One of the strongest theoretical predictions is that people with entrenched beliefs about an issue are less likely to change their mind when provided new information about that issue. Table \[tab:beliefchange\_means\_stddev\] shows the relationship between initial beliefs and extent of belief change. We defined people as having more entrenched initial beliefs if their response to the initial stance question was within 0.5 points of the two ends of the scale, i.e. (1.0-1.5) or (4.5-5.0), indicating an extreme initial view.

We tested whether people who were more entrenched initially showed less change than those who were initially more neutral. We conducted a 2 Initial Belief (Entrenched/Neutral) X 3 Argument Type ([ mono]{}/[emot]{}/[fact]{}) [anova]{}, with Belief Change as the dependent variable, and Initial Belief and Argument Type as between subjects factors.
