Quizplus · Accepted Answer

Research has shown that highly confident eyewitnesses are not always accurate (choice A is false). Eyewitnesses should be warned that the suspect may or may not be in a lineup to avoid biases and false identifications (choice B is false). However, choice C is supported by research - an authority's confirmation can increase an eyewitness's confidence in her choice, even if the choice is wrong, which is known as the "confidence-accuracy" feedback effect.
