The Text Suggests That Illusory Covariations Arise from the Fact

The text suggests that illusory covariations arise from the fact that participants

A) base their covariation estimates only on a small sample of the data that are available to them.
B) are generally dogmatic and make their judgments with little regard for the data.
C) do not know how to compute covariation, so they use an estimation strategy that is little better than guessing.
D) do not know how to make these judgments, so performance improves once participants gain some expertise.
