The question addressed in this chapter is whether the concepts of post-truth and bullshit are useful tools of politico-epistemological analysis in relation to political events in the U.S. and U.K. since 2016. Bullshitters are understood as knowingly ignorant individuals who conceal their ignorance by pretending to know what they do not know or understand what they do not understand. This account is compared to other accounts of bullshit, including Frankfurt’s. Three notions of post-truth are distinguished. The concepts of post-truth and bullshit are shown not to provide for an adequate conceptualization of the political tactics that have come to the fore in recent years. An emphasis on bullshit and post-truth trivializes and misdescribes these tactics, which are more adequately conceptualized in terms of notions such as propaganda and hate speech.
