Takeaway
Although working memory may be a predictor of individual differences in belief bias, strategy use may be a better predictor and may be the cause of different patterns of response times on conflict and non-conflict problems.
Why this matters
A common explanation for individual differences in the ability to draw rule-based inferencedepends on working memory capacity but strategy use may be an important determinant of the way people make inferences when rule-based and belief-based cues are both present.
