Movie Debriefing

How many of you saw something strange during the movie?

Background

Video was made as part of an experiment designed to test people’s “inattentional blindness”

In the original study at Harvard, only 42% of the people noticed the gorilla walking through the scene

This activity illustrates the unreliability of eye-witness testimony

Witnesses vs. Physical Evidence

Most witnesses do not intentionally lie on the witness stand

Human observation is limited by memory, suggestion, and interpretation

Memories can be confused or altered, but physical evidence stays the same

Spot the Difference

Problem

You’ve discovered a problem with the crime scene photos from a recent case. Someone has tampered with the crime scene. See how many differences you can spot between the two photographs of the same crime scene.

I-Witness

+Problem

You were the principle crime scene investigator on a case two years ago.

It is now time for you to testify in court about your findings.

The defense attorney challenges the accuracy of your testimony and implies that you observational skills are not so great.

+

If he can show the jury you are not good at spotting details, he might have a chance of getting his client off.

It is often the case in real life situations that the credibility of expert witness testimony is challenged.

The thoroughness with which they do their jobs is critical.
