For instance, in the ordeal by water, a suspect would be thrown into a body of water with both hands and feet tied up. According to beliefs at the time, the innocent would float while the guilty would sink.
Similarly, in the ordeal of trial by fire, a suspect must carry a red-hot iron bar a certain distance or walk over a red-hot plowshare. If their wounds healed cleanly, they were considered innocent; if they rotted, they were deemed guilty.
Divine Intervention
These trials relied on the belief that God would intervene to protect the innocent, a notion that seems absurd to us today. However, they held severe implications at the time and could mean the difference between life and death.
The church eventually banned these ordeals in 1215. But they remain a fascinating example of the lengths people have gone to to extract the truth.
Modern Interrogation Tactics
As society progressed, so did the understanding of human psychology. Modern interrogation tactics shifted away from physical coercion and towards psychological manipulation.
Today, law enforcement agencies use various techniques to encourage suspects to divulge information voluntarily.
The Reid Technique
One of the most widely known modern interrogation tactics is the Reid Technique, a psychological approach developed in the 1950s by John E. Reid.
This method involves a three-step process: factual analysis, behavior analysis, interview, and interrogation. The Reid Technique observes the suspect’s body language and verbal cues to determine their truthfulness and then employs manipulative strategies to encourage confession.
PEACE Method
Contrasting the Reid Technique is the PEACE method. It stands for Preparation and Planning, Engage and Explain, Account, Closure, and Evaluate.
It involves a non-confrontational approach in the United Kingdom and several other countries. This method focuses on building rapport with the suspect and encouraging them to share their version of events rather than trying to catch them in a lie.
The Fine Line Between Ethical and Unethical
While modern interrogation tactics have certainly come a long way from the brutal methods of the past, they are not without controversy.
Critics argue that techniques like the Reid Method can still lead to false confessions. Notably, it was a concern among vulnerable populations such as children or those with mental disabilities.
Ongoing debates exist about the ethical implications of using manipulative strategies to extract information, even when they do not involve physical harm.
Looking Forward: The Future of Interrogation Tactics

The evolution of interrogation tactics mirrors our broader understanding of human psychology and ethics. At the same time, the history involves physical torture and intimidation, and the present and future lean towards psychological manipulation and rapport building.
However, this shift is not without its challenges. Persistent debates about the ethics and effectiveness of various tactics underscore the necessity for ongoing evaluation and improvement in this crucial area of law enforcement.
