polygraph ruine lives

[fippio]

   I'm against polygraph ; how many lives have been ruined by polygraph??  , many people become nerveous even if they say the truth.


And polygraph failed , MILITAR EXPERTS , SPIES , DETECTIVES...are trained to beat detector lie , Do you remember the case of FBI agent who beat detector lie during years ?  Polygraph  could not demonstrate nothing against him.

 accustomed people   to  use many tiomes thepolygraph can beat it in the short run , ok , one time two times you can lose against polygraph  but in the short run MANY PEOPLE CAN BEAT IT, No matter is there and profesional examinator.



But my question... how militar , spies are trained to beat polygraph?


I'm sure  that autosugestion , e.g.  if you have stolen in stores , u should think during one week before the polygraph test "i dont have stolen in stores"... i don't know if is effective . but professional know its because they change the question , so u should be prepared.

One thing its clear , people with cool head , can beat polygraph without a doubt .


Those pro-polygraph are capitalist people who only think in sell polygraph , and they are lying because say that polygraph its near to 100% effective , THIS IS REALLY A BIG LIE.
 
At the most 70% , no more .
