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.

It is a common assumption among both philosophers and psychologists that having accurate beliefs about ourselves and the world around us is always the epistemic gold standard. However, there is gathering data from social psychology that suggest that illusions are quite prevalent in our everyday thinking and that some of these illusions may even be conducive to our overall well being. In this paper, we explore the relevance of these so-called 'positive illusions' to the free will debate. More specifically, we use the literature on positive illusions as a springboard for examining Saul Smilansky 's so-called 'free will illusionism '. At the end of the day, we will use data from both social and developmental psychology concerning perceived control to try to show that his view is on shaky empirical footing
