The Case Against Education: A Critical Examination
The book "The Case Against Education: Why the Education System Is a Waste of Time and Money," written by economist Bryan Caplan, has sparked considerable debate regarding the purpose and effectiveness of modern education. Caplan's central argument challenges the widely accepted "human capital" model, suggesting that education primarily serves as a signaling mechanism, rather than a means of acquiring valuable skills. This article delves into the core tenets of Caplan's argument, explores its strengths and weaknesses, and considers alternative perspectives on the role of education in society.
The Signaling Model vs. The Human Capital Model
Caplan contrasts a signaling model of education with the commonly held "human capital" model. The human capital model posits that education equips individuals with skills and knowledge that enhance their productivity and contribute to economic growth. Your psychology degree reflects your understanding of the mind and your ability to assess and alter human behavior. In contrast, the signaling model argues that the primary function of education is to signal pre-existing traits, such as intelligence, conscientiousness, and social conformity, that are valued by employers. Signaling considers the utility of the degree to be, instead, a signal of other attributes, especially conscientiousness, intelligence, and social conformity. Notably - and this is a point that’s often egregiously misunderstood - Caplan doesn’t claim that education is all signaling. He argues that it’s at least one-third signaling (in terms of time spent, for example), and probably 80%.
Caplan doesn't claim that education is entirely signaling; he estimates that it accounts for a significant portion, possibly as high as 80%. There’s a big space between one-third and four-fifths, and this isn’t something readily quantifiable anyway, but the key point is that it’s neither 0% nor 100%. He argues that any sizable signaling fraction points to a huge inefficiency, not just in wasted time and money now, but in the continued escalation of waste as the signal becomes more common. A signal is valuable. This perspective suggests that a substantial amount of time and resources invested in education may be misallocated, as the primary benefit lies in signaling rather than skill development.
Evidence for the Signaling Model
Caplan provides a variety of further evidence for the ubiquity of signaling in education, for example the uselessness of almost completing a degree program, despite having almost all the skills associated with the full program. One key piece of evidence supporting the signaling model is the observed correlation between educational attainment and income. Caplan quite clearly lays out how much more money college graduates make compared to high school graduates: 73% more (Chapter 3). College graduate bartenders, for example, earn 60% more than bartenders without a bachelor’s degree, and it’s hard to imagine any other reason than that those hiring them view the degree as an indicator of reliability. While proponents of the human capital model attribute this correlation to the acquisition of skills, Caplan argues that it primarily reflects the signaling value of a degree. The reason for this correlation is what’s at issue. He points to examples such as college graduate bartenders earning significantly more than their non-degreed counterparts, suggesting that employers value the degree as an indicator of reliability and other desirable traits. At the level of individuals, a college degree can be lucrative. At the level of society, as we encourage almost everyone to take this track, is it beneficial?
Moreover, Caplan highlights the phenomenon of students seeking out easier classes and majors, rather than those with the most learning potential. Are there cheaper, more humanistic, and more enriching ways to accomplish our goals (whatever they may be)? He questions why forgetting course content doesn't have the same consequences as failing the course, further challenging the notion that education is primarily about acquiring knowledge. A few weeks into every semester, I face a lecture hall that is half-empty, despite the fact that I am repeatedly voted a Harvard Yearbook Favorite Professor, that the lectures are not video-recorded, and that they are the only source of certain material that will be on the exam.

Counterarguments and Limitations
Caplan's thesis has faced criticism from various quarters. One common objection is that certain fields, such as physics, biology, or computer science, involve the acquisition of substantial knowledge and skills that go beyond mere signaling. A common response to the idea that education is mostly signaling is that being a physics, or biology, or computer science major isn’t mostly signaling - there’s actual physics, biology, or computer science that one learns. This is true. However, most students aren’t physics, biology, or computer science majors. The most common major here at the University of Oregon (and a common one everywhere) is business, a hodgepodge of stuff whose rigor I’ve never heard anyone defend. A side-effect of teaching a lot of courses for non-science majors is that I chat with students about the range of things they’re actually majoring in - business, sociology, public relations, … It’s this that one should consider if thinking about the median signaling component of an undergraduate degree. While acknowledging the importance of these fields, Caplan argues that they represent a minority of students, with the majority pursuing less rigorous majors where signaling plays a more prominent role.
Another common objection is that the aim of education is to enrich the soul, not to provide specific, practical skills. I am very sympathetic to this objection, being fond of art, science, and learning in general for their own sake. Caplan claims that he is too, and devotes a whole chapter to this topic (Chapter 9) that includes a long quote from Malcolm X on the wonder of reading. The main counter-objection is that culture is more accessible than it has ever been, and doesn’t need the intermediary of university classes, even if they were effective in imparting refined tastes. Chapter 9 is a mix of good and poor arguments, but I’ll leave it at that. I’ll add, though, that I’d be happier with the cultural objection if universities weren’t so keen on watering down any requirements that might make one numerate or well read. The cultural argument suggests that education's purpose extends beyond economic considerations to encompass personal growth and intellectual development. Caplan counters that culture is more accessible than it has ever been, and doesn’t need the intermediary of university classes, even if they were effective in imparting refined tastes.
The biggest flaw is that its claims span K-12 education and higher education. Applying these arguments to high school, however, is unconvincing. Not only are basic skills in writing, math, etc., that open doors to many paths developed there, but the relative uniformity of the curriculum provides a shared background for everyone. Caplan complains about the constrictions of school with “I love education too much to accept our Orwellian substitute” [p. 260], missing the irony that most of us know what Orwellian means thanks to mass high school education. Furthermore, Caplan's analysis primarily focuses on economic outcomes, potentially neglecting the broader societal benefits of education, such as fostering informed citizenship and promoting social cohesion. Another flaw is that the presumed aims of education are phrased almost completely in economic terms, as preparing people for employment. As noted above, Caplan argues that culture and general enrichment are important, but argues against the education system being necessary or important for promoting that.
Third, even if one accepts the signaling model, the question arises as to whether education improves the traits that are being signaled. Caplan writes, “The labor market… pays you for the preexisting traits you reveal…” [p. 13] Are these really pre-existing, or are they developed by study? Caplan does address this (Chapter 3), but rather minimally, noting that there is little research on whether education itself improves things like conscientiousness. Finally, I’ll note that the book is very repetitive. Caplan’s overall recommendation is that we should spend less on education. Not only is it wasteful in itself, but if much of education is signaling, the “subsidies [we provide] raise the correlation between educational attainment and employability” [p 214]. Another limitation is that the presumed aims of education are phrased almost completely in economic terms, as preparing people for employment. As noted above, Caplan argues that culture and general enrichment are important, but argues against the education system being necessary or important for promoting that.

Implications and Recommendations
Caplan’s overall recommendation is that we should spend less on education. Not only is it wasteful in itself, but if much of education is signaling, the “subsidies [we provide] raise the correlation between educational attainment and employability” [p 214]. The current system is “a dysfunctional game, but if you refuse to play, the labor market brands you a loser.” This escalates, as the signal grows more common and its value as a signal declines. Already, we’re seeing the proliferation of Master’s degrees, because a Bachelor’s in itself isn’t distinctive. The cost of education, spiraling ever upwards, falls especially hard on the poor. Further subsidizing education - or worse, forgiving loans, our recently enacted policy that will serve as a giant green light to every university to increase its tuition - further dilutes the signal, and the benefit to the student.
Caplan's analysis leads him to advocate for reduced government spending on education. He argues that subsidizing education dilutes the signaling value of degrees and exacerbates the financial burden on students, particularly the poor. Aside from lowering our spending, Caplan doesn’t have many concrete suggestions. He envisions a world in which there is more free play, library time, etc., for young people. He also proposes education as a tour of activities and occupations to connect students with the “real world,” but this is rather vague. Caplan wants to be provocative, and he needlessly overstates his case. He envisions a world with more free play and exploration for young people, along with vocational training to connect students with the "real world."
However, Caplan's recommendations have been criticized for neglecting the potential benefits of education beyond signaling, such as fostering critical thinking, promoting civic engagement, and enhancing personal development.
Alternative Perspectives and Solutions
While signaling is dominant in a world where students are competing to be hired by employers, in a world with more entrepreneurship I suspect students would demand more authentic human capital development. The market corrects skill vs. credential disparities faster when people are selling products than when they are in a bureaucracy. I would be very interested in seeing a fuller analysis of this, but my sense is that the rise of high school and then college enrollment in the US roughly tracks the shift in the US labor market away from farmers and little-c capitalists towards larger corporations. I see this dynamic play out in Silicon Valley: Credentials are still valued, but uncredentialed talented folks can pretty quickly establish themselves by making things people want.
Different perspectives offer alternative solutions to address the perceived inefficiencies of the education system. One approach emphasizes the importance of aligning education with the demands of a changing labor market, promoting entrepreneurship, and fostering authentic human capital development. While signaling is dominant in a world where students are competing to be hired by employers, in a world with more entrepreneurship I suspect students would demand more authentic human capital development.

Another perspective focuses on reforming the curriculum to make it more relevant and engaging for students. The market corrects skill vs. credential disparities faster when people are selling products than when they are in a bureaucracy. I would be very interested in seeing a fuller analysis of this, but my sense is that the rise of high school and then college enrollment in the US roughly tracks the shift in the US labor market away from farmers and little-c capitalists towards larger corporations. What schools teach is determined by state standards and tests, which is in turn decided by a very small number of career academics; the system is designed to be great preparation for academics and lousy for everyone else. I loved the book’s points about the internet making “enlightenment” more available than ever, but that it is still wildly underutilized because most students are apathetic about what adults ask them to learn. Individual schools can and do chip away at the margin, but what constitutes the core curriculum is enshrined in stone - specifically, policies like the UC A-G admission requirements and the accreditation process schools must go through for their students’ transcripts to grant admission to college.
Some people think the answer is that employers fear getting sued: in the 1971 Griggs vs. Duke Power case, the Supreme Court ruled that employment tests are illegal if they disproportionately screen out minorities.
