Which statement about barriers during observation is false?

• A. A barrier in front of the witness during observation makes them more credible.
• B. A witness who testifies from a location closer to the events is more credible than one who testifies from a greater distance.
• C. A witness who is paying attention to the event is more credible.
• D. A barrier in front of a witness during observation decreases credibility relative to no barrier.

Answer: (D)

The idea being tested is how observation conditions influence witness credibility. Credibility isn’t determined by the mere presence of a barrier; it’s shaped by how those conditions affect a witness’s ability to observe, recall, and resist external influence. Saying a barrier in front of a witness always decreases credibility is not accurate. A barrier can actually reduce coaching or contamination from others, helping keep the testimony independent. It can also be neutral in effect—having little impact on credibility—depending on the specific setup and factors like distance to the event and the witness’s attention. In contrast, being closer to the event and paying attention are more reliably linked to stronger recall and thus greater credibility. So the statement about the barrier inherently decreasing credibility relative to no barrier is the one that isn’t supported by how observation conditions typically influence credibility.
