It's entirely possible that they weren't testing "bullshit-sensitivity," but some underlying language skills, IQ, or even something like creativity (required to give the sentences have meaning). I don't think that they test has sufficient evidence that it measures what they claim it measures. Second, donation experience did not have a statistically significant relationship with "bullshit sensitivity," which is kind of a bad smell. As for prior plausibility, the authors admit "previous theory and research does not give us strong reasons for predicting a direct relation between reactions to bullshit and prosocial behavior." The study also lacked a control group.
