Our vision of the world is built upon the patterns of which we were either taught to see in it or have learned to do so by ourselves, whether said patterns are correct or not.
And the more we sink ourselves in the depths of our mental patterns that we project upon the External World, the harder it would be for us to see the world beyond said patterns.
There are no patterns in the World Beyond the Mind; only temporary order that is built upon the foundation of chaos and anarchy. Our world itself is a product of this principle.
What we do see in the External World are the illusionary patterns that we have taught to see in the world in order to get along with it. The laws of driving, the meaning of words, the authority of the norms - all of those aren’t really there in the world; they are in our minds and within our minds we plan our functioning in a world that is largely built upon said illusions - the illusions of societal conventions and paradigms.
Hence why when something that is surprisingly innovative may at first be seen as either weird or psychotic, because that thing does not correlate with the conventions and paradigms we have learned to see as the world itself.
Hence why it is hard to unlearn things after a long time we have been “programmed” to see the world through their colorized vision, because not only we learn to see them as the world, but we also attach our identity and our sense of order along with it.
And it can’t be, allegedly, that what we have been taught for most of our lives, if not our entire lives, is false, because if it is then much of what we believe we are is false as well. This is what makes the religious unprepared should they be told of a possible truth that contradicts what they have been loyally taught throughout their lives - it can’t be true, the religious mind believes, because it can’t be that the theory I have been taught about the ways of the world is false. Hence why it may be more difficult for the religious to keep an open mind and, let alone, be prepared to abandon beliefs that have been proved incorrect.
