First time accepted submitter vrml writes "Critical situations in which participant's actions lead to the death of (virtual) humans have been employed in a study of moral dilemmas which just appeared in the Social Neuroscience journal. The experiment shows that participants' behavior becomes more utilitarian (that is, they tend to minimize the number of persons killed) when they have to take a decision in Virtual Reality rather than the more traditional settings used in Moral Psychology which ask participants to read text descriptions of the critical situations. A video with some of the VR moral dilemmas is available, as is the paper."
"The fundamental principle of science, the definition almost, is this: the
sole test of the validity of any idea is experiment."
