Has anyone here ever lied on a polygraph and still passed?  How did you do it?

Let's be real, can anyone really reveal every embarrassing thing about their life in a poly?  I'm sure plenty of people have exaggerated on the number of times they did drugs, or got drunk, or went to strip clubs, etc.  What if you  know how to tell a lie and stick with that story throughout the process, to the point where you actually believe your own lie yourself? I refuse to believe that some machine can read my mind.  

Has anyone in here "not told the whole truth", were able to keep some incriminating things about themselves hidden, and still passed the poly-wolly?

'Has anyone in here "not told the whole truth", were able to keep some incriminating things about themselves hidden, and still passed the poly-wolly?'

First of all, you are assuming here that a polygraph machine works. They don't. So there is nothing valid about your question about passing/failing a test on a machine that is incapable of determining if a person is being truthful or not. You can't pass/fail a test on a machine that does not work.

To answer your question in its invalid context, yes, I passed a polygraph test years ago when I was hired by a grocery store. I kept concentrating on a brick wall with vines growing all over it. I kept describing the wall and the vines in my mind. With what I know now, I probably didn't need to 'try' to pass the thing. I even passed the loaded question 'Have you ever stolen anything?' by answering 'No'. However, no matter how I answered the questions, the machine didn't work and I therefore couldn't fail.

The only way one fails a polygraph test is through ignorance of the machine's capabilities. I once heard a black girl say that she had just failed a polygraph test because she became fearful that it would detect that she was lying when asked if she had stolen anything at here job. She blurted out 'nothing except that money that was found and put in the supervisor's desk'. She was a security guard and was immediately fired. If she had simply said 'no', the machine would probably have not registered anything. If it did then she could just deny it over and over again until the polygrapher gave up. Remember, you can't pass/fail a test on a machine that does not work.
