FAQ & Technical Support

A small percentage of people will physically not respond to eye tracking tests. Another group of people might fail for one of the following reasons.

The test taker:

1) has committed a similar, but different behavior than the one being tested for;

2) has been a victim of similar behaviors from others;

3) is covering for a serious crime or behavior of another person;

4) is worried or distracted by another serious behavior or crime they've committed; or

5) misunderstands the test questions.

If you feel that you failed the test but you are innocent, there are several options.

1) evaluate the conditions under which you took the test. If the lighting was bad, the noise levels high, or the stress high, it might have been the environment. The single biggest reason for bad tests are bad test environments.

2) Evaluate carefully the questions you are asking. Is it possible you could construe any of them, even subconsciously, as being guilty?

3) You may simply be one of the small % of people for whom the test does not work. Some people's eyes simply do not respond to cognitive load.

A false negative test is when a test taker who is actually guilty passes the test.

A false positive test is when a test taker who is actually innocent fails the test.

This indicates that the quality of the images is insufficient to score the test. Look at the pictures to make sure you have good lighting conditions and that the camera angle is perpendicular to your eyes.

Unanswered questions are simply those the test taker did not answer.

Unrecognized Answers are those the test did not recognize. A large number of unrecognized answers flags the tests as invalid.

Unexpected answers are opposite of what we expect, which is that the test taker is innocent. If the test taker answered opposite of what we expected, we categorize that answer as a confession. If this happens frequently we flag the test as Not Credible due to Probable Confession.

Data Quality refers to the fidelity of the test data. When a test is administered, audiovisual data are uploaded and securely processed.

The better quality of this data will lead to higher accuracy and faster test scoring.

Data Quality will vary depending on the test taker's device, proximity to the mobile phone, mobile connectivity, and compliance with instructions.

An EyeCanKnow Credibility Score was calculated by patented computer algorithms, which considered various eye responses and reading behaviors to generate the score.

EyeCanKnow credibility scores range between 0% and 100%. A score above 50%-99% indicates a credible reaction or the subject reacted truthfully.

The closer the score is to 99, the lesser the reaction to the issue. A score between 1%-49% indicates the subject reacted deceptively or lied to the question. The closer the score is to 1, the stronger the reaction to the issue.

EyeCanKnow may issue a refund at our discretion if such refund is requested within 2 business days from the purchase date of the test. No refunds will be given after that time.

The refund amount will be equal to the net amount of the total purchase price less any bank card or financial transaction fees. All refunds will be made within 2 business days.
