What is a key benefit of using statement analysis as opposed to non-verbal cues?

The key benefit of using statement analysis over non-verbal cues is that it allows investigators to avoid establishing norms. Statement analysis involves examining the content of what a person says, focusing on the structure, wording, and detail of their statements to detect inconsistencies or signs of deception. This method does not rely on the investigator's interpretation of non-verbal signals, which can be subjective and influenced by personal biases or preconceived notions.

Using statement analysis helps ensure a consistent and objective approach, as each statement can be evaluated on its own merits without the potential distractions that body language or facial expressions might introduce. By concentrating solely on the verbal content, investigators can derive insights based on linguistic patterns that may indicate truthfulness or deceit.

This approach contrasts with focusing on body language, which can be interpreted variably and may not directly correlate with the truthfulness of a statement. It also remains effective regardless of whether the subject is present for observation of their non-verbal cues.
