> Since the outcome would provide information in the negative, it also does in the positive. No, this doesn't follow. The two cases are not symmetric. Ruling out a phenomenon (if we assume for the sake of argument that a "negative" simulation result can actually do this--in reality things are quite a bit more complex, the simulation was not run as a binary yes/no test of a "phenomenon") rules it out. But showing that a phenomenon is possible doesn't tell you anything useful about whether it actually happens.
