The brain has a central CPU that is unconscious to most people. This is like the mainframe computer of the brain; inner self. The conscious mind is analogous to a PC-terminal, which can run its own programs, as well as access the mainframe CPU, using thought based command prompts. Intelligence tends to use the conscious mind more like a terminal than as a PC, taking advantage of the faster more powerful CPU. Some tasks require extensive data processing. If you dis these calculations on a PC sized computer, it can still work, but it will be slow. On the other hand, if you could use the PC as a terminal and transfer this task to the mainframe, it can speed through the calculations, and return an answer much faster. This faster turn around is what we call intelligence. A good analogy is connected to sports. Say you were a baseball player, who is at bat. The pitcher throws a fastball. You do not have time to consciously think or process all this information in a fraction of a second, with only the PC. You need the mainframe CPU to help do all the split second calculations for the needed muscle reflexes. The best players have terminal access and trust the mainframe problem solution. Say we change the scenario. Instead of a fastball, we need to solve an equation for homework. Since time is not a major concern, like hitting the fastball, we can use the PC to process the data, trying to remember the learned rules and logically applying them to solve the equation. Some students can zip through this homework and can get the answer really fast, since they use the terminal command lines instead. Sometimes, since the data crunching was done unconsciously, they may omit parts of the solution while still giving the right answer. This may be taboo, requiring that detach from the main CPU. They may be told to use only the PC, at its slower speed, so they can be more by the book. Sometimes exam will be a three hour test that you have one hour to complete. This poses a time processing problem for the ego PC. Those who can use the terminal command prompts, are able to take advantage of the mainframe CPU and may finish early. Although some gifted people are naturally wired as a conscious terminal, it is possible to develop this interface to the central CPU. There is a wall that was placed to prevent conscious access so the ego PC could evolve. Some people have natural permeability. The fine line between genius and insanity shifts one way when the mainframe processes too fast, and you don't have enough PC power to deal with the results; insanity. But if one can target the results, with conscious knowledge, we call it genius.
