Solipsism in a “non falsifiable claim”. Which means it is a claim that cannot be disproven, but in no way it means it is plausible. One example of that is “Russel’s teapot hypothesis
”, which is a hypothesis saying that there is a teapot flying in orbit between Mars and Jupiter and that it is impossible to detect it using our current technology. If it’s impossible to detect it it means we cannot prove this hypothesis is right. But at the same time, if we don’t detect it it doesn’t mean the teapot isn’t there, because our instruments don’t work anyway.
Solipsism is very similar to this, you cannot prove it is right but you also cannot prove it is wrong. But does it mean this has any chance to be true? If you think it does, for consistency now you should perhaps also believe that Russel’s teapot exists. You can make infinite unfalsifiable claims, the only limit is your imagination.
Creationism can be formulated to be unfalsifiable. Young Earth creationists say that the world is 6000 years old, and you think you could prove this wrong by showing dinosaurs fossils that have been proven to be much older than that using radioactive decay. But some creationists will reply
that dinosaurs never existed and the fossils were planted by god 6000 years ago with some radioactive elements mimicking what millions years old life should have, just as a trick from god who wants to test our faith. If you point out that stars can be observed more than 6000 light years away (meaning that light was emitted more than 6000 years ago), some creationists will reply that the stars were created during genesis, and some light was also created already on the path between the stars and our eyes so that upon creation we should be able to see them already. So even though their claim is very unlikely, there is no way to prove them wrong.
Some skeptics made fun of this claim by making their own, saying that the world was created last thursday
(independent of the current date), everything was created at the same time, dinosaur fossils, buildings around us, everybody, and all our memories are fake and have been planted in our minds last thursday during creation. And you can still claim this is true next week, and that today’s memory was planted in your head next thursday, and it is impossible to prove this wrong. But this doesn’t mean it is any likely.
A colleague of mine told me that he thought the moon physically existed only when we looked at it. I think he was just messing with me and was proud to present a hypothesis that could not be disproven just to see me try and struggle with it. He wasn’t talking about “the image of the moon in our minds”, he was talking about the physical moon itself, that it disappeared everytime we didn’t look at it. But he is right, it cannot be disproven. But if this is true, it means that there is a kind of sensor that knows where everybody on the planet is looking, even through a mirror. And it knows when a camera is looking at the moon, or if someone in the future is going to look at the moon on the film. And when the moon disappears, something has to keep in memory the position of all atoms of the moon, to make them re-appear later on the trajectory of the moon and at the correct position and with the correct speed. And also when the moon disappears something needs to fake the moon’s gravity so that it doesn’t mess with the tides and with the trajectory of other space objects that we might be looking at. So it gets extremely complicated, and for no purpose at all other than making an unfalsifiable claim true, just for fun. So it is unfalsifiable, but at the same time extremely unlikely. You can also try to do the same with solipsism and think why there would be any chance solipsism could be true.
So if you think that the fact a hypothesis is unfalsifiable means it has any chance to be correct, if you believe in solipsism you should also believe in Russel’s teapot, in lastthursdayism, in the disappearing moon and in anything you can make up, like the theory there is an invisible imaginary animal in my garage that nobody can see including me. But I guess you don’t believe in these things, you only tend to believe in solipsism. And I guess you do so because something in solipsism is attracting you. And it’s a little paradoxical. Because I think you tend to believe in solipsism because you experienced DR, and you wonder if things could be flipped around, that you could have experienced reality (that solipsism is true), while the non-DR experience could be an illusion. So it’s your experience of DR (past or present) that makes you think that solipsism could be true. And it’s paradoxical because solipsism is all about doubting everything you experience, and yet you are attracted to solipsism because of an experience of DR. I don’t know if this helps though. Not that it is a good thing to doubt everything you experience, but just that solipsism is self-contradicting.
Perhaps you could imagine an unfalsifiable claim that goes the opposite way. Perhaps you are indeed imagining people’s minds and everything, but perhaps something is causing you to only imagine things that actually do exist around you and are real, and to imagine them
