["\nConservatives—both political and religious—are more likely than liberals to support laws regulating traditional or religious morality. The current study applies a moral psychological framework to argue that the association between conservatism and moral regulation law support can be explained in part by binding morality, or a moral orientation that privileges group needs above individual needs and includes concerns about absolutism, collectivism, and purity. Binding morality may directly promote support for moral regulation laws, which enforce traditional rules, discourage deviance, and require adherence to customs regarding bodily and spiritual purity. Binding morality may also indirectly promote support for moral regulation laws by motivating perceptions that “immoral” behaviors are harmful to innocent victims. I test these hypotheses using three analytic samples drawn from the General Social Survey (N = 3669, 7120, 369). Results show that, as expected, binding morality (especially purity) mediates the effects of political and religious conservatism on laws regulating pornography, marijuana, abortion, and euthanasia. Additional analyses exploring views about pornography show that binding morality (especially collectivism) is associated with perceptions of immorality as harmful, which in turn is associated with support for regulation.\n", "Law & Society Review, Volume 54, Issue 3, Page 680-719, September 2020.
