Actually, the Omega situation is a perfect example. Someone facing the two boxes would like to increase his subjective probability that there is a million in the second box, and he is able to do this by deciding to take only the second box. If he decides to take both, on the other hand, he should decrease his credence in the presence of the million, even before opening the box.
In this case, the decision he’s leaning toward is evidence of the presence of $1M, by way of Omega’s observed reliability in predicting decisions of agents like him.
