Puts a whole new light on job hunting. Polygraphs are almost non exixtent for work in the UK, I`m sure someone could say thats its an infringement of their human rights and win. I personally took several tests in the USA (Washington DC and Houston Texas) and had no trouble. Since these tests are not admissable in court,Why have them? They are not 100% accurate and the employer is relying on the people conducting the tests. As you can see from Chips article, you can change the results as you go along. In these circumstances "Honesty" is not always the best policy.
