Do people understand determinism? The tracking problem for measuring free will beliefs
Samuel Murray, Elise M. Dykhuis, Thomas Nadelhoffer
Abstract
Experimental work on free will typically relies on using deterministic stimuli to elicit judgments of free will. We call this the Vignette-Judgment model. In this paper, we outline a problem with research based on this model. It seems that people either fail to respond to the deterministic aspects of vignettes when making judgments or that their understanding of determinism differs from researcher expectations. We provide some empirical evidence for a key assumption of the problem. In the end, we argue that people seem to lack facility with the concept of determinism, which calls into question the validity of experimental work operating under the Vignette-Judgment model. We also argue that alternative experimental paradigms are unlikely to elicit judgments that are philosophically relevant to questions about the metaphysics of free will.
