What if they knocked down the library and nobody noticed? The failure to detect large changes to familiar scenes

The purpose of the current study was to investigate people's ability to detect changes to familiar scenes. College students were asked either to identify what was wrong with a picture of a familiar location on their college campus (e.g., the library had been removed from the scene), or to estimate the difficulty of change detection for a hypothetical cohort performing the same task. Performance in the change-detection condition was extremely poor, even when changes were large. Participants who were familiar with the scenes and those who were unfamiliar with the scenes both overestimated the actual levels of change-detection performance. A follow-up analysis indicated that the participants who were unfamiliar with the scenes produced estimations of difficulty that were highly correlated with the mathematical area of the change, whereas participants who were familiar with the scenes produced estimations of difficulty that were highly correlated with the actual difficulty of change detection. The results indicate that people's visual long-term memory for familiar scenes lacks the precision to be able to effectively identify even large-scale changes, although subjectively people believe this should be relatively easy.     

Legal Bans on Pro‐Suicide Web Sites: An Early Retrospective from Australia

There are worldwide concerns that pro‐suicide web sites may trigger suicidal behaviors among vulnerable individuals. In 2006, A ustralia became the first country to criminalize such sites, sparking heated debate. Concerns were expressed that the law casts the criminal net too widely; inappropriately interferes with the autonomy of those who wish to die; and has jurisdictional limitations, with off‐shore web sites remaining largely immune. Conversely, proponents point out that the law may limit access to domestic pro‐suicide web sites, raise awareness of Internet‐related suicide, mobilize community efforts to combat it, and serve as a powerful expression of societal norms about the promotion of suicidal behavior.     

The Axes of Debt: A Preface to Three Essays

This is a preface to three essays on different aspects of ontological and economic debt as themes in religious ethics. It frames their contribution by arguing that debt is central to traditions of philosophical and religious ethics yet is woefully neglected as a thematic problem and problematic in contemporary iterations of these traditions. In order to situate debt as a central moral concern, it is argued that any consideration of debt must wrestle with how debt exists on two axes. One is the axis of ontological and economic debt. The other is the axis of debt as an expression of mutuality and debt as a mode of domination. These axes generate deep ambiguities regarding the moral status of debt. But contemporary religious and philosophical ethics struggles to articulate, let alone address, this ambiguity due to being wedded to modern conceptions of the autonomous subject. The essay closes by setting out the themes of the three essays, the connections between them, and how they can be a catalyst for further reflection on this vital but under‐researched topic.
