Jeremy Kyle's attitude is an effort to make up for a profound lack of training or qualification. When he has finished his self-righteous and narcissistic rant, they wheel on Graeme Stanyer, who he refers to as 'the genius', by which he means 'the qualified', who offers a more reasonable and insightful approach (much like the professional style of Trisha Goddard).
Some of his efforts also appear to be a desperate bid to win over the audience's affections. He uses phrases like "It says Jeremy Kyle on the wall - my show, shut up!", then pauses for a moment to allow the audience to fill the awkward silence that follows with a cheer. Phrases like "reel your neck in" failed to get the reaction he expected, and only served to make him look uncomfortable and a little embarrassed as he awaited the reaction his face told us he so desperately wanted. He is more concerned with creating a persona for himself to ensure that he is retained as 'the talent' on the show, in fear of ITV making the sensible move and asking Graeme to host the show.
Before he states something 'controversial', he will always first of all say something like "I know a lot of people will disagree with me", or "I know some people won't like me saying this". This only serves to make the statement that follows appear more controversial than it actually is, or to make it appear that in the face of adversity he will still speak 'the truth'. This is intensely annoying.
Finally, the polygraph test. On the show it states that "practitioners claim it to be 96-97% effective", whilst scientific research suggests it to be around 60-70% effective, which is why it is not used as evidence in a court of law, and is not used by government agencies. If the bank valued your house at £250,000 and an independent evaluation valued it at £150,000, which would you believe? Of course the bank is trying to sell you a mortgage and it is in their best interests to have you believe your home is worth more than it actually is (and this does happen!!). So it is clear to see why polygraph examiners "claim" it to be around 96-97% effective - they wouldn't have a job if they told you it was actually 60-70% effective. This means that around four out of every ten questions asked will produce an incorrect reading.
There is much more I would like to have commented on, but don't have the time to write it.
