Which of the following is NOT a common collection method in counterintelligence?

Negotiation tactics are primarily associated with conflict resolution and communication strategies rather than being a method specifically employed for gathering intelligence. In the context of counterintelligence, collection methods refer to systematic processes used to gather information about potential threats or activities related to espionage, sabotage, or other forms of illicit information gathering.

Open Source Intelligence involves collecting and analyzing information that is publicly available, such as news articles and company reports. Human Intelligence pertains to personal interactions and the recruitment of individuals to obtain sensitive information, while Signals Intelligence involves intercepting communications and electronic signals to acquire data vital for understanding security risks.

Negotiation tactics, while they may be utilized in diplomatic or security contexts, do not directly fit into the category of traditional intelligence collection methods as they do not primarily focus on data gathering or assessing threats. This distinction underscores the specific nature of intelligence collection in counterintelligence efforts compared to general negotiation strategies.
