The subject of intelligence has occupied psychologists since the beginning of psychology about a hundred years ago, and the way of meassuring the intelligence quotient of a person through the so-called IQ test has been a misguiding, but accepted, way of establishing quality of life. But now the brain research might be able to draw a new picture of intelligence, a picture that opens up to a new way of seing intelligence, as qualities not based on verbal language and the logic-mathematic.

To start with the purely anatomical view on intelligence, it is sure to say that the size of the brain is a relevant factor, but it is not just a matter of the amount of neurons. The complexity of the connections between these neurons and the size of the brain in relation to the rest of the body must be taken in consideration as well. And here we can see that the species we consider as the most intelligent, such as the human being, the higher primates and the dolphin, have brains of a size up to six times the ones of most of the rest of the living mammals. But that is not all that is taken in consideration, as itin a much higher degree is a matter of the cerebral cortex and its size and shape. The cortex, the 3 mm thick layer of gray matter, is where all higher thinking and understanding takes place. In the development of the higher species, the cortex began taking a new shape, as it started to expand without having to aquire a larger scull and a larger body, that would only remove the advantage of a larger brain as it would need the extra capacity to control the larger corpus. The way this was solved, was by letting the cortex fold inside the scull, and actually expand the surface of the brain without expanding the scull. Therefore the largest brain potential is found among the higher species mentioned above, even though the human head actually has grown, and most likely will keep expanding into the next evolutionary step, but has still been able to keep up with the expansion to create an even more folded brain. We must remember, though, that are only talking about potential intelligence, as intelligence is conditioned by the influences coming from the outside as well.
This leads to the way the intelligence is developed, the way our 70 % of the, at birth, unused potential is shaped by the sociological conditions. At the moment the intelligence tests, and by that our education systems, are based on the ability to understand and use the verbal language and the logics of mathematic problems, not much room was left for what was outside of these frames. But now scientists have come up with a new way viewing intelligence, a much more open model. This model, called the multiple intelligence, claims that the human brain consists of not one but seven modules of intelligence: The intelligence of verbal language, intelligence of music, intelligence of logic mathematics, intelligence relating to space, intelligence of the bodily- kinetic and the intelligences of the personal mind and the personal surroundings. All these syven modules, that together gives the structure of human cognition and thinking, seems to be at the same footing at birth, but can seperately, from sociological influences, be either ignored or further developed. This means that we all in basics contain the same intellectual potential, that the, at the moment, suppressed non-verbal and creative intelligences ought to be revised, and valuated as important as the linguistic sides of the human mind.
