Abstract
Analyses of the Sleeping Beauty Problem are polarised between those advocating the “1/2 view” (“halfers”) and those endorsing the “1/3 view” (“thirders”). The disagreement concerns the evidential relevance of self-locating information. Unlike halfers, thirders regard self-locating information as evidentially relevant in the Sleeping Beauty Problem. In the present study, we systematically manipulate the kind of information available in different formulations of the Sleeping Beauty Problem. Our findings indicate that patterns of judgment on different formulations of the Sleeping Beauty Problem do not fit either the “1/2 view” or the “1/3 view.” Human reasoners tend to acknowledge self-locating evidence as relevant, but discount its weight significantly. Accordingly, self-locating information may trigger more cautious judgments of confirmation than familiar kinds of statistical evidence. We also discuss how these results can advance the debate by providing a more nuanced and empirically grounded account or explication of the evidential impact of self-locating information.

Notes
Here we have to acknowledge very helpful remarks from two reviewers.
Once properly specified, this hypothesis might find support from further investigation within our experimental paradigm. One could, in particular, consider how probability judgments differ in our Basic vs. Plus version (and/or some modification thereof) and make a quantitative comparison with the variation in the Plus vs. Marble version. Notice, however, that responses would have to lie on an interval scale for making this comparison. Given our elicitation procedure (with a 7-point scale), we deemed appropriate not to rely on this assumption in our analyses of data. (We thank the editor for raising this point.)
In fact, our notion of explicationism allows for significant nuances. Carnap (1950, p. 3) characterizes the task of explication as that of “transforming a given more or less inexact concept into an exact one, or, rather, in replacing the first by the second.” According to Carnap (1950, p. 7), an adequate explicatum should be similar to the explicandum in respecting prior usage — though “close similarity is not required” and “considerable differences are permitted.” It should be more exact than the explicandum. It should be fruitful in the sense of being “useful for the formulation of [...] empirical laws [or] logical theorems.” And last, the explicatum should be simple. Given its emphasis on the requirement of fruitfulness, Carnapian explication can be aptly described as aiming at “concept engineering” (Kitcher 2008). Kemeny & Oppenheim (1952, p. 308), on the other hand, distinguished their project from Carnap’s in these terms: “The commonest procedure of explication is to apply a trial and error method till one arrives at an ingenious guess, and then try to find intuitive reasons to justify the proposed explicatum. This procedure is clearly very dangerous: The intuition of the most honest and well-trained philosopher is likely at times to become a tool for grinding an axe. […] We feel that we must first put down clearly all that our intuition tells us about the explicandum, and then find the precise definitions that satisfy our intuitive requirements.” Given a stronger emphasis on the requirement of similarity, the goal of Oppenheimian explication is more one of concept clarification instead of concept engineering.
We thank an anonymous reviewer for prompting this clarification.
