Dogmatism correlates with fundamentalism, zealotry, and authoritarianism without being tautological

Evidence

However, these are the most direct “tautological” links I can find among the three measures. By and large, while they assess obviously related constructs, each scale goes off in its own direction, emphasizing different things. And all of the DOG items correlated significantly with Religious Fundamentalism and Zealot (and RWA) scores, in both samples.’ So the DOG Scale connected solidly with the criterion measures of Religious Fundamentalism and Zealot scores because fundamentalists and zealots tended to be dogmatic in all the ways assessed by the DOG scale, not just the obvious content-sharing ways.’ — Bob Altemeyer, The Authoritarian Specter, 2775

The balanced DOG Scale that measures it has pleasing levels of internal consistency. It has shown some encouraging ability to predict dogmatic behavior among students in several contexts, and it correlates rather solidly in expected ways with such things as right-wing authoritarianism, religious fundamentalism, and being a zealot, among university students and their parents. — Bob Altemeyer, The Authoritarian Specter, 2800
