Does Post-identification Feedback Affect Evaluations of Eyewitness Testimony and Identification Procedures?

Two experiments were conducted to test whether post-identification feedback affects evaluations of eyewitnesses. In Experiment 1 (N = 156), evaluators viewed eyewitness testimony. They evaluated witnesses who received confirming post-identification feedback as more accurate and more confident, among other judgments, compared with witnesses who received disconfirming post-identification feedback or no feedback. This pattern persisted regardless of whether the witness’s confidence statement was included in the testimony. In Experiment 2 (N = 161), witness evaluators viewed the actual identification procedure in which feedback was delivered. Instructions to disregard the feedback were manipulated. Again, witnesses who received confirming feedback were assessed more positively. This pattern occurred even when witness evaluators received instructions to disregard the feedback. These experiments are the first to confirm researchers’ assumptions that feedback effects on witnesses translate to changes in judgments of those witnesses.     

Redefining the Nonproliferation Norm? Australian Uranium,the NPT,and the Global Nuclear Revival

Optimists maintain that great powers oppose the proliferation of nuclear weapons and have a moral aversion to their use. The Eighth Review Conference of the Treaty on the Non‐Proliferation of Nuclear Weapons (NPT) in May 2010 produced a final declaration calling for steps toward complete disarmament. Yet recent optimism belies some contradictory, incremental foreign policy decisions taken by countries like Australia and the United States that could produce a change of meaning for the nuclear nonproliferation norm. Building on the “norm life‐cycle” model developed by Martha Finnemore and Kathryn Sikkink, this article links a new constructivist model of normative change to decisions by developed states to expand the global nuclear fuel cycle and provide sensitive nuclear assistance to other countries. An exploratory case study of Australian government policies on nuclear energy and uranium exports (2006‐present), including the possible sale of uranium to India, a non‐NPT signatory, suggests an important role for elite agency in norm redefinition.
