It's nonsense to dismiss the IQ tests. When Davina interviewed Dr. Thomas Chamorro-Premuzic, on BB on the Couch, he said that Chanelle, Ziggy, then Sam and Amanda, had the highest IQ scores of the housemates, and all had similar scores. That was the case until the four new arrivals entered, although I don't know which of them had higher.
When Davina pointed out Chanelle's surprising score, saying she didn't use her intelligence, Dr. Chamorro-Premuzic told her that they were very long, state-of-the-art tests, and that the results never lie. Remember that he's a world expert on personality and IQ testing, so he knows what he's talking about. Channel 4, recently ran a propaganda documentary, condemning IQ testing, but it's telling that they wheeled out as supposed experts, Prof. Steve Jones and Prof. Steven Rose, neither of whom are remotely qualified to comment on IQ, and both are known for their liberal-Left poitics.
To clear up the confusion about the scales used in BB's tests, the one they use would need a score of 148 to qualify for MENSA. In the most commonly quoted scale, where 132 would qualify for MENSA, a score of about 119-120 would put you in the top 10 percent of the UK population. 67 percent are between 85-115, which is classed as the 'normal' range. An IQ of 70 is officially classed as borderline learning difficulties, although, as there are different ways of defining learning difficulties, many, such as Susan Boyle, are wrongly and unfairly labelled as having low intelligence.
