Infidelity and relationship lie detector tests
When trust in a relationship has been shaken, some couples look for a structured way to address one specific question. Here is how that works and what it can and cannot settle.
Why people consider a test
People call about relationship testing for different reasons. Some suspect infidelity and want to address it directly. Others have been accused and want a way to support their own account. Some couples agree together that a neutral process could help them move past one disputed event.
Whatever the reason, the test is about one person's answers to a small number of clearly defined questions. It is not a verdict on the relationship.
Participation must be voluntary
The person being tested must take part freely. A test will not go ahead if the examiner believes someone is being pressured, threatened or forced. If you are thinking about asking a partner to take a test, it helps to talk openly together first about why, what question would be asked, and what each of you will do with the result.
Informed consent
Before testing, the person being tested is told how the test works, what will be asked, who will receive the results, and that they may stop at any time. Adults may sign a consent form, but it is not required. Written consent is required for anyone under 18.
How the questions are set
Broad questions make for unclear results. Rather than "Have you ever cheated?", the examiner helps you focus on something specific, such as whether a particular kind of contact happened with a particular person in a particular period.
What a test can and cannot establish
It can
- Provide a structured, neutral process for one disputed question.
- Give a scored result based on measured eye behaviour.
- Give someone who has been accused a way to support their account.
It cannot
- Prove that someone was or was not unfaithful.
- Guarantee a correct result. Wrong results happen.
- Repair trust, save a relationship, or replace counselling.
Interpreting results carefully
A result is one piece of information from a method with known limitations. Please do not make major decisions about your relationship, finances, children or safety based only on a test result.
If you or someone involved feels unsafe, contact local police or emergency services. A test is not the right step where there is a risk of harm.
Remote or in person
A relationship test can be done in person with EyeDetect or remotely with VerifEye, so neither partner has to travel. How remote testing works · Cost
