There is a feeling that I had a long time ago that I could not accept some new things, and I was not willing or afraid to try them. Human beings have always been exploring, and they grow up a little bit in the confusion and ignorance at birth, and in the intersections of social groups, countries, nations, and individuals, all of them are giving him knowledge and information flow. It is also the things that we come into contact with in our early childhood that build up the "cage" that is exclusive to us and that determines our position and our prejudices. This prevents us from being open to new knowledge and makes us unconsciously selective in the information we receive. It can also be described as arrogance and prejudice.
