How does the self-fulfilling prophecy affect an investigator's success in obtaining a confession?

The self-fulfilling prophecy refers to the phenomenon where an individual's expectations about another person or situation can lead to behaviors that cause those expectations to come true. In the context of an investigator obtaining a confession, if the investigator holds higher expectations about successfully getting a confession, their demeanor, questioning techniques, and overall approach may shift positively.

For example, an investigator who believes that they will successfully obtain a confession may exhibit greater confidence and assertiveness, which can create a more conducive atmosphere for the suspect to confess. These higher expectations can enhance the investigator’s ability to read the suspect’s verbal and non-verbal cues, allowing for more effective communication.

Moreover, when an investigator believes in their ability to elicit a confession, they may approach the situation with enthusiasm and motivation, fostering a rapport with the suspect, which can further encourage them to open up and reveal information they might have otherwise withheld. Thus, the investigator’s mindset and expectations can significantly influence the dynamics of the interaction, ultimately leading to an increased likelihood of obtaining a confession.
