What does "double blind" refer to in the context of eyewitness procedures?

In the context of eyewitness procedures, "double blind" refers to a method where both the administrator of the identification procedure and the witness being asked to make an identification are unaware of the suspect's identity. This approach helps to minimize potential biases and influences that could affect the witness's decision-making process.

When the administrator knows who the suspect is, their behavior or subtle cues may inadvertently lead the witness toward a particular person, even if unintentionally. By ensuring that neither party has prior knowledge of the suspect, the integrity of the identification process is upheld, and the reliability of the eyewitness testimony is enhanced. This methodology is crucial in criminal justice to prevent wrongful accusations and to support the accuracy of eyewitness accounts.

The other options do not accurately define "double blind" in this specific context; they either describe single blind conditions or other non-relevant identification methods.
