[Update: After I posted this I came across a great study – “On the reception and detection of pseudo-profound bullshit” [PDF] – freshly published in November 2015. Well worth a read. I also recently came across this old but great post from Scott Berkun “How to Detect Bullshit“]
Because I see so much of this on Facebook, I wanted to post the classic essay “On Bullshit” by Harry G. Frankfurt.
Here is Wikipedia on the essay:
“On Bullshit (2005), by Harry G. Frankfurt, is a philosophical essay that presents a theory of bullshit that defines the concept and analyzes the applications of bullshit in the contexts of communication. As such, bullshit can be neither true nor false; hence, the bullshitter is someone whose principal aim — when uttering or publishing bullshit — is to impress the listener and the reader with words that communicate an impression that something is being or has been done, words that are neither true nor false, and so obscure the facts of the matter being discussed. In contrast, the liar must know the truth of the matter under discussion, in order to better conceal it from the listener or the reader being deceived with a lie; while the bullshitter’s sole concern is personal advancement and advantage to their own agenda.”
Here are some quotes:
Humbug is not designed primarily to give its audience a false belief about whatever state of affairs may be the topic, but that its primary intention is rather to give its audience a false impression concerning what is going on in the mind of the speaker. Insofar as it is humbug, the creation of this impression is its main purpose and its point.
Consider a Fourth of July orator, who goes on bombastically about “our great and blessed country, whose Founding-Fathers under divine guidance created a new beginning for mankind.” This is surely humbug. …the orator is not lying. He would be lying only if it were his intention to bring about in his audience beliefs which he himself regards as false, concerning such matters as whether our country is great, whether it is blessed, whether the Founders had divine guidance, and whether what they did was in fact to create a new beginning for mankind. But the orator does not really care what his audience thinks about the Founding Fathers, or about the role of the deity in our country’s history, or the like. At least, it is not an interest in what anyone thinks about these matters that motivates his speech. It is clear that what makes Fourth of July oration humbug is not fundamentally that the speaker regards his statements as false. Rather…the orator intends these statements to convey a certain impression of himself. He is not trying to deceive anyone concerning American history. What he cares about is what people think of him.
…Her statement is grounded neither in a belief that it is true nor, as a lie must be, in a belief that it is not true. It is just this lack of connection to a concern with truth – this indifference to how things really are – that I regard as of the essence of bullshit.
…The characteristic topics of a bull session have to do with very personal and emotion-laden aspects of life for instance, religion, politics, or sex. People are generally reluctant to speak altogether openly about these topics if they expect that they might be taken too seriously. What tends to go on in a bull session is that the participants try out various thoughts and attitudes in order to see how it feels to hear themselves saying such things and in order to discover how others respond, without it being assumed that they are committed to what they say: It is understood by everyone in a bull session that the statements people make do not necessarily reveal what they really believe or how they really feel. The main point is to make possible a high level of candor and an experimental or adventuresome approach to the subjects under discussion. Therefore provision is made for enjoying a certain irresponsibility, so that people will be encouraged to convey what is on their minds without too much anxiety that they will be held to it.
…Each of the contributors to a bull session relies, in other words, upon a general recognition that what he expresses or says is not to be understood as being what he means wholeheartedly or believes unequivocally to be true. The purpose of the conversation is not to communicate beliefs. Accordingly, the usual assumptions about the connection between what people say and what they believe are suspended. The statements made in a bull session differ from bullshit in that there is no pretence that this connection is being sustained. They are like bullshit by virtue of the fact that they are in some degree unconstrained by a concern with truth.
…It is impossible for someone to lie unless he thinks he knows the truth. Producing bullshit requires no such conviction. A person who lies is thereby responding to the truth, and he is to that extent respectful of it. When an honest man speaks, he says only what he believes to be true; and for the liar, it is correspondingly indispensable that he considers his statements to be false. For the bullshitter, however, all these bets are off: he is neither on the side of the true nor on the side of the false. His eye is not on the facts at all, as the eyes of the honest man and of the liar are, except insofar as they may be pertinent to his interest in getting away with what he says. He does not care whether the things he says describe reality correctly. He just picks them out, or makes them up, to suit his purpose.
…Someone who lies and someone who tells the truth are playing on opposite sides, so to speak, in the same game. Each responds to the facts as he understands them, although the response of the one is guided by the authority of the truth, while the response of the other defies that authority and refuses to meet its demands. The bullshitter ignores these demands altogether. He does not reject the authority of the truth, as the liar does, and oppose himself to it. He pays no attention to it at all. By virtue of this, bullshit is a greater enemy of the truth than lies are.
One who is concerned to report or to conceal the facts assumes that there are indeed facts that are in some way both determinate and knowable. His interest in telling the truth or in lying presupposes that there is a difference between getting things wrong and getting them right, and that it is at least occasionally possible to tell the difference. Someone who ceases to believe in the possibility of identifying certain statements as true and others as false can have only two alternatives. The first is to desist both from efforts to tell the truth and from efforts to deceive. This would mean refraining from making any assertion whatever about the facts. The second alternative is to continue making assertions that purport to describe the way things are but that cannot be anything except bullshit.
Bullshit is unavoidable whenever circumstances require someone to talk without knowing what he is talking about. Thus the production of bullshit is stimulated whenever a person’s obligations or opportunities to speak about some topic are more excessive than his knowledge of the facts that are relevant to that topic. This discrepancy is common in public life, where people are frequently impelled – whether by their own propensities or by the demands of others – to speak extensively about matters of which they are to some degree ignorant. Closely related instances arise from the widespread conviction that it is the responsibility of a citizen in a democracy to have opinions about everything, or at least everything that pertains to the conduct of his country’s affairs. The lack of any significant connection between a person’s opinions and his apprehension of reality will be even more severe, needless to say, for someone who believes it his responsibility, as a conscientious moral agent, to evaluate events and conditions in all parts of the world.
The contemporary proliferation of bullshit also has deeper sources, in various forms of scepticism which deny that we can have any reliable access to an objective reality and which therefore reject the possibility of knowing how things truly are. These “anti-realist” doctrines undermine confidence in the value of disinterested efforts to determine what is true and what is false, and even in the intelligibility of the notion of objective inquiry. One response to this loss of confidence has been a retreat from the discipline required by dedication to the ideal of correctness to a quite different sort of discipline, which is imposed by pursuit of an alternative ideal, sincerity. Rather than seeking primarily to arrive at accurate representations of a common world, the individual turns toward trying to provide honest representations of himself. Convinced that reality has no inherent nature, which he might hope to identify as the truth about things, he devotes himself to being true to his own nature. It is as though he decides that since it makes no sense to try to be true to the facts, he must therefore try instead to be true to himself.
…Facts about ourselves are not peculiarly solid and resistant to skeptical dissolution. Our natures are, indeed, elusively insubstantial – notoriously less stable and less inherent than the natures of other things. And insofar as this is the case, sincerity itself is bullshit.
