The confidence of eyewitnesses in their identifications from lineups

The confidence that eyewitnesses expresses in their lineup identifications of criminal suspects has a large impact on crimina proceedings. many convictions of innocent people can be attributed in large part to confident but mistaken eye-witnesses. Although reasonable correlations between confidence and accuracy can be obtained under certain conditions, confidence is governed by some factors that are unrelated to accuracy. An understanding of these confidence factors helps establish the conditions under which confidence and accuracy are related and leads to important practical recommendations for criminal justice proceedings.
