Interrogation tactics have long been fascinating, debated, dark, and controversial. You’ve likely seen them in gritty detective movies and tense courtroom dramas. The art of extracting information from individuals comes in countless ways in popular culture. 

But have you ever considered how these methods have evolved? There’s a rich history of interrogation tactics, with strategies ranging from the surprisingly benign to the downright sinister.


In ancient times, methods were often brutal, based on the belief that extracting the truth could only be possible through physical pain or threat. Fast forward to the modern era, and interrogation has become more refined, relying more on psychological manipulation and clever questioning than brute force. 

Yet, despite this progress, the line between ethical and inhumane interrogation tactics is still debated by experts and laypeople alike.

In this article, we will examine the motivations behind different methods, the ethical dilemmas they present, and the effectiveness of each approach.

Ancient Interrogation Tactics

In the ancient world, interrogation tactics were often ruthless. Physical torture was the norm rather than the exception, with methods such as flogging, rack stretching, and waterboarding commonly employed. 

Ancient civilizations like the Romans and Egyptians often used public torture and execution to interrogate and punish. It was not only to extract information but also to instill fear in the population and discourage dissent.

Witch Trials and the Spanish Inquisition

Fast forward to the medieval period, and we see the emergence of infamous events such as the witch trials and the Spanish Inquisition

During these times, the accused often endured horrific torture to extract confessions. The strappado (a form of suspension torture) and the thumbscrew were some of the often-used techniques. 

Although these highly unreliable methods often led to false confessions, it was a common practice throughout Europe.

The Ordeal Trials of the Middle Ages 

Another intriguing example of ancient interrogation methods happened in the medieval ordeal trials. These bizarre, almost mystical tests aimed to reveal the truth through divine intervention. 

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.
