“Dogmatism and Domination: A Simulation Study”
ZOOM ID: 875 4056 2860
Charles Lassiter is an associate professor of philosophy at Gonzaga University. His research focuses on issues at the intersection of mind and culture, including the metaphysics of mental powers and the epistemology of expertise. His current modeling work develops the concept ‘probability of belief change’ and looks at how that can contribute to explanations of polarization and convergence.
Dogmatists are individuals who will not change their opinions on a given topic. Other work has illustrated that N dogmatists with different beliefs will cause clustering of a population into N groups. This study looks at the effects of the volume of dogmatists for opinion dynamics in a population. The simulations suggest that small increases in the proportion of dogmatists in some group (relative to the number of dogmatists in a competing group) has surprising effects but that the effects decrease as the proportion increases. I conclude with some observations on varieties of dogmatism and the persistence of echo chambers.
