Now here’s the story of how Social Desirability Bias has haunted my life.
The two earliest centers of Social Desirability Bias in my life were Beckford Elementary and Our Lady of Lourdes Catholic church. In school, they told us an endless stream of absurdities – things like, “We’re all going to be great at X!,” “We all take great pride in our school!,” “No one works harder than our teachers,” and so on. I don’t think it bothered me at first. But even in kindergarten, I couldn’t help but notice that not everyone was great at everything. By the time I was in third grade, I knew there were plenty of students who didn’t take pride in the school, and knew of several notoriously lazy teachers.
In catechism, similarly, our Catholic instructors talked a lot about how “We all love each other” even though standard cruel childhood behavior was much in evidence. I noticed the disconnect almost immediately. Once I had my first communion in third grade, I attended weekly Sunday mass, and heard the priests talk at length about “Devoting our lives wholly to God,” “Loving everyone,” “Turning the other cheek,” and “Taking everything you own and giving it to the poor.” Normally, of course, the priests were exhorting us to repent and heed this advice, but they never pointed out that zero parishioners – themselves included – literally complied with any of these exhortations.
As I grew older, I became ever more cynical about school and church. Nobel Junior High School was full of apathetic students, with a noticeable presence of stoners (or at least stoner-wannabees). But the teachers and administrators talked as if we were all eagerly learning together. The P.E. teachers were a notable exception; they openly sneered at the trouble-makers who refused to dress for gym, and freely berated poor athletes like myself – not just for lack of effort, but lack of talent as well. Church, similarly, was agonizingly boring; even now, Morrissey’s “Everyday is Like Sunday” resonates with me. And I obviously wasn’t alone; sitting in the pews, I saw bored children and adults in all directions. But everyone from the priest to my mom spoke as if we were all sharing spiritual ecstasy. And no one acknowledged the cavernous gap between the Sermon on the Mount and the behavior of every person we knew.
By high school, I was loudly and aggressively pointing out the sugar-coated lies of educational and religious authorities. If the principal droned, “I am sure that all Highlanders will try their very best on this week’s standardized exams” over the P.A., I couldn’t wait to sneer, “And I’m sure that the vast majority of Highlanders will barely try at all!” If the priest sanctimoniously announced, “In this coming week we will devote our thoughts entirely to Christ,” I couldn’t wait to scoff to my mom, “More like devote our thoughts entirely to watching t.v.” My friends tended to find my remarks amusing but repetitive. My mom didn’t like them one bit, but she didn’t punish me as long as I sullenly accompanied her to church. By now, I called myself a “cynic.”
At the time, I was an aspiring English professor, or possibly novelist. While fantasy was my go-to genre, I also loved literature that candidly described the world as it really was, instead of sugarcoating. Works like Huckleberry Finn and Shakespeare’s Julius Caesar come to mind. It was only in 11th-grade, however, that I heard of authors who were… gasp… atheists. And the name I kept hearing whispered was… Friedrich Nietzsche. At the library, I discovered a dog-eared yet strangely beautiful edition of Thus Spake Zarathustra; this very translation, if I’m not mistaken.
Zarathustra was a revelation. On so many topics, Nietzsche poetically scoffed at crowd-pleasing nonsense. I loved it – and antagonized friends and family by incessantly quoting it. A century earlier, Nietzsche had declared war on SDB, without knowing the name. When he said, “I love the great despisers, because they are the great adorers, and arrows of longing for the other shore,” I gushed, “He’s talking about me!”
Nietzsche on religion:
“On mine honour, my friend,” answered Zarathustra, “there is nothing of all that whereof thou speakest: there is no devil and no hell. Thy soul will be dead even sooner than thy body: fear, therefore, nothing any more!”
Nietzsche on democracy:
A state? What is that? Well! open now your ears unto me, for now will I say unto you my word concerning the death of peoples.
A state, is called the coldest of all cold monsters. Coldly lieth it also; and this lie creepeth from its mouth: “I, the state, am the people.”
Nietzsche on government generally:
But the state lieth in all languages of good and evil; and whatever it saith it lieth; and whatever it hath it hath stolen.
Nietzsche on his own followers:
Ye venerate me; but what if your veneration should some day collapse? Take heed lest a statue crush you!
Ye say, ye believe in Zarathustra? But of what account is Zarathustra! Ye are my believers: but of what account are all believers!
Ye had not yet sought yourselves: then did ye find me. So do all believers; therefore all belief is of so little account.
In hindsight, I freely admit, Nietzsche was also playing fast and loose with the truth. To call him a “philosopher” is a misnomer; he barely offered arguments and made minimal effort to anticipate or respond to thoughtful criticism. Nietzsche was a great poet, but a poet nonetheless. Still, his odes against SDB spoke to me; a brilliant, famous man saw the same disconnect between popular platitudes and harsh reality that I did.
Later that year, I was excited to hear about another atheist author who had only died a few years earlier. Her name was Ayn Rand, and the first piece of hers I ever read was Francisco d’Anconia’s speech on money. It started off with a critique of Christian ethics:
“So you think that money is the root of all evil?” said Francisco d’Anconia. “Have you ever asked what is the root of money? Money is a tool of exchange, which can’t exist unless there are goods produced and men able to produce them. Money is the material shape of the principle that men who wish to deal with one another must deal by trade and give value for value. Money is not the tool of the moochers, who claim your product by tears, or of the looters, who take it from you by force. Money is made possible only by the men who produce. Is this what you consider evil?
[…]
“Or did you say it’s the love of money that’s the root of all evil? To love a thing is to know and love its nature. To love money is to know and love the fact that money is the creation of the best power within you, and your passkey to trade your effort for the effort of the best among men. It’s the person who would sell his soul for a nickel, who is loudest in proclaiming his hatred of money–and he has good reason to hate it. The lovers of money are willing to work for it. They know they are able to deserve it.”
At root, though, d’Anconia’s speech is a flamboyant attack on Social Desirability Bias itself. The self-appointed champions of the down-trodden are power-hungry would-be tyrants.
“Run for your life from any man who tells you that money is evil. That sentence is the leper’s bell of an approaching looter. So long as men live together on earth and need means to deal with one another–their only substitute, if they abandon money, is the muzzle of a gun.”
My teachers’ heroes were left-wing politicians like FDR. My priests’ heroes were Christian zealots like St. Paul. Rand rolled her eye at both – and said that her heroes were businesspeople.
“To the glory of mankind, there was, for the first and only time in history, a country of money — and I have no higher, more reverent tribute to pay to America, for this means: a country of reason, justice, freedom, production, achievement. For the first time, man’s mind and money were set free, and there were no fortunes-by-conquest, but only fortunes-by-work, and instead of swordsmen and slaves, there appeared the real maker of wealth, the greatest worker, the highest type of human being — the self-made man–the American industrialist.
Within a year, I read almost every word she wrote. Nietzsche was long-forgotten. Rand defied SDB on virtually every issue – and I loved her for it. My lingering worry was that she was economically confused. Could laissez-faire capitalism actually work in practice?
To resolve these doubts, I started studying economics. I began with the Rand-approved Austrians, then moved on to mainstream neoclassical economics and behavioral economics. And within each of these intellectual traditions, I discovered novel defiance of Social Desirability Bias.
Austrians broadly shared Rand’s commitment to laissez-faire capitalism. Mainstream economics, in contrast, helped me see many of Rand’s inadequacies and errors. But carefully interpreted, even left-wing interpretations of mainstream economic theory damn the status quo as a parade of counter-productive and grossly suboptimal policies. Neoclassical economics’ slogan that “Actions speak louder than words” is an intellectual vaccine against SDB. And while social scientists often use behavioral economics to intellectually retrofit standard SDB rationales for government intervention, you can easily use the same framework to criticize government intervention itself. And of course public choice theory, which imputes properly cynical motivations to politicians, is another sharp stake in the heart of SDB. That’s right, you can’t trust politicians to use power for the good of society; instead, you can count on politicians to use power to get more power.
What public choice failed to say loudly and clearly is that voters’ SDB is the key ingredient that makes democracy so inefficient. SDB drives a wedge between public policy and ugly truths about trade-offs and incentives. SDB is what makes people prefer evil controlling politicians to pragmatic live-and-let-live businesspeople. This is basically what I said in my first book, The Myth of the Rational Voter: Why Democracies Choose Bad Policies, though I was still unfamiliar with the psych research and terminology of SDB. With 20/20 hindsight, however, I can say that all of my books revolve around the rejecting of specific expressions of SDB – as well as the whole underlying mentality.
Take my second book, Selfish Reasons to Have More Kids. While twin and adoption research affirms the power heredity over upbringing, that doesn’t sound good. Neither does economic reasoning about the relationship between parental effort and optimal family size. SDB says nonsense like, “Kids can do anything they set their minds to!” and “Just follow your heart.”
The Case Against Education, published in 2018, was my first book to explicitly use SDB to explain the global dominance of education subsidies and the intellectual dominance of the human capital model. Writing it brought me back to elementary school, when I first noticed the chasm between official school rhetoric and actual school experience. Teachers, parents, and politicians all speak as if kids are learning useful skills from dawn to dusk. The actual evidence, in contrast, confirms that education is mostly signaling. As I often say, education is not so much job training as a passport to the real job training, which happens on the job.
My last book, Open Borders, challenges SDB more directly. Most pro-immigration “arguments” focus on emotionally-charged vignettes about particular immigrants. Instead of actually responding to criticism about the broader social effects of immigration, they offer bittersweet biographies of immigrants. I have nothing against such biographies, but what do they really show about optimal immigration policy? Next to nothing. Open Borders, in contrast, focuses almost entirely on arguments.
While writing these books, I’ve also been raising four kids. And I’m proud to say that I’ve successfully raised them without SDB. When my kids ask me questions, however uncomfortable, I either tell them the unvarnished truth or shrug, “I’ll tell you when you’re older.” I love without lies, and as a result my kids trust me and distrust society. As well they should.

I don’t see the common thread. Using the term SDB to cover all ideas that you find to be wrong or platitudinous or hypocritical isn’t making anything clearer. In fact, it’s obfuscating important differences in the ways in which people get things wrong.

The common thread seems clear to me. He’s not using ” the term SDB to cover all ideas that you find to be wrong or platitudinous or hypocritical,” he’s using the term to describe instances of rhetoric or policy which fit the standard definition of SDB – when the truth sounds bad, people prefer to tell a pleasant lie than say the unpleasant truth. And in each section of his story, he specifically highlights how this is the case.
Like with the education system:
Or with childrearing:
I’m not going to beat this drum for every section because then I’ll just be copy-pasting the whole blog post 😛 But at every point, he’s identifying obvious truths which are considered gauche to actually say (“I couldn’t help but notice that not everyone was great at everything. By the time I was in third grade, I knew there were plenty of students who didn’t take pride in the school, and knew of several notoriously lazy teachers”) and pointing out that these realities are ignored in favor of obviously false statements (“We’re all going to be great at X!,” “We all take great pride in our school!,” “No one works harder than our teachers,”) simply because the obviously false statements sound nicer. Policy, in turn, is based on the nice sounding rhetoric rather than reflecting the uglier reality – and when policy is built around an inaccurate reflection of reality, its virtually guaranteed to make things worse.
So on my reading, Caplan isn’t “obfuscating important differences in the ways in which people get things wrong.” He’s clearly arguing that all of these errors stem from the same cause – prioritizing lip service to nice sounding platitudes over clear understanding of unpleasant or mundane realities. Maybe you think he’s wrong that this is what causes people to make these errors (or whether they are errors at all!) but that would be a separate issue.

Yeah, I don’t think he’s right about the motivations. For example, educators have a professional interest in persuading their clients that children can achieve anything. Others may genuinely believe that children can achieve anything. And a third set may say that children can achieve anything in order to be socially desirable. These three motivations seem quite distinct to me.
And the second half of the post is all about Nietzsche and Rand. Is it socially desirable to… not be Ayn Rand? If his claim is, Rand said things that many people disagree with, therefore she’s right, then that’s just silly. But if that’s not his point, then what is? What’s the relation between Rand and the SDB point? None of this is spelled out into an argument I can wrap my head around.

In Atlas Shrugged, the socially desirable thing to say was that love of money was the root of all evil. An attitude many people share. It suggests that a person cares more about their balance sheet than human beings.
The character basically says loving money is great because money allows humans the dignity to trade with each other as equals. That is, commerce is good and even better than charity. Or if this were the 1980s greed is good.
Caplan is saying he agrees with Rand but people disagree because saying I love money sounds gauche.

Thanks. That makes sense. But when someone reaches for fiction as an example of how things are in the real world… I think it’s time to check out. If my drunk mate in the pub argued like this to me, I’d enjoy it! But I’m looking to Econlog for arguments of a higher quality.

I am thinking that your book “Poverty: Who to Blame?” may be the least socially desirable. Your book on Open Borders addressed the issue of intelligence but you spoke about the gains for intelligence with immigration.
If we are going to seriously look at why some nations and people are poor, the topic of IQ is going to arise. I have already heard you discuss this in interviews and I know you mentioned one of the most influential books you read was The Bell Curve.
It will be difficult to navigate this issue. I am concerned that this may cause a lot of backlash even if you are extremely careful. I am worried about your perfect betting record because you recently made one about yourself not being cancelled. I will hope that you speak honestly and don’t fall victim to SDB. Unfortunately, SDB makes talking about serious issues difficult for intellectually honest people.

How do you distinguish SDB from an attempt at motivation?
If the coach of an underdog sports team tells his players “If we give full effort, we are the better team” he is lying, but it is it SDB or motivation? The only chance to win is for them to play at peak level AND the other team slack off. But that isn’t much of a motivational speech, “We can win if they don’t take us seriously!”, even if it is the truth.
But I don’t think that is Social Desirability Bias. The coach isn’t lying to himself, he knows the truth, he just isn’t saying it. Same for the teacher’s in Brian’s examples…maybe. Some of those are clearly SDB, but some could be a motivational attempt.

I think asking “is it SDB or is it motivation” is asking the wrong question. They’re not mutually exclusive. You can just as easily say “they’re giving in to SDB in order to fulfill their desire to motivate.” Motivation is the goal, and playing to SDB is the means to achieve that goal.
The same comes to mind when you say of your hypothetical coach that he “isn’t lying to himself, he knows the truth, he just isn’t saying it.” Social desirability bias isn’t a form of pure delusion – people who play into it can still know the truth and know they aren’t saying it. Like a person who gives into SDB by saying “My church and faith are the most important things in my life!” but whose main religious observances are going to church around Christmas and Easter and sharing occasional memes on Facebook against gay marriage. He’s fully aware that church is actually barely a priority to him, but he also knows that saying that he’s barely interested in church would sound bad to his peer group. So he’s not lying to himself, he knows the truth, and he just doesn’t say it. It would still be social desirability bias.

My concern with most of Bryan’s critical comments against SDB are of a Chesterton Fence variety. I suspect that Bryan believes that SDB was probably evolutionarily adaptive at some point in the past, but is now mostly preventing us from ascending into a relative utopia if only we could move past it and become more like Vulcans. But I wonder: if we had the ability to (voluntarily) use genetic manipulation to remove SDB from the human genome or even just a few humans, would this really make the world a better place? Would it be, all things considered, an improvement or could it make things significantly worse in ways we can’t easily see?

It is useful to observe that Social Desirability Bias influences things like survey responses.
It is not useful to label any and all dissonance you observe in the world as Social Desirability Bias.
There are many different types of rhetoric, not all of which are primarily intended to communicate factual propositions. This is something that an adult should understand.
One of the key insights of neoclassical economics is that the functioning of a system at the aggregate level can often be reliably described and modeled based on an idealized agent’s incentives, even if those incentives are different than the precise ones faced by any real-life agent, and even if an real-life individual agent would not subjectively describe themself as holding the “belief”/value/utility curve of the idealized model agent. That is the “invisible” part of the invisible hand.
I find it very strange to elide this fundamental aspect of aggregated and modeled systems and to instead jump to a conclusion along the lines of “everyone is lying because they are conformist!” Besides needlessly aggrandizing contrarians, if you spend your time focused on everyone supposedly “lying”, you neglect the aspect of systems that is truly deep and tricky: structuring systems that work well despite the individual agent’s subjective motivations. I can tell you what won’t work: yelling at them that they are lying about how they actually feel.

Might we be dealing with an instance of Chesterton’s fence? If we could use genetic manipulation to voluntarily remove any physiological causes for SDB would it really enable us to have a rational utopia? Or would it make things worse in myriad ways? If the latter, when should we give in to SDB, if ever?

Dear Professor Caplan
I think that as an academic, you underestimate the extent to which for most people business is the great home of this sort of social fiction.

I’ll echo the criticism that you may over-attributing errors to SDB. It seems obvious to me that your childhood cynicism regularly misunderstood normative statements to be positive ones because they were stated grammatically as declarations. “We’re going to devote ourselves to Christ” or “we’re going to try hard” are clearly exhortations, not claims about some truth.
Also, I’d be more convinced that all of these views you criticize are due to SDB if people behaved as though they knew they were false after agreeing with them in public. Even rejecting unpleasant truths isn’t necessarily SDB. People often reject truths they’re personally afraid of, rather than to fit in with society. It’s worth making that distinction, especially since these two phenomena tend to lead to different outcomes.
Finally, I can imagine someone with views more or less opposite yours writing the exact same story, in which they reject all the views you see as correct, which they would characterize as ‘socially desirable,’ in favor of the views you oppose, which they would see as uncomfortable truths, and doing so sincerely. E.g., people routinely characterize ‘faith’ in the market and the notion of the economy as meritocratic as a naive myth to justify a horrific reality. So we have mutually exclusive world views whose adherents each believe the opposite worldview is the socially desired one, and they’re the ones giving people the red pill. That itself seems to challenge the notion that the idea that there are a set of views that are widely considered socially desirable. While I don’t doubt SDB is a real thing and there are even some instances where it’s clearly at play, I think you may be too much of a ‘hedgehog,’ in Isiah Berlin’s terms, when it comes to social desirability bias.
