One Study Found That If Participants Were Told a New

One study found that if participants were told a new fact about robins, they would also believe that the new fact was true of ducks. However, if told a new fact about ducks, participants would not extrapolate this information to robins. This suggests that

A) participants treat each category member independently (on a case-by-case basis) when applying new beliefs.
B) participants are willing to make inferences from a typical case within a category to the whole category but not vice versa.
C) new knowledge about a member of a category is unstable, leading to a change in a person's belief system only on rare occasions.
D) beliefs within a theory are less likely to affect typical category members than atypical ones.
