Moral Foundations Theory & Nonproliferation

Building on the foundational works by Nina Tannenwald and T.V. Paul on the taboo and non-use of nuclear weapons, respectively, as well as recent research by Daryl Press, Scott Sagan, and Benjamin Valentino that showed the aversion to nuclear use is lower than previously believed, Dr. Smetana and his colleagues set out to determine the kinds of psychological profiles that people who support the use of nuclear or chemical weapons might have. Using the five basic blocks of morality as outlined in the Moral Foundations Theory (MFT)—care/harm; fairness/cheating; loyalty/betrayal; authority/subversion; and sanctity/degradation—they designed two experimental studies. They presented a sample group with three scenarios—nuclear-weapon use, chemical-weapon use, and a conventional strike—and asked if they approved of each use. Their findings show individuals’ “moral foundations” determine how they feel about such use, and that, while these moral foundations can’t be changed, by reframing the question in ways that resonate with various psychological foundations, disarmament advocates can convince a broader audience of the benefits of disarmament.
