Which statement about physical evidence is true in relation to eyewitness testimony?

• A. Physical evidence is more reliable than eyewitness testimony
• B. Eyewitness testimony is always more reliable
• C. Physical evidence is less reliable than eyewitness testimony
• D. Physical evidence cannot be compared to eyewitness testimony

Answer: (A)

The key idea here is how reliability is affected by objectivity versus memory. Physical evidence provides objective, testable data that can be measured and verified—for example, fingerprints, DNA, surveillance footage, or trace materials. Eyewitness memory, by contrast, depends on perception and recall, which can be influenced by stress, lighting, duration of the event, attention, delays in reporting, and even questioning methods. Because human memory is prone to errors, physical evidence tends to offer a more dependable basis for establishing what happened. That’s why, when available, physical evidence is considered more reliable than eyewitness testimony. Eyewitness accounts can be valuable but are not always accurate, and there are many well-documented ways memory can mislead. The idea that physical evidence is less reliable isn’t supported in general, and saying physical evidence cannot be compared to eyewitness testimony isn’t correct because investigators routinely weigh and corroborate both types of information.
