Sly Belief in Luck and the Revised Paranormal Belief Scale
Belief in Luck and the Revised Paranormal Belief Scale A Correlational Study PROBLEM Recent research has indicated that there is a conflation between the terms “superstition” and “luck” in the research literature (Lindeman & Svedholm, 2012; Sly & Kaiser, 2013) leaving the contemporary researcher with a need for a measurement scale to assess the specific belief in luck superstition when performing experiments involving luck-based superstitions. Wiseman and Watt (2004) indicate that many prior researchers have used the Paranormal Belief Scale (PBS; Tobacyk & Milford, 1983), or a newer version, the Revised Paranormal Belief Scale (R-PBS; Tobacyk, 2004) to assess belief in luck or superstition. However, Wiseman and Watt mention limitations of the Paranormal Belief Scales and suggest that future research into superstition and luck use a measurement scale that includes good-luck superstitions in addition to the bad-luck superstitions found in the Paranormal Belief Scales. There are a number of measurement scales used in research on superstition and luck (for a review see Lindeman & Svedholm, 2012). However, ambiguities and conflicting results concerning the dimensionality structure of some of these measures prompted Thompson and Prendergast (2013) to create a new scale, the Belief in Luck and Luckiness Scale (BILLS). While not addressing belief in good-luck superstitions specifically, as Wiseman and Watt (2004) suggested, Thompson and Prendergast propose that belief in luck encompasses both belief in good and bad luck on a bipolar continuum. Specifically, that a person either believes in luck (good and bad) or they do not. The BILLS has two subscales, which measures individuals’ belief in luck as well as their belief in personal luckiness, and has been shown to have “internal consistency reliability, convergent validity, and temporal stability” in the non-U.S. sample of participants used (Thompson & Prendergast, 2013, p. 505). The primary purpose of the current study was to explore correlations between items in the Belief in Luck and Luckiness Scale (Thompson & Prendergast, 2013) and the Revised Paranormal Belief Scale (R-PBS; Tobacyk, 2004), specifically the Superstition subscale of the R-PBS. We hypothesized that the Belief in Luck subscale of the BILLS would be positively correlated with the R-PBS, specifically the Superstition subscale, since both scales are supposed to measure irrational beliefs. However, we hypothesized that the Belief in Luckiness subscale of the BILLS would not be correlated with the Superstition subscale of the R-PBS, since Thompson and Prendergast found no correlation between Belief in Luck and Belief in Personal Luckiness. Specifically, Thompson and Prendergast found that some individuals who scored low on the Belief in Luck (irrational belief) scored high on Belief in Luckiness. To explain this, they hypothesized that these individuals “take luckiness straightforwardly to mean fortunateness.” (Thompson & Prendergast, 2013, p. 506). However, before we could explore the primary purpose of the current study, we first had to determine if the BILLS could reliably be used with undergraduate research subjects as most often found in U.S. research protocols. For reliable use with undergraduate research subjects in the U.S. we would expect to find comparable Cronbach’s alpha levels as Thompson and Prendergast (2013) found for both subscales of the BILLS, as well as concordant results when comparing correlations with the BILLS and Levenson’s (1981) Internality, Powerful Others, and Chance Scale (IPOCS). James S. Sly, Alexis Raushel, Jennifer Kemp, and Melissa Duncan Fallone Missouri State University METHOD and RESULTS In experiment 1 we administered the Belief in Luck and Luckiness Scale (Thompson & Prendergast, 2013), the Revised Paranormal Belief Scale (Tobacyk, 2004), and the Internality, Powerful Others, and Chance Scale (Levenson, 1981) to 198 undergraduate participants in a laboratory setting. In experiment 2 we administered the same three scales to 171 undergraduate participants via an online Qualtrics survey. To control for any order effect the three scales were presented in a counter-balanced order. In Thompson and Prendergast’s original study they found Belief in Luck alphas of .85 and .79 in their experiment 1 and 2, respectively. We found concordant results in both experiment 1 (lab) and 2 (online) of our studies for the Belief in Luck subscale of the BILLS (Thompson & Prendergast, 2013). Both delivery modalities resulted in very strong Cronbach’s alpha level of .90 and .89, respectively. Thompson and Prendergast also found very strong Cronbach’s alphas for their Belief in Personal Luckiness subscale with alphas of .88 and .89 in their experiments 1 and 2, respectively. We, on the other hand, found very low and unacceptable alphas in our two experiments, with only an α = .58 in our experiment 1 (lab) and a mere α = .37 in our experiment 2 (online). Moreover, where Thompson and Prendergast found no correlation between the two subscales of the BILLS (r = .07, p = .25 in experiment 1 and r = -.02, p = .72 in experiment 2), we did find significant positive correlations between the Belief in Luck and Belief in Personal Luckiness subscales, r = .25, p < .001, and r = .23, p < .001, in our experiment 1 and 2, respectively. Upon examination of the correlations between the Belief in Luck subscale of the BILLS with the Internality, Powerful Others, and Chance Scale (Levenson, 1981), we found concordant results with Thompson and Prendergast’s original studies (2013). Specifically, in experiment 1 (lab) we found that Belief in Luck was positively correlated with both the Powerful Others (r = .22, p < .001) and the Chance (r = .58, p < .001) subscales of Levenson’s IPOCS, while not being correlated with the Internality subscale (r = .04, n.s.). Moreover, we found similar results in our experiment 2 (online) with Belief in Luck being positively correlated with both the Powerful Others (r = .17, p < .05) and the Chance (r = .47, p < .001) subscales of Levenson’s IPOCS, while not being correlated with the Internality subscale (r = -.09, n.s.). However, Thompson and Prendergast also found significant positive correlations between their Belief in Personal Luckiness subscale and the Internality subscale of Levenson’s IPOCS, and significant negative correlations between the Powerful Others, and Chance subscales. We on the on other hand found only one significant correlation between the BILLS’ Belief in Personal Luckiness subscale and Levenson’s IPOCS across both of our experiments. Namely, in experiment 2 (online) we found Belief in Personal Luckiness to be positively correlated with Internality, r = .23, p < .001, which is consistent with the findings of Thompson and Prendergast. Finally, in both of our experiments we found that the Belief in Luck subscale of the BILLS (Thompson & Prendergast, 2013) was positively correlated with every subscale of the Revised Paranormal Belief subscale: Experiment 1 (lab): Traditional Religious Belief, r = .05, n.s.; PSI, r = .35, p < .001; Witchcraft, r = .27, p < .001; Superstition, r = .45, p < .001; Spiritualism, r = .42, p < .001; Extraordinary Life Forms, r = .25, p = .001; Precognition, r = .56, p < .001. In Experiment 2 (online): Traditional Religious Belief, r = .10, n.s.; PSI, r = .25, p < .001; Witchcraft, r = .15, n.s.;Superstition, r = .43, p < .001; Spiritualism, r = .33, p < .001; Extraordinary Life Forms, r = .27, p = .001; Precognition, r = .39, p < .001. Due to unacceptable Cronbach’s alpha levels in the Belief in Personal Luckiness subscale in our experiments we are unable to determine the accuracy of the correlations found between it and the subscales of the R-PBS, see Table 1 for the full list of correlations. Psychology Department CONCLUSIONS In two experiments, one in a lab setting and one administered online via a Qualtrics survey, we found that the Belief in Luck subscale of the BILLS (Thompson & Prendergast, 2013) produced similar internal reliability (Cronbach’s alpha levels) with our sample of U.S. undergraduates as Thompson and Prendergast’s original studies. These results indicate that the Belief in Luck subscale of the BILLS can be used as a valid measure of Belief in Luck when researchers have an undergraduate subject pool in the U.S. However, neither of our two experiments found concordant internal reliability (Cronbach’s alpha) levels for the Belief in Personal Luckiness subscale of the BILLS when compared to Thompson and Prendergast’s original studies. Future research should examine cultural issues that may affect the validity and reliability of the Belief in Personal Luckiness subscale. Likewise, both of our experiments found that high Belief in Luck is associated with poor personality functions as measured by Levenson’s (1981) Internality, Powerful Others, and Chance Scale and high degrees of various irrational beliefs as measured by the Revised Paranormal Belief Scale (Tobacyk, 2004). These findings indicate that the Belief in Luck subscale of the BILLS can reliably be used by contemporary researchers across the globe that might have a need for a measurement scale to assess the specific belief in luck superstition when performing experiments involving luck-based superstitions.
