  1. Minimax and the value of information.Evan Sadler - 2015 - Theory and Decision 78 (4):575-586.
    In his discussion of minimax decision rules, Savage presents an example purporting to show that minimax applied to negative expected utility is an inadequate decision criterion for statistics; he suggests the application of a minimax regret rule instead. The crux of Savage’s objection is the possibility that a decision maker would choose to ignore even “extensive” information. More recently, Parmigiani has suggested that minimax regret suffers from the same flaw. He demonstrates the existence of “relevant” experiments that a minimax regret (...)

  • Can we make wise decisions to modify ourselves?Rhonda Martens - 2019 - Journal of Ethics and Emerging Technologies 29 (1):1-18.
    Much of the human enhancement literature focuses on the ethical, social, and political challenges we are likely to face in the future. I will focus instead on whether we can make decisions to modify ourselves that are known to be likely to satisfy our preferences. It seems plausible to suppose that, if a subject is deciding whether to select a reasonably safe and morally unproblematic enhancement, the decision will be an easy one. The subject will simply figure out her preferences (...)

  • Choice under complete uncertainty when outcome spaces are state dependent.Clemens Puppe & Karl H. Schlag - 2009 - Theory and Decision 66 (1):1-16.
    One central objection to the maximin payoff criterion is that it focuses on the state that yields the lowest payoffs regardless of how low these are. We allow different states to have different sets of possible outcomes and show that the original axioms of Milnor (1954) continue to characterize the maximin payoff criterion, provided that the sets of payoffs achievable across states overlap. If instead payoffs in some states are always lower than in all others then ignoring the “bad” states (...)

  • Weighted sets of probabilities and minimax weighted expected regret: a new approach for representing uncertainty and making decisions.Joseph Y. Halpern & Samantha Leung - 2015 - Theory and Decision 79 (3):415-450.
    We consider a setting where a decision maker’s uncertainty is represented by a set of probability measures, rather than a single measure. Measure-by-measure updating of such a set of measures upon acquiring new information is well known to suffer from problems. To deal with these problems, we propose using weighted sets of probabilities: a representation where each measure is associated with a weight, which denotes its significance. We describe a natural approach to updating in such a situation and a natural (...)
