Two Tests. One Truth.
At Australian Polygraph Services, we’re proud to be the only provider in Australia to offer the two most advanced and scientifically validated lie detection tools: the Polygraph and EyeDetect. Individually powerful, but together? Unmatched.
The Science Behind the Dual Approach: Successive Hurdles
In 1955, two pioneering scientists—Meehl & Rosen—proposed a groundbreaking concept called “successive hurdles.” Their theory was simple but profound:
If you administer two independent lie detection tests on the same issue, and the subject passes both, your confidence in the truthfulness of that outcome increases significantly.
This model only works if the two tests are independent—meaning they must measure entirely different human responses.
The Polygraph measures physiological changes like heart rate, respiration, blood pressure, and skin conductance—responses linked to the body’s stress and arousal systems.
EyeDetect, on the other hand, monitors changes in cognitive load, measuring involuntary eye behaviors, pupil dilation, and reading patterns—functions tied to the brain’s cognitive processing.
These two systems don’t overlap—they’re independent, which makes them the perfect pair for successive testing. When both tests agree on a result, the combined accuracy is significantly stronger than either test alone. In fact, research shows that this method pushes accuracy rates between 97% and 98% giving you greater confidence than ever before.
When Accuracy Is Everything
At Australian Polygraph Services, we use the latest computerised polygraph technology, administered by fully qualified professionals. We combine that with EyeDetect, developed by University of Utah researchers and backed by peer-reviewed science.
Our clients rely on this powerful combination in a wide range of cases:
- Relationship and family matters
- Employee theft or misconduct
- Legal disputes and private investigations
- False allegations and reputational damage
Whatever your situation, you’ll walk away with clarity, closure, and the confidence to make informed decisions.
