There is some truth in the standard paradigm, in that there is structure to our opinions and worldviews. There is an objective world.
We do share reality with one another, but the problems with the standard paradigm are enough to make a difference and enough to explain why we really do live in our own world.
So where does it falter? Well, first of all, our psychology is wildly different from other people. Things like our worldviews, our opinions, our desires, our fears, our memories, our life history, our goals, our ideals, our levels of development, our age. These are all wildly different from other people, even people in our family.
Have you ever noticed how different you are from even the closest people to you in your family? That should show you that you are wildly different psychologically from other people.
The other problem with the standard paradigm is that, fine, there might be an objective reality, but we don’t experience all of it, not even close to all of it.
Each of us experiences a very limited part of objective reality. So our input or our material is entirely unique. In that sense, each of our objective realities is unique.
There is an objective reality, yes, and it contains everything that we could possibly experience with our senses. Right. But none of us has ever experienced all there is to experience, so none of us has ever experienced objective reality.

What’s more, our experiences are all very different: we all have our own unique set. And so our own personal objective reality is very unique.
We all do different things. We go to different places. We have different friends. We all receive different kinds of information from the books we read, from the podcasts we listen to, from music, from TV and Netflix, from the classes we go to, from our work environment, and on and on.
And all of this defines our objective reality. It defines the unique world that we live in. It is part of our unique world.
I’m not only talking about our inner world, although that certainly has an impact. I’m saying that the raw information we’re receiving from objective reality is very personalized to us.
And so, right, objective reality may exist, but we never experience it. None of us know what that is exactly, because all of our objective realities are different.
We might know what it means to say there is an objective reality and we try to talk about this objective reality, but we still can’t step out of our subjectivity. We can’t step out of our personal experience of life, all the input we receive and the little bubble we live in.
And since our idea of objective reality is very different from the next person’s, we can’t ever really talk about objective reality.
