In On Bullshit, the philosopher Frankfurt (2005) defines bullshit as something that is designed to impress but that was constructed absent direct concern for the truth. This distinguishes bullshit from lying, which entails a deliberate manipulation and subversion of truth (as understood by the liar). There is little question that bullshit is a real and consequential phenomenon. Indeed, given the rise of communication technology and the associated increase in the availability of information from a variety of sources, both expert and otherwise, bullshit may be more pervasive than ever before. Despite these seemingly commonplace observations, we know of no psychological research on bullshit. Are people able to detect blatant bullshit? Who is most likely to fall prey to bullshit and why?
