Why did my test result in being inconclusive?

[poly27]

I recently took a polygraph exam. There were basically 10 questions that were relevant to my case.

8 of these questions I got a 100% telling the truth
2 of these questions I got a 98% telling the truth

So why does my results say "inconclusive"? Shouldn't they say passed?

Does anyone know why they would have given me an inconclusive instead of a pass?

This is what I have learned on this. After talking to the examiner later he explained everything.

The only way to get a pass is to get everything 100% correct. He also said that No matter how many you get correct they ignore all of those. And only make their pass/fail (really fail) on the ones you do not get 100%.

So for example you are asked 30 questions. 28 of those you get a 100% truthful and 2 of those questions you get a 90% change of being truthful. In their eyes there is a 20% change you are lieing about everything on the test. Which makes no sense to me. They add up all the percentile points you are off from every question and that is how they come up with their percentage of total lieing. Since there were 2 questions that were 10% off that gives you a 20% chance of lieing about everything.

And they are suppose to take you to another room and interrogate you on the 2 questions you didn't get 100% right. Until they find a way to get you to confess to something on them. Even if you were being truthful.

He even said himself that the system is really built around people who lie. And it is harder for truthful people to pass these tests. As they are not made for people to prove the truth. But an interrogation method to getting people to confess to a lie even if they are not really lieing.

It's very sad that it is like this. And this guy has been doing these tests on people for over 25 years.
