Which statement about leading questions in marine casualty witness interviews is correct?

In a marine casualty investigation, the concept of 'normalization of deviance' describes:
Answer: The gradual acceptance of unsafe practices as normal because they have not previously resulted in an accident
Normalization of deviance, identified by sociologist Diane Vaughan, occurs when repeated rule violations without negative consequences lead crews to treat unsafe behaviors as acceptable.
What is the significance of documenting a witness's demeanor and non-verbal behavior during a marine casualty interview?
Answer: It provides context that may help assess the credibility and reliability of the witness's statement
Non-verbal cues such as hesitation, eye contact, and body language can inform the investigator's assessment of a witness's confidence and truthfulness.
