The Jeremy Kyle show constantly uses so called 'lie detector tests'
Calling it a lie-detector suggests that
a polygraph machine can detect lies. The device actually measures nervous
excitement. It operates on the premise that if a person is telling the truth
they will remain calm.
If fact the polygraph has been shown to have a 50%
chance of detecting the truth ie. it is entirely random see Lykken, D. (1984).
Polygraphic interrogation. Nature, 307, 681-684
the National Research
Council an organization of scientists conducted a systematic evaluation and concluded that
the test is lacking in scientific validity
Yet despite this being easily
available public knowledge - Jeremy Kyle uses polygraph tests to humiliate
people, to accuse them of lying to get them to end relationships, to stay in
unsuitable relationship. This is surely a breach of the relevant codes
The programme ought to be taken off air.
