            Our brains create selective senses. The brain regularly chooses what it wants to hear or see and also fills in what it wants to hear or see. As a result, live in illusions. As part of the nervous system the senses physically report their perceptions to the brain. This data like other data in the nervous system is coded in electrical currents. If nothing is transmitted there is no perception. What the brain does with the data may be something else. This creates a large potential detrimental effect on our lives because of misinterpretation of things as they really are. On the other hand, the potential for bad decisions is increased when the decisions are based on incomplete or false data. Life can be more interesting, however because of the variation. For example, we may perceive different shades of colors. Hot pink could actually be light This phenomena could also be very useful in certain situations. For example, when I'm singing in competitions, it's nice to now know that if I do not quite correctly pronounce words in foreign languages, the judge’s brains will hopefully fill in what they think I was supposed to sing. The fact that people find so many ways to perceive things is perfect evidence of how the brain imposes its own construction on perceptions. This leads me to wonder how much of life is actually an illusion.
