way similar to using some moral arguments regarding the importance of human welfare to justify the use of animals in experimental research.
