Imagine the whole world as if you were looking at it from outer space. Out of the entire globe how much have you actually seen? Maybe 1% of the entire world you have seen. This is the same for every situation that your are in. You do not see the whole picture. You only see a small piece of the world and we think we know everything. Our senses can only take in a limited amount of information and out of that limited information our brain filters what it thinks is important and discards the rest of the information. Everyone has a different filter and bias based on their own experiences. Everyone focuses on different things and discards different things. Everyone is different but who is right?
