How persuasive is an eyewitness testimony?
In an experiemnt done with a fake roberry, the most convicining evidence was when they just had an eyewitness and circumstantial evidence. As soon as you hear an eyewitness, you are more likely to believe them, especially if you hear them first. Only when you introduced another opposing eyewitness, the amount juree will believe the first witness decrease , but only a little bit. Doesnt have much affect.
How accurate is an eyewitness?
They will alwasy be unreliable to some extent. Shown with the stage robbery in a law classroom, people were all over the place with their description of the man, leading us to believe that no one really know, as both incorrect and correct people were believe majority of the time.
- traivail evidence: should make us doubt more because they are focusing on the random stuff, but give us more confidence to believe them
- confidence inn the witness: creates more confidence in the jury
