The free will inventory: Measuring beliefs about agency and responsibility
Open accessAbstract
In this paper, we present the results of the construction and validation of a new psychometric tool for measuring beliefs about free will and related concepts: The Free Will Inventory (FWI). In its final form, FWI is a 29-item instrument with two parts. Part 1 consists of three 5-item subscales designed to measure strength of belief in free will, determinism, and dualism. Part 2 consists of a series of fourteen statements designed to further explore the complex network of people's associated beliefs and attitudes about free will, determinism, choice, the soul, predictability, responsibility, and punishment. Having presented the construction and validation of FWI, we discuss several ways that it could be used in future research, highlight some as yet unanswered questions that are ripe for interdisciplinary investigation, and encourage researchers to join us in our efforts to answer these questions.

Free will beliefs were measured using the Free Will Inventory (FWI) and the Free Will and Determinism (FWD) personal agency subscale.
“For the extension, free will beliefs were measured before the replication using two free will belief subscales: Free Will Inventory (FWI) (Nadelhoffer et al., 2014) (5 items; 1 = Strongly disagree, 7 = Strongly agree; = 0.91) and Free Will and Determinism (FWD) personal agency subscale (Rakos et al., 2008) (4 items; 1 = Not true at all, 5 = Almost always true; = 0.92).”

“FWD was chosen as it focuses specifically on free will beliefs in the self, which we thought might differ from the more generalized FWI scale.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
