One of the main criticisms has been that the work is overly simplistic[19] and too narrow:[22] that the book does not acknowledge the many dynamic factors involved in communication, or the dynamic nature of truth.[19] This criticism also explains that the work is limited in its analysis of other motives and forms of bullshit aside from one stemming from a lack of concern for the truth.[22] One critic notes that the book does not mention, or dismisses, the audience's ability to detect bullshit:[18] that Frankfurt's explanation of bullshit presents a narrative where bullshit goes unnoticed or is easily excusable by its audience.[23] Another critic points to the book's failure to rewrite the original essay to include an acknowledgement or discussion of criticism and accounting for any of the new developments and ideas within psychology and philosophy for the publication of his book.[24]
