Most of us believe that we have a good memory. That our memory is like a film recording that we can play back to provide an accurate recollection of events. However, research shows that the truth is much different. Recent studies reinforce the fact that our memories are fallible and unreliable, even though an emotional connection with an event enhances memory formation.

In many trials, the evidence comes down to the credibility and reliability of the testimony of the people who were at the scene of the alleged crime. Credibility refers to the truthfulness of a statement given by a witness. Reliability refers to the accuracy (or veracity) of that statement.
