A hypothesis that begins with a large prior advantage and runs at roughly the same speed in accumulating supporting evidence wins by a large margin in posterior probability

Notice that the general strategy of the particular version of the low priors argument discussed above is to find an alternative to omni-theism that is much less specific than omni-theism (and partly for that reason much more probable intrinsically), while at the same time having enough content of the right sort to fit the totality of the relevant data at least as well as theism does. In other words, the goal is to find a runner like source physicalism that begins the race with a large head start
