Introduction
Explore the first ten powerful time-tested methods, techniques, and technologies, which are the oldest and most well-known approaches that people have used to detect lies.
They are highly effective in uncovering lies and revealing truths, but fear not; in Part 2, details the more modern and cutting-edge methods, and provide context and explanations for each and their strengths and limitations to expand your toolkit to become a skilled truth-seeker.
However, just like teaching someone an intriguing card trick, understanding the techniques to determine guilt is only the beginning.

Baseline Testing
Before you read on, it's vital to understand the importance of baseline testing. Baseline testing is a technique that allows you to observe someone's normal behaviour and body language by asking questions to understand their typical responses. Later, their behaviour and reactions are compared to their responses when asked about a specific topic, enabling us to identify any discrepancies or clues that may indicate if they're telling the truth.
This technique becomes particularly valuable when determining deception, especially in areas like the power of persuasion, polygraph tests, investigating, body language, and psychology..
However, consider the legalities, ethics, and morality of using these techniques before doing so.
1. Torture
Exploring the Reality of Torture in Detecting Deception
As we delve into the murky world of deception detection, it's vital to acknowledge a method shrouded in controversy – torture. While this article explores various techniques, I must make it clear: I utterly condemn the use of torture for extracting information.
Throughout history, torture has reared its ugly head in various forms – a tool for punishment, intimidation, and interrogation. Despite international laws banning its use, it endures in some corners of the world, both officially and in the shadows.
Think waterboarding, electric shocks, sleep deprivation, threats, and even sexual assault – these are just some of the horrific methods employed. Sadly, echoes of such cruelty can even creep into everyday life, disguised as "discipline." However, let's be crystal clear: such tactics, whether a parent's harsh punishment or a teacher's isolating punishment, have no place in a humane society.
Research paints a stark picture of torture's futility. Studies by groups like the International Rehabilitation Council for Torture Victims show that under such duress, people are more likely to confess to anything, truth be damned. This, in turn, poisons the well of truth-seeking, leading to unreliable information and ultimately hindering justice.
Therefore, we must collectively reject the very notion of using torture as a tool for uncovering truth. It not only violates fundamental human rights but also proves demonstrably ineffective, leaving truth and justice obscured in the darkness
2. Bribery
Bribery is a sensitive and controversial topic, but there are situations where offering incentives or rewards can promote honesty and cooperation. Whether receiving a sweet treat as a child for finishing our greens or a couple making a deal where the husband agrees to go to the wife's favourite restaurant in exchange for watching the game later, bribery can subtly find its way into our lives.
For example, parents can offer rewards or incentives to encourage their children to tell the truth or cooperate with household rules.
Journalists may use bribery to persuade sources to provide truthful information for a story and are willing to speak on the record.
If you witness misconduct or illegal activity in your workplace, you can report it through a whistleblower program. This program may offer financial rewards and protection to those who come forward with information that leads to the successful prosecution of the wrongdoer.
Witnesses in criminal cases may be reluctant to come forward with information due to fear of retaliation. Witness protection programs offer incentives such as relocation, new identities, and financial support to encourage witnesses to testify truthfully. Law enforcement officials may offer plea bargains or reduced sentences in exchange for truthful testimony or information.
3. Truth Serum
The Power of Chemicals: Exploring the Use of Truth Serums.
You may have seen it in movies or TV shows, portrayed as a sinister substance used by people to get suspects or captives to confess. Truth serums, a general term that refers to a variety of drugs used for over a century, and the first recorded use of a truth serum was in 1903 when a New York police officer named Charles Becker used 'ether' to extract a confession from a suspect.
Sodium pentothal, also known as thiopental, thiopentone, or Trapanal, is a barbiturate that gained popularity as a 'truth serum' during the 1950s and 1960s. Initially used in military settings during World War II to aid soldiers in recovering from traumatic experiences, its applications expanded to include psychiatric treatments. However, concerns regarding its effectiveness and safety led to a decline in its use during the 1970s.
I find it fascinating that a substance can make people more open to telling the truth. However, drugs that have this effect should only be used under the guidance of a licensed medical professional and with the consent of any willing participant. Any use outside this context could lead to legal and ethical consequences.
The truth will set you free, but first it will piss you off.
Truth serums alter a person's consciousness, making them more suggestible, less inhibited, and more likely to reveal the truth, but they can also lead to false confessions. Truth serums are illegal in law enforcement interrogations but in certain medical settings, primarily treating specific psychiatric disorders. Other countries, such as China, Russia, and North Korea, continue to employ these serums.
Many countries have restrictions on truth serum drugs, although they are used in medical settings. However, certain countries, including China, India, Russia, and North Korea, still use truth serums in interrogation.
After the 911 attacks on the US, a former head of America's FBI and CIA suggested that truth drugs might be more effective than harsh interrogation methods like torture in penetrating the minds of al-Qaeda suspects.
However, these drugs should only be used under the guidance of a licensed medical professional, and with the consent of a willing participant. Any use outside this context can lead to legal and ethical consequences.
4. Ethanol/Alcohol
Liquid Courage: The Use of Alcohol in Extracting the Truth.
Is it true that alcohol loosens the tongue and promotes honesty? Let's explore the relationship between alcohol and truthfulness.
How often have we drunkenly professed love to people we don't love? Although it's commonly believed that alcohol increases truth-telling or 'liquid courage,' the reality is more complex and depends on various factors.
Alcohol is a depressant that affects the central nervous system, which can lead to a range of behavioural and cognitive changes. In some cases, alcohol can lower a person's inhibitions, making them more likely to speak their mind or reveal information they may otherwise keep to themselves.
However, alcohol can also impair a person's judgement and cognitive abilities, making it difficult to distinguish between what is true and what is not. Studies have shown that alcohol can impair memory recall, making it more likely that a person will forget or misremember information.
Furthermore, the effects of alcohol on truth-telling can vary depending on individual factors, such as a person's personality, mood, and the amount of alcohol they have consumed. Some people may become more talkative and honest when they drink, while others may become more withdrawn or defensive.
While alcohol can lower inhibitions and lead some people to speak more freely, its effects on truth-telling are unpredictable and unreliable. Is alcohol a truth serum?
5. Power of Persuasion
Unleashing the Power of Persuasion for Unearthing Truth and Detecting Deception.
The art of persuasion: techniques for getting others to tell the truth dates back to Ancient Greece and Rome has been employed for centuries to shape individuals' thoughts, beliefs, and behaviours across diverse domains such as politics, religion, and marketing, highlighting its potential for both positive and negative impacts.
If you think about it, we've all used persuasion in some way to get what we want. But when it comes to getting to the truth, persuasion can be a powerful tool, whether to alter a friend's mindset to come clean about a mistake they made or encourage someone, to be honest about something. Consider the following examples:
Contrast Principle: Have you ever noticed that when presented with two options, the second one seems much worse if it's significantly different from the first? Here's how it works: when someone is lying to you, you can present them with the option of either telling the truth or facing a negative consequence. By contrasting the negative of lying with the alternative of telling the truth, the person is more inclined to choose honesty.
Minimisation is often used in law enforcement interrogations to make them feel less guilty about something they have done. It works by downplaying the severity of the offence and making the person feel like they are not alone. Using the following statements creates an atmosphere where the person feels less judged for what they have done. Such as "I can tell you're feeling stressed about this. It's okay to feel stressed". "I know you can do this" (admit their guilt). Or parent: "You look like you're feeling guilty" and: "It's okay to make mistakes". "I'm here for you." "Everyone makes mistakes," or "You're not the first person to do this."
Some people lie by lying about the lie and changing certain details to see or gauge the reactions of someone who also knows the lie.
Mirroring technique, when you want someone to open up about dishonesty, mirroring (synchronising) their body language is essential. By "subtly" copying their gestures, expressions, and posture, you build a rapport and create a comfortable atmosphere. This non-verbal mirroring shows you are in sync with their emotions, making them feel heard and understood. It encourages them to be more willing to share their feelings and experiences, fostering a truthful and open conversation between you both.
Repetition is a powerful tool to enhance the persuasiveness of your message. When you suspect someone's lying, repeating the same questions or statements increases the likelihood of exposing their deception or making them uncomfortable enough to reveal the truth. By restating key questions, you create opportunities for individuals to provide consistent information and potentially expose any discrepancies in their responses. It pressures them to reconsider their initial answers and may lead to unintentional slips or reveals of the truth.
Repeating all the above examples in various ways, at different times, in different settings, and with different individuals present can be effective in uncovering deception, as it catches the person off guard, allows for observation of any changes in their story over time, reveals potential alterations in behaviour based on the context, and helps assess if their narrative differs depending on the audience.
While using these methods, maintain a calm and non-judgmental demeanour, offer support, exhibit patience because it may take time for the person to open up and remain persistent without giving up if the truth does not come to light right away.
6. Polygraph
I'm sure you've heard of the polygraph test( lie detector) tool for detecting deception, but unfortunately, it's not as financially accessible as other techniques. Polygraph tests record physiological responses like respiration, perspiration, blood pressure, and pulse rate. This test has gained both recognition and criticism. While some consider them a reliable tool, others dismiss them as "pure pseudoscience" and "quackery."
The cost of a polygraph test can vary. In the UK, a certified professional may charge anywhere between £300 and £2,000, with reported accuracy levels of 95% to 98%. There are many devices online that claim to detect lies. The cost of these devices ranges from £100 to £2,000. Higher-priced options often claim to offer accuracy rates of 80% to 99%, while cheaper alternatives have received negative customer reviews..
To make an informed decision when selecting a polygraph examiner, view their certification, credentials, and feedback from previous clients.
However, keep in mind that the polygraph test is not fool proof. It can be manipulated or cheated, and various tutorials and techniques are available online to help individuals pass the test. Additionally, individuals skilled in deception, such as psychopaths or sociopaths, may produce false negatives, making it challenging for the lie detector to detect their lies. In addition, you need a willing participant.
7. Investigating
Cracking the Code of Lies: A Journey into Investigation Techniques the Code of Lies.
Investigative services are a valuable tool for anyone who needs to gather evidence or information. Whether you're a law enforcement officer, a private investigator, or simply a concerned citizen, investigative services can help you get to the bottom of what's going on.
Witness interviews are a valuable tool to gather information about crimes and events. By carefully questioning witnesses, you can obtain information to help you get to the truth. For example, a witness may be able to provide information about the suspect's appearance, whereabouts, clothing, or vehicle. They may also be able to provide information about the sequence of events leading up to the deceit.
Cognitive load tests detect deception by measuring the person's cognitive load while performing a task and answering questions. If the person is lying, their cognitive load may be higher, making it more difficult for them to complete them. For example, when a person performs a task while answering questions about specific events, their cognitive load increases if they are not truthful, potentially leading to mistakes.
Social Network Analysis involves analysing social networks and connections to uncover hidden relationships or connections that may be relevant to the investigation. It's like unravelling a web of connections to understand who knows who and how they are linked.
Crime Scene Investigation involves collecting and analysing physical evidence at a crime scene to reconstruct events and identify suspects. It's like piecing together a puzzle to reconstruct what happened and identify possible suspects. They also use tools and equipment to collect evidence not visible to the naked eye, such as trace evidence, footwear prints, clothing fibres, fingerprints and blood spatter.
Covert Surveillance allows you to conduct investigations to discreetly monitor the activities of the person you're looking into. It's like being a secret observer, carefully gathering evidence of their actions and behaviour. This personal approach enables you to uncover valuable information that may go unnoticed.
Trust your gut instinct. If you get the feeling that the witness is not being truthful, don't be afraid to ask follow-up questions.
Forensic Accounting involves analysing financial records to uncover evidence of financial wrongdoing, such as fraud, embezzlement, or money laundering, to uncover hidden patterns or discrepancies that reveal illicit activities.
Computer Forensics examines digital devices and data to uncover evidence of wrongdoing, including deleted files, internet activity, sand social media posts. and other digital footprints. If you suspect that someone is lying to you, you may want to consider hiring a computer forensic examiner to help you to recover deleted files, track internet activity, and identify other evidence that may be relevant.
Undercover operations can gather information or evidence from blending in and building trust with the individuals involved. These operations require individuals who can think quickly and make quick-thinking decisions to avoid detection. When integrated with other investigative techniques, undercover operations provide a more complete understanding of a crime or criminal activity. However, the use of these operations comes with risks and dangers.
Explore Connections: To learn about a person's regular places and the people they interact with, talk to individuals who are familiar with them, such as hairdressers, barbers, bartenders, waitstaff, and regular customers or clients. Discreetly ask about their behaviour, recent changes, and personality. This may reveal any suspicious activities or motives. If needed, offering a bribe can be helpful.
Remember, These techniques are only as good as the people who use them. If you need help gathering evidence, consider hiring a private investigator who has experience and resources that can be help uncover the truth.
8. DNA
DNA testing can be a powerful tool that involves the analysis of genetic materials such as hair, blood, saliva, or skin cells to determine an individual's identity or to link them to a specific event or crime. DNA can identify the presence of a suspect at a crime scene or exclude an innocent individual from suspicion, making it an effective tool for identifying deception in certain situations. Examples include;
Paternity tests: DNA can determine the biological relationship between a child and a potential father. If someone denies being the father of a child, a DNA test can provide irrefutable evidence.
Criminal investigations: DNA can link a suspect to a crime scene or eliminate a suspect if they claim they were not at a crime scene.
Identifying Humans, In cases of missing persons or mass disasters, DNA analysis can establish the identity of human remains in situations such as missing person cases or mass disasters.
Immigration cases: DNA can be used to confirm biological relationships between family members in immigration cases where proof of a genetic connection is required.
Medical diagnosis: DNA can determine if someone has a genetic predisposition to a condition or disease where someone has lied about their medical history.
Paternity fraud cases: DNA can prove that someone has falsely claimed paternity in cases where financial support or custody is at stake.
Historical investigations: DNA can effectively determine the genetic makeup of historical figures or accurately identify unknown family members in genealogy research.
DNA analysis is highly accurate and efficient, providing results with at least 99.999% certainty in just a few days.
DNA testing is not the best tool for detecting deception, as it focuses on identifying 'genetic markers' and 'establishing biological relationships' rather than detecting lies or deceit. The presence of someone's DNA at a crime scene, on a victim, or on an item doesn't automatically imply guilt, as there are several innocent explanations, such as being in the area at the time of the crime or touching an object later involved in the crime.
9. Body Language
Body Talk: Decoding Deception through Verbal and Nonverbal Clues.
Body language unveils emotions and thoughts, eliminating the need for traditional methods. Take note of the subtle movements and behaviours outlined below when studying responses.
Voice: Changes in pitch or tone, stuttering or hesitation, or a sudden increase in speed or volume can be indicators of deception. According to studies, a person's vocal tone deviates from their normal baseline in a high percentage of deceptive statements, with some estimates as high as 95% — a highly reliable indicator.
Eyes: When someone lies, they may avoid eye contact or look away briefly, potentially indicating they are trying to gather their thoughts. * They may also rub their eyes or have a prolonged stare. * People blink less when lying and blink more before responding to 'relevant' information and after responses to 'irrelevant' information. * The timing and frequency of eye blinks may be related to cognitive effort and processing demands, and may therefore be a potential marker of deception. * If they avoid eye contact, look away briefly, or show signs of fear or discomfort when asked questions, it could be a sign that they're lying.
Mouth & Voice/Speech: People's lips are sensitive to emotions and can be hard to control during stress or deception. Tensing lips, lip biting, and biting the inside of the cheek can indicate that someone is holding back information or not being truthful. * Clearing the throat or gulping. * Hesitation is often a sign that someone is trying to think of a lie, provide false information or contradict themselves.
Truth is like medicine, it may not taste good, but it's good for you.
Nose: Studies have shown that the myth about touching one's nose as an indicator of lying is false. Touching one's nose is a pacifying behaviour to relieve stress, possibly due to discomfort from telling a lie or being accused of something they didn't do.
Hands: Fidgeting or manipulating objects, such as touching or rubbing the face, covering the mouth or eyes, or placing the hands in pockets, can be signs of discomfort and stress, which may be signs of nervousness or deceit.
Other cues include: Sweating, blushing, and excessive or unnecessary details when discussing the situation. * A sudden loss of apatite. * Reacting with anger' when falsely accused. *An individual's dodgy and suspicious behaviour.
However, what one person may consider suspicious behaviour, such as someone acting shifty or suspiciously, may be deemed normal behaviour by another person. Also, different cultures and individuals have unique body language cues and interpretations, and some people may be more skilled at lying than others, making it more difficult to detect deception.
10. Psychology
Psychology is just another word for mind games. Here are some examples of mind games and psychology that could be used to get people to reveal the truth: Some examples below.
Playing the "blame game": This technique involves blaming yourself for something to get someone else to confess. For example, if you suspect your child broke a vase, you could say "I'm sorry I left the vase in such a precarious position, I should have been more careful." This can make the child feel guilty and more likely to confess to breaking the vase.
The power of silence is a powerful tool: Sometimes, simply remaining silent and allowing an awkward pause in the conversation can make the other person feel uncomfortable and more likely to fill the silence with information or a confession.
The mirroring technique involves mirroring the body language and tone of the person you're speaking to build rapport and make them more comfortable sharing information. For example, if you suspect your spouse is hiding something from you, you could mirror their body language and tone and say, "I feel like you're not being completely honest with me. Is there something you want to tell me?"
The truth is too much for some people to handle, so they choose to live in denial.
The "good cop, bad cop" routine technique involves two people taking on different roles — one as the "bad cop" who is confrontational and aggressive, and the other as the "good cop" who is sympathetic and understanding. This can make the person being questioned more likely to open up to the "good cop." For example, if you suspect your child is lying about where they were the previous night, one parent could take on the role of the "bad cop" and interrogate the child, while the other parent takes on the role of the "good cop" and offers support and understanding.
The "I know what you're thinking" technique involves using empathetic language to show the person that you understand their perspective and can relate to their situation. This can make them more likely to open up to you and share information. For example, if you suspect your teenager is struggling with depression, you could say, "I know what it's like to feel sad and hopeless. It's okay to talk to me about it, I'm here to listen".
Persistence. If you're observing their body language, don't just ask them once, bombard them with questions asking them the same question in various ways, such as, "Did you steal the money?", "you wouldn't steal from me would you"?. "I would hate to think it was you who stole that money?". And "I feel terrible when people lie to me, let alone steal."
Reverse Psychology: This involves trying to get the person to reveal the truth by suggesting that you already know the answer. This can make the person more likely to reveal the truth, as they may feel that the deception has already been uncovered.
Summery
Congratulations on completing Part 1 of this crash course on detecting deception! By now, you've learned ten valuable techniques to help you uncover the truth. While there's no foolproof method to determine if someone is lying, knowing the signs of deceit can enhance your ability to identify deception.
Approach these situations with an open mind. Trust your instincts and consider conducting a further investigation when needed. Fairness is essential, and if you suspect a crime, report it to the authorities who specialise in deceit.
Stay calm, non-judgmental, and patient. It may take time for them to open up. Let them know you're there for support, regardless of the outcome.
This is the first part of your journey to mastering the art of detecting deception. In Part 2, you will explore ten more techniques to expand your knowledge. Keep up the good work, and best of luck in your pursuit of truth!
