How knowledge alters perspective
Finally, amongst the strongest regulators of perception is the extent to which our limited knowledge about a particular subject or experience dictates our beliefs about the experience. Knowledge is the ultimate stepladder, with an infinite number of rungs to climb, and a multitude of subjects to grow our knowledge in. Imagine a different latter for every different subject in the world, and imagine each person on their own particular rung in each particular subject. In some areas one person has climbed to rung 53, another is stuck at 22, while another hasn't even stepped on the ladder yet in this particular subject matter. The world is ruled by this tiered hierarchy of knowledge. Everybody is on their own levels of knowledge about any particular topic, thereby distorting our understanding of that topic from person to person, thus changing the very way in which they perceive it. Those highest on the ladders can see much farther and broader (the "bigger picture") in their subject than those who have yet to climb on.
People will overpay for a particular item because they lack the knowledge that the store two doors down is selling it for half price. One man sells an old painting at a garage sale for a couple of bucks. The man who bought it proceeds to turn around and sell the same painting, which happens to have been done by a famous artist, for $250,000. Each man's perception of the painting’s value differed according to their knowledge of it. And on a daily basis all around the world, people make critical mistakes and are unnecessarily provoked into strong negative emotions because they lack crucial information on a particular subject. In every aspect of our lives, what we know to be true is dictated by what we know.
