Filling in missing information.
Mistakes of imagination (future) are made up of my mistaken memory (past) and my mistaken perception (present). My memory is "filled in" with perceptions that are experienced after an event and this happens quickly and unconsciously. "Filling in" with extraneous data after the fact is the mistake my memory and perception do. I don’t take into consideration all the "filling in" that I've done when I imagine how I'll feel and what I expect to experience in the future. This "filling in" happens so fast and is so unconscious that I'm fooled by it completely. I see things that are not there and know things that really didn't happen. I imagine a future that will not come to be. Not only am I "filling in" details I am also "leaving out” details missing a world of possibilities.
If I can acknowledge this in me, then others must be doing it too. I have to give then the slack to be who they are just as I hope they would give me the same understanding for my mistakes of imagination. I want understanding where appropriate and I want to be called out when appropriate.
The microcosm of the quantum world and the unconscious are not part of my active experience and therefore are less interesting than those things that are part of my active experience. Things like focus, biases, common fallacies, virtues, ethics, and life trajectories. To me the question of the meaning of life and questions like this are uninteresting.
