Usually when we think of people who are very aware of their surroundings or very sensitive to the subtleties in all situations, we assume that it is because their brains are more advanced so they can see and understand things that the average person cannot. An example of such a person is Oscar Wilde. From his books, it is clear that he has a very different view of the world around him. He was way ahead of his time and understood things that we are only beginning to understand. He was very aware of how the world works, and so was advanced philosophically.
Could it be that such people are that way because parts of the brain that should function unconsciously did not develop fully or properly? And so they are forced to do things consciously,which makes them think differently and consider a wider spectrum of things than the average person. So it is actually a defect and not an enhancement of the brain that had resulted in this effect.
