Christopher G. Ellison, Benjamin Dowd-Arrow, Amy M. Burdette, Pablo E. Gonzalez, Margaret S. Kelley, Paul Froese, "Peace through superior firepower: Belief in supernatural evil and attitudes toward gun policy in the United States", Social Science Research, Volume 99, 2021, https://doi.org/10.1016/j.ssresearch.2021.102595.
In order to measure the belief in supernatural evil, we will use the answers to three questions asked by the participants in the survey:
-
Whether the respondent believes in the devil.
-
Whether the respondent believes in hell.
-
Whether the respondent believes in demons.
You will investigate how the answers to these three questions can be combined to a single metric. Justify your approach.
Apart from the belief in supernatural evil metric, you will use several other variables to control your estimates.
