Corporate scenarios may sometimes call for rapid investigation. It could be due to suspicious activity, theft, misconduct, or fraud. To detect these, people resort to certain devices to navigate the truth. Here’s where the Polygraph test comes in.
This tool can spark both interest and create debate and can help find the truth. But how effective is it? In this article, we’ll break it down for you. Let’s start!
Can You Use a Polygraph Test in Corporate Investigations?
Yes, you can use the polygraph test as a reliable tool to get clarity and thoughtful evidence in corporate investigations.
The polygraph, also known as a lie detector, is an advanced way to monitor physical reactions to detect whether someone is telling the truth or not. Such as breathing, heart rate, stress, and perspiration.
In the corporate context, these tests play a big role in investigations and can be used in various aspects. This includes:
- When an employee faces reasonable suspicion of involvement in a workplace incident resulting in financial loss or injury.
- For specific industries, including security services and pharmaceuticals, tests can be used during pre-employment screening.
- Cases that are related to unauthorised disclosure or misuse of confidential or proprietary information.
- Critical situations where you need verification of employee honesty for compliance or regulatory purposes.
- Addressing suspicions related to workplace misconduct or breaches of company policy.
How Does a Polygraph Test Work & Its Benefits?
A polygraph test works by three main bodily responses: heart rate, blood pressure, and skin conductivity through sensors and electrodes. As a person answers questions, the test monitors their physical reactions to spot signs of stress.
Benefits of Polygraph Testing in Corporate Settings:
- Verifying Statements: Employees can be asked to verify their statements during the internal investigations
- Helps to screen out any suspicious activity or members: When multiple individuals are part of a security breach, the test can shrink the group of potential culprits and help to identify any misconduct.
- Acts as a security checker: It can be implemented in interviews and material reviews during hiring or verifying work.
- Tick off any malicious act on the get-go: The possibility of facing a lie detector test can reduce unethical conduct automatically.
- Creates confidence in important decisions: In areas like finance or cybersecurity and huge deals, it helps put stakeholders at ease.
- Resolve issues: It can help sort out any harassment or accusation cases easily.
The Polygraph Test Process in Corporate Investigations
The polygraph test is a 3-step process. It goes through the
- Pre-Test
- Actual Test
- Post Test
Pre-Test Interview
This stage involves the examiner sitting down with the worker to walk them through the process, establish a connection, and pose simple background questions. It allows the subject to unwind and creates a standard for typical responses.
The examiner will let them know all the questions they’ll ask and the outcome of the test. They will make sure there are no surprises in this, and everything is as clear to them. It’s one of the most fundamental parts of the entire test.
Actual Testing Phase
At this stage, the sensors are attached to the examinee, and the questionnaire starts. Before that, the examiner will conduct control questions or other methods like “Did you ever drink water?” to check for errors. Next, they will look for findings.
There are only 4 relevant questions they might ask, and some irrelevant ones to detect any unusual pattern in the test. Three identical runs are conducted, the last one being the longest. At times, people admit guilt during this part when confronted with clear results.
Post-Test Discussion
After the test is conducted, it can be taken to the business to analyse and form an opinion on it. They can also rule out potential threats or identify suspects and carry out further investigations.
Common Uses of Polygraph Tests in the Corporate World
Economic Loss or Injury
Businesses might use lie detector tests when theft, fraud, or property damage occurs. If company money disappears, a test could help to eliminate or confirm which employees were involved.
Suspected Misconduct
Workplace bullying, rule-breaking, or compliance problems often lack clear evidence. A Polygraph test can help the internal HR process by adding another clue to solve the mystery.
Data Breach Investigations
Cyberattacks often happen because there might be internal misconduct that helps them commit the crime. When computer records don’t show the whole picture, companies might turn to polygraph tests as part of their digital detective work.
Substance Abuse
For workers in jobs where safety is a top priority, like driving or factory work, polygraph tests might check if someone is hiding drug or alcohol use after accidents happen at work.
Pre-Employment Screening (For High-Risk Positions Only)
In some cases, where the job deals with huge money transfers or access to secret systems, companies might use polygraph tests when hiring. This happens more often in fields like cybersecurity, legal, and pharmaceuticals.
Investigations of Specific Incidents
When a handful of people can access a hacked account or damaged item, lie detector tests help narrow down the list of suspects to catch the main culprit easily.
Deter Unethical Activity
The idea of having polygraph tests can help to instill fear into the employees. They are more likely to do the right thing when they know someone might check up on them.
When Should You Refuse a Polygraph?
Here are situations where saying no to a polygraph might be justified:
- If the test is conducted without any specific reason.
- When it’s the sole criterion to punish workers.
- If you weren’t informed of your rights before the test.
- When there are no legal grounds (per EPPA or local law).
- If the examiner doesn’t have any credentials or isn’t trained.
- When its results are the only evidence being used.
In Closing
The polygraph test is an effective way to find any threats; however, it’s not 100% accurate. However, they do bring out around 95% accuracy. So, this test can be used to narrow down the suspects easily.
Make sure you understand the laws governing these tests and always get reliable lie detectors and trusted professionals in this field. At the end of the day, trust is the foundation of any scenario, and these tools are made to protect it, not breach it.
