Even randomness can be quantified.

Aye I see what you mean, so if it says "you will eat it" you think "well **** you, I won't do it!" and it's wrong, and vice versa if it says you won't.

I guess plausibly it could be good enough to predict your reaction to what it says you will do, but yeah you're right that wouldn't really avoid the problem. I guess the problem is the prediction will need to factor into the result, but the result would change the prediction.

That doesn't really change the problem of free will or determinism though, I guess. It merely says expressing predictions can be self-defeating. It could still accurately predict what you'd do, it just possibly couldn't tell you truthfully what it is.

What about weather then? If I, as a living human being am, in fact, only a very complex unit of organic matter with only an illusion of free will, when actually my deeds can be predicted, could we predict weather for a year on?
If I, not containing anything supernatural, can not hear the prediction for it to be true, why wouldn't weather react to us doing it? For example, the breath of someone saying this prediction, the wind of someone's fingers that would be created when typing that forecast on the computer...
Could the original forecast itself have predicted this breath and wind and of course the reaction of all the people on earth to that forecast? Wouldn't we, or the weather man be aware, that the slightest changes in the atmosphere can alter the weather a year on from now? The weather man being aware of this, if the analogy from the cookie is applied, wouldn't the weather man hearing the prediction cause the prediction to be actually false?

How about weather forecast for unpopulated planets? Do humans really make a difference?

The act of making a prediction can the results, but it needn't always been in the same way as the example of telling someone what they're going to do.

The act of predicting, assuming it causally affects the outcome (which as you say, is pretty much certain in that the effects of our actions can be a lot wider ranging that we might think), can still be included within the prediction. Even in predicting making a decision, a supercomputer might know that telling you you will meet someone might actually case you to meet them. It needn't always contradict its truth to give a prediction, just it sometimes can do.

The act of predicting can either be insignificant enough causally (due to distance or simply being very minor) to not affect the prediction, or could actually bring about the prediction. Of course, to say it is in principle predictable doesn't mean anyone or anything in practice ever could collect all the data and know the laws well enough to do it, especially on a global scale, or that they would have to actually perform the action of making that prediction for it to be true.


In any case, the most important fact really is that in principle if all facts about your personality and a particular situation were known, it could in principle be known exactly what you'd do.

Yeah, I guess this has to be taken more theoretically than trying to apply it to an actual example.

I don't really believe in random.. I believe it's just a matter of perspective, but what appears "random" is really such a complex order that we can't perceive its order. Of course you could also say that everything is chaos, and what appears to have order is just an illusion. I also believe fate and free will exist simultaneously, in a paradoxical way.

I'm sure you have some kind of reason for thinking this, but I can barely understand what you mean, let alone why you'd think it.
