I don’t see what the difference is between this performance and one of the earlier experiments in social psychology by Milgrom and Zimbardo. There’s no way she didn’t get the idea from them. So, to me, this is neither original nor interesting.

In general, I don’t see the point of conceptual art, as it presupposes that the artist has some privileged perspective on the world that they can enlighten us all with. For me, this is a problem much better suited to the scientific method. And anyway, if the only point of your art is some abstract theory, why not write it out clearly on a single sheet of paper? I know it won’t win you the Turner prize, but it will save us all a lot of time.
