Lying vs. Bullshit

Emeritus professor of philosophy at Princeton Harry Frankfurt‘s book, On Bullshit, was a surprise bestseller a few years ago. Given the public musings about our President, I thought it time to revisit the main idea of the book.

Frankfurt begins by jumping right in: “One of the most salient features of our culture is that there is so much bullshit.” Those of us who with relatively educated and well-ordered minds know the pain we experience when forced to listen to the nonsense spewed by so many politicians, generals, clergy, and uninformed citizens.

But what is bullshitting and in what ways it is similar to, and different from, lying? Here are the basics as Frankfurt sees them:

Main Similarities –

1) Both liars and bullshitters (bsers) want you to believe that they are telling the truth.
2) And both want to get away with something.

Major Differences

Liars – 

1) Liars engage in a conscious act of deception.
2) Liars know the truth, but attempt to hide it.
3) Liars spread untruths, but they still accept the distinction between the truth and false.


1) Bsers don’t consciously deceive.
2) Bsers just don’t know or care about the truth.
3) Bsers ignore or reject the distinction between truth and falsity altogether.

(Note that what the liar says is necessarily false. If I know that Jupiter is a gaseous planet and claim otherwise, then what I’m saying is false. But if I don’t know anything about Jupiter and then make some claim about it, my bullshit might turn out to be correct.)

To reiterate the main point. Liars know the truth and try to hide it; bsers don’t know or care about the truth and try to hide their lack of commitment to it. Thus bullshitting is more like bluffing or faking. Surprisingly, Frankfurt thinks bullshit is more dangerous than lies because it erodes the very idea of truth. As he puts it:

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 bets are off … 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 truth than lies are.

As to the cause of so much bullshit, Frankfurt argues:

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.

Brief reflections – I accept the basic distinction between knowing the truth and lying about it; and not knowing or caring about the truth, and then trying to impress people by talking about things you know nothing about.

I’m less convinced that bullshitting is worse than lying. To clarify, consider the following:

1) I am scientifically literate. Therefore I know that biological evolution is true beyond any reasonable doubt. If I lie about this—say because I think that it will make you more likely to contribute to my political or religious cause—then I subvert the truth.

2) I am scientifically illiterate. Thus I don’t know if evolutionary theory is true or false. If I bullshit about this—say because I want you to think that I know what I’m talking about—then I ignore the truth.

In these two cases, I think lying is worse than bullshitting because the liar always subverts the truth whereas the bser might inadvertently tell the truth.

But if the bser not only doesn’t know or care about the truth but rejects the very distinction between the two, if the bullshitter believes that there is no truth, then bullshitting is worse. A world that denies the existence of truth is far worse than one that still accepts the difference between truth and falsity.

What I think is more important than the distinction between lying and bullshitting is the one between truth and falsity. As Frankfurt states in his follow-up book, On Truth: “How could a society which cared too little for truth make sufficiently well-informed decisions concerning the most suitable disposition of its public business?” I think this is correct, but I think there’s a lot more to it.

In my next post, I will further explore why truth matters.

  1. Doc,
    Sadly my mind is instantly directed toward our current administration. I never thought there would be a day when I would look back and think, “hum, Bush and Nixon weren’t that bad”, but according to the Washington Post, You Know Who has made 22,247 false or misleading claims as of August 27th. Perhaps after the next election we can change the pace from a lying sprint back to the turtle’s pace that we have all been conditioned to tolerate.

    In the spirit of full disclosure, I am not completely averse to lying. Being a fan of comedy and its ability to transcend, and expose, the lunacy of the human condition, I can’t help but think of a skit by Dave Chapelle in which everyone spoke their mind. Spoiler alert, it ends well for no one. Additionally, as soon as I think of BS, my mind also jumps to George Carlin’s “Seven dirty words”—he was a comedic genius and staunch advocate for the dissolution of The Church and fierce proponent for atheism.

    I am of the opinion that there is always room for a few “white” lies but never room for BS. Even George Strait opined that he had some oceanfront property in Arizona and if you’ll buy that he would throw the Golden Gate in for free.

    Doc, this was a great post and the linguist (and nerd) in me was forced to examine the etymology of BS. I suggest you do the same. It was very enlightening and entertaining. I’m looking forward to the post on truth.


  2. The truth may set us free, but bullshitting and lying have sadly been winning a lot of elections. This seems to say more about the audience than the Bullshitters/liars.

  3. I’ve always held a distinction, thus. I lie, a lot, but only to serve an end. To get out of trouble, avoid some expense, to cover up a past mistake or gain an advantage, say in a job application. I’ve always considered bullshit the kinds of pathetic lies dunderheads make, of the sort on how many women they’ve slept with or men they’ve beaten up at once, that everyone present surreptitiously rolls their eyes at.
