Have you heard of the famous Monte Hall problem in statistics? It’s freaky. And I believe it offers the best evidence that our reality is subjective.
The set up is this. Game show host Monte Hall offers you three doors. One has a car behind it, which will be your prize if you guess that door. The other two doors have goats. In other words, you have a 1/3 chance of getting the car.
You pick a door, but before it is opened to reveal what is behind it, Monte opens one of the doors you did NOT choose, which he knows has a goat behind it. And he asks if you want to stick with your first choice or move to the other closed door. One of those two doors has a car behind it. Monte knows which one but you don’t.
The trick here is that most people assume it makes no difference if they stick with their original choice or move to the other door. They believe the odds are 50% either way, since there are only two choices and you don’t know anything about either choice. But mathematicians say that is wrong. You substantially increase your odds by switching doors.
That is interesting enough on its own. (I’ll give a link later that explains the math of it.) But here is the freaky part. You only improve your odds by switching doors if Monte Hall knows what is behind each door. If he simply got lucky and opened a door with a goat behind it, your odds are unchanged. In other words, your odds are changed by Monte’s knowledge, and your knowledge that Monte has that knowledge.
If reality were objective, statistics wouldn’t be influenced by knowledge. That means your world is either partly created by your mind, or you are a hologram created by some other mind, and there are a few bugs in the software.
Here’s a link to more than you want to know about the Monte Hall problem.
You see the same sort of thing happen in the classic double-slit experiment in physics. The result of the experiment changes if the observer has additional information about what slit a photon passes through. Again, knowledge changes the real world. That can’t happen in the world you imagine you are living in. It has to be a bug in the hologram program. At the very least it shows that your reality is subjective.
Here’s more on the double-slit experiment.
