The theory of possibilities

I've got quite interested in the future prediction these days, one nice idea by Russian writer Sergey Borisovich Pereslegin is that we should build the future based on the theory of possibilities rather than the theory of probabilities. This is a very deep idea actually.

The probability theory is very common these days and everyone is applying Bayes things here and there. But the problem with probability theory it can only predict probable thing which are known before or have been observed before.

The theory of possibilities can discover new unknown things.

This is quite a researched subject surprisingly, for example one can check
