Unfortunately I recently come to conclusion that this argument against dust theory is flawed.

Because thoughts of dust mind are random and are not causally dependent from his experiences. So he in 50 per cent cases will think that his environment is OK and in 50 per cent that it is random and strange. While his environment is 99.99 per cent cases is strange.

The best example here is our thoughts during dreams. Sometimes during a dream we think that the dream landscape is normal and sometimes we think that it is bizarre. But in the morning we understand that it was bizarre in most cases! This happens because our mind is not able to calculate bizzareness during the dream.

(I don't claim that we are Boltzmann brains after all, but we have to find another proof)

I don't see any reason to think that the thoughts of a dust mind would be random in that particular way, namely thinking that the world is ok in 50% of the cases.

If dust mind has random experiences he should also has random thoughts. Most dust minds will not interested in the question about orderness of their reality. But in the small subset of those who interested, the answers will be random.

And if you see mess in my room now you may think that it is rather random )))

A dust mind isn't the same as a Boltzmann brain. A dust mind would be an interpretation of random facts as a mind -- e.g. you could interpret the movement of dust particles on the road outside as a mind, if you give a sufficiently complicated interpretation. But you may be right that we should expect that mind to have random experiences and random thoughts. I am just saying that I don't see why randomness would necessarily lead to a 50/50 probability between those two -- it isn't clear that they are equal regions of the probability space. It could be like saying that rolling two dice randomly should give you a 12 half the time.

Yes they are not the same by their origin, but (probably) the same in distribution of their possible experiences.

In the dice example only in 1 case of 12 the "environment" will be not random, but the mind who looks on dices is also has random thoughts about dices, depending not form the dices results, but form a random coin.

So in 6 cases he will think that they a random (and they random), in 5 cases that they not-random, but they are random and in 1 case that they are not random and they are not random.

In short we can't believe our thought process in determining randomness of enivronment, because if the dust mind our thought process is full of errors.

But I still think that I am not random dust mind, and I use other lines of thoughts to prove it.

First is that any random mind is equal to some real mind (if any exist) and by process similar to quantum (big world) immortality will be immediately "copied" into real one.

The second is that there is lines of sequences in the space of all possible mind, which connect similar mind-states and these lines tend to converge to more stable ones. I suggested this idea last year to a guy here on LW who was really afraid that he is dust-mind and he was satisfied.

Some other ideas exisе about it, I should make a map about BB and dust minds. ))
