Passage Summary: Psychologists think that when people are wrongly convicted, it is often because a witness pointed at the wrong person.

Conclusion: Misidentification by eyewitnesses is a frequent cause of wrongful convictions in criminal trials.

Reasoning: Eyewitness testimony is a staple in almost every criminal trial.

Analysis: This is a 'Strengthen EXCEPT' question, which means four of the answers will provide evidence that eyewitnesses are unreliable or that their mistakes lead to bad verdicts. The argument assumes that eyewitnesses actually make mistakes and that these mistakes are a decisive factor in the jury's decision. You should look for the one answer choice that either has no effect on the hypothesis or perhaps even suggests that eyewitnesses are more reliable than the psychologists think. Human memory is notoriously fickle, so any data confirming that fallibility would typically support the psychologists.
