its also all mental, when they ask u a question, in ur mind try to convince urself that they asked u somthing else with the answer u wont be lieing to. example if they ask have u used steroids in the past year. in ur head keep convincing urself if they asked u if ur from mars or ur dads elivis or somshit like that, and say no. this only works for the strong in mind, if ur weak minded go snort some coke or inject it or do something that will make ur heart go nuts. and keep a tack in ur shoe. if u combine all three things i just said the machine will start to smoke cause of confusion ull pass. they beat those tests like theres no tomorrow. just takes practice. measure ur heart rate at home and have ur friend as u questions etc. and record it ur heart shouldnt speed up cause if it does it means ur lieing. also dont jump into answers, it supposedly takes the mind twice as much time to find somthing wrong then it is when its right. so if u say no to the steroid question ur mind should take longer to process it cause it double checks and then answers. most liers will just blurt it out right off the back, and also dont look up ALWAYS keep eye contact on an inatimate object. like the person thats asking u his nose or lips or chin or somthing. with all those things in mind ull be sailing.!! good luck bro!
Omega44, not to sound like an ass. But you don't know what you're talking about. You will not, I repeat, you will not beat a lie detector with that approach. Do a little research before you come giving answers. Like take one. I've taken them and beaten them.
First off, their are things that a polygraph test looks for, like:
Change in blood pressure.
Change in respiration.
Change in heart rate.
Change in Perspiration.
Their are two types of polygraph tests.
One that asks you the questions before you actually take the test. And then again during the test.
And one that asks you the questions during the test for the first time.
The way you beat the tests is by being able to keep all the above mentioned changes in check during each question.
Or, by sending out the same signal during every question so that every response has the same reading.
What to do and take:
For change in blood pressure, repiration, and heart rate, you need to take some sort of relaxer like valium. That will get you very relaxed.
For change in Perspiration you need to put some drysol on your finger tips.
Now what you want to do is put a thumb tack underneath your big toe. When a question is asked and you answer. Press on your big toe and that will send a shock of pain through your system. DO THAT FOR EVERY QUESTION. The readings for all the questions and answers will be the same. Therefore they will not be able to tell you were lying. They will also not be able to tell you were telling the truth. But an inconclusive reading is better than a reading of guilt.
Lie detectors can be beaten. You just need to know how to beat them. And telling yourself over and over again something is the truth, is not going to do it. I don't care how "strong minded" you are. You're going to get caught.
