The classic Dogmatism Scale failed because of weak consistency and yea-saying bias

Evidence

Rokeach’s elaborate conceptualization failed to be represented on the Dogmatism Scale, which had almost minimal levels of internal consistency, and then shot itself in the foot (heart and head) by failing to control for yea-saying. Thus the primary measure had virtually no construct validity, and the die was cast. — Bob Altemeyer, The Authoritarian Specter, 2799 (#expands, via linked claim)
