You can't, because it's a chaotic system. If you eschew computers and "simulate" the stock market by building an entire world with humans and an economy you would get a stock market that functions similarly to the original but not the same as the original, so it would be almost useless for predicting a particular stock movement. A computer simulation can't be expected to be better than a simulation with real humans living in a real world. In other words, you would be simulating *a* stock market, not *the* stock market. > The brain has the same issue - you can't tell what it is going to do from > the outside, because the behavior on the outside is often driven by the > story going on the inside - which cannot be known unless you too are on the > inside. But that's the case for everything. Its behaviour is driven by what is going on on the inside as well as what's going on on the outside. -- Stathis Papaioannou -- Stathis Papaioannou -- You received this message because you are subscribed to the Google Groups "Everything List" group.
