This paper discusses methodological issues of two recent experiments conducted by Christopher Bartel, and Elzė S. Mikalonytė and Vilius Dranseika, respectively, about the repeatability and individuation of musical works. I argue, first, that the reliability of their results about people’s intuitions in our everyday musical practices can be questioned due to the use of descriptions instead of musical stimuli of the works and performances involved in the cases tested. This procedure is prone to place participants in an epistemic situation in (...) which their mental capacities for their everyday judgments are not deployed and makes their judgments more vulnerable to the problem of “filling in”. I provide empirical data of an experiment that implements musical stimuli, obtaining large effect sizes regarding the results obtained by Bartel, Mikalonytė and Dranseika. In addition, I argue that the results of three scenarios of the experiment conducted by Mikalonytė and Dranseika are suspicious of being influenced by presentation effects that favor the contextualist intuition that the composer is a relevant parameter in work-individuation. Formal and superficial aspects of the description of their cases would cause these effects. I supply empirical data of an experiment that neutralizes those effects, obtaining moderate and large effect sizes regarding the results of Mikalonytė and Dranseika. (shrink)
