What is a false statement when evaluating information?

The identification of a false statement in this context focuses on the assumption that volunteered information is typically truthful. This statement is misleading because while individuals may offer information in good faith, it does not guarantee its accuracy. People's motivations, perceptions, and memory can skew their accounts, making it crucial for detectives to approach volunteered information with a critical mindset. Thus, assuming that all volunteered information is reliable can lead to erroneous conclusions and undermine the investigative process.

The other statements correctly reflect best practices in evaluating information. Corroboration is indeed essential as it helps to confirm or challenge claims through multiple sources or pieces of evidence. Verifying witness statements is a vital step to ensure their credibility and reliability. Furthermore, the manner in which information is delivered can significantly affect how it is perceived, impacting its overall credibility. These principles help ensure a thorough and accurate examination of information in investigative practices.
