Statement Content Analysis (SCAN) is a technique used to analyze written or spoken statements to identify patterns, inconsistencies, or potential deceptive language.
SCAN involves examining the content, structure, and language used in a statement to assess its credibility and truthfulness.
Here's an overview of how SCAN works:
Contextual Analysis: The first step in SCAN is to consider the context in which the statement was made. Understanding the background, motivations, and potential biases of the speaker is crucial. This helps in identifying any underlying factors that could influence the content of the statement.
Content Analysis: The content of the statement is examined for inconsistencies, contradictions, and omissions. Specific attention is given to the amount of detail provided for various elements of the statement. Discrepancies between what is said and what is expected based on the context or other evidence can be indicators of deceptive language.
Linguistic Analysis: SCAN involves analyzing the language used in the statement, including word choice, verb tenses, pronouns, and sentence structure. Linguistic cues such as hesitations, qualifiers, excessive detail, or avoidance of certain topics can reveal potential deception. Inconsistencies in verb tenses or discrepancies between present and past tense usage may raise concerns about the truthfulness of the statement.
Emotional Appeals: SCAN also pays attention to emotional appeals or attempts to manipulate the listener's emotions. Excessive emphasis on emotional states or dramatic events may be used to divert attention or evoke sympathy, potentially indicating deceptive intent.
Logical Analysis: The statement is examined for logical coherence and consistency. Any logical fallacies, contradictions, or implausible elements within the statement can cast doubt on its reliability. Inconsistencies in the sequence of events, time references, or cause-and-effect relationships are scrutinized.
Contextual Knowledge: SCAN often involves cross-referencing the statement with existing knowledge or external evidence. This can include verifying facts, checking timelines, or consulting relevant sources to validate or challenge the information provided.
It's important to note that SCAN is not a foolproof method for detecting deception. It serves as a tool to identify potential red flags and areas for further investigation. The analysis should be conducted with caution, considering other factors such as nonverbal cues, corroborating evidence, and expert judgment.
