At the University of Goettingen in Germany they're pioneering technology that could greatly extend our control over our own brains. They're developing a means to turbo-charge our grey matter. The aim is to improve the volunteer's ability to subconsciously learn. The test itself is simple. When Leila sees a dot appear on the screen she has to tap a corresponding key on the keyboard. There is a pattern to when the dots appear. But it's impossible to detect. At least before the artificial stimulation of her brain begins.
What we want to do is to facilitate the excitability of her motor cortex. And in order to be able to do that we have to fix an electrode. I presume this is perfectly safe. I mean I'd be a bit nervous about having electricity shot through my brain. Well they're very weak currents.

Intelligence Theories X About IQ
The IQ test consists of many sections that seem unconnected. What does an entomologist study? There are sections on vocabulary and general knowledge. What's the capital of Jordan? Amman. What's the distance between London and Hong Kong in miles? I would suspect it's around a third of the way around the globe so about miles. A section on memory. Eight one seven five backwards. Five seven one eight.
And a section to test spatial ability. You're doing just fine. Wow that was tough. Do a lot of people get this one in two minutes? I can't see how that works. Common sense might tell us that we're good at some of these sections and bad at others. But that's not the case. On average if we're good at one of these sections we tend to be good at all of them. And from this comes the idea that intelligence is some kind of general all-round ability.

The correlations the statistical results that he reported remained identical to the third decimal. Well theoretically that sort of thing could happen. Also theoretically the sun might not rise tomorrow morning and that's probably a more probable event than what one would have had to have believed if one took Burt's number seriously. All of them remain identical to the third decimal place. Clearly something was drastically wrong. There's universal agreement among psychologists that Burt couldn't possibly have tested pairs of twins. That at least the last pairs must be figments of his imagination. I take perhaps an even more sceptical view of Burt. I think it's reasonable to suppose that he may never have laid eyes on a separated twin in his entire lifetime.
But Kamin was convinced that Burt was motivated only by his genuine belief in inherited intelligence. I don't think Burt thought of himself as a manipulator and misleader of the public. I think Burt had the intellectual audacity to think that he knew the truth prior to any actual investigation of the facts and therefore on account of noblesse oblige he was letting the rest of us get a handle on the truth by presenting us numbers that would help us to accept it. And he did us the courtesy of inventing the numbers for us.
Comprehensive proof of the part genetics play in intelligence still remained elusive but as the ' s got underway that didn't deter one man from adopting a radical new approach. In a rather sinister echo of Burt and Galton's theories Californian doctor Robert Graham reasoned that if there were intelligence genes to be had he could find a way of passing them on. In after Graham's death Horizon looked back at his extraordinary quest. My name is Robert Klark Graham and I had a dream. To single-handedly saved the human race one child at a time. Robert Graham believed that the gene pool was going downhill and that we needed to do something about that. He had this grandiose plan to remake all of humanity.
It had the air of James Bond movie meets Disney or something. Using the sperm of clever men I hope to create intelligent kids. He was this strange scientist that was trying to breed the super race. What we're doing is exploring the possibilities of genetics. I was accused of being a racist and a Nazi. I can't say that I know much about Hitler or his vision. Yet my sperm bank was operational for nearly years. Despite tremendous controversy I was responsible for the creation of over children.

Intelligence Theories IV
And he certainly tried to follow in his footsteps. Oh no. Do you read classics? I want to be a scientist. Burt was particularly drawn to one of Galton's ideas. In Galton had coined the term eugenics meaning good birth. He believed that people of high rank had greater intelligence and should be encouraged to marry and have children to preserve these traits while the poor be strongly discouraged from breeding. Burt adopted this idea with enthusiasm. For example Burt has written out on his hand "The problem of the very poor. "They must be segregated prevented from reproducing their own kind".
This is the kind of atmosphere obviously to which he was exposed. Working in the s Burt was determined to prove intelligence was inherited. He brought together more evidence for the inheritance of intelligence than any other person had done at that time. His papers were more impressive in terms of the number of different kinds of kinships on which heritables had been estimated. The fine grain detail in which the analyses were carried out. And so on. Burt introduced the IQ test as a way of measuring schoolchildren's intelligence. He was also to influence the introduction of the Plus test which was to become a key decider of a child's academic future. By every child's intelligence was tested. In order to study the inherited element of intelligence
Burt looked for subjects that were the same in every way except the environment they were brought up in. Identical twins who had been separated at birth. So now if you can find when they are old enough to be IQ tested a fair number of pairs of such twins you can give them all IQ tests and if their measured IQs resemble one another that must be due to the only thing they have in common namely their identical genetic make-up. It cannot be due to their environment in theory because they don't have that in common. Burt announced his findings with a great flourish stating that he had found genetics were responsible for % of his subjects' IQ. In the crucial matter of separated monozygotic twins and the measurement of the genetic heritability of intelligence over the years we have been fortunate enough to steadily increase our sample size to the point where our data based on pairs of twins is some % greater than that of its closest rival. Burt's research was highly respected and in he became the first British psychologist to be knighted for his contributions to psychological testing. But his ideas on eugenics had rather lost their appeal.
Adolf Hitler adopted this philosophy to murder thousands of people he labelled mentally defective. The scientific community began to distance itself from the idea of engineering society according to intelligence. Burt continued to defend his ideas but it was only after his death in that scientists including Professor Leon Kamin scrutinised his results and came to some uneasy conclusions. As the sample size increased progressively in successive papers one noted an absolutely incredible thing.
