I agree, I started reading Harari, but after a few dozen pages, I realized that his discourse was biased, with false negatives like faith and family, and that it was above all a very elaborate intellectual construct intended to convince pessimistic and impressionable people.https://davidepiffer.com/p/what-hararis-sapiens-gets-wrong
What Harari’s Sapiens Gets Wrong
Why Harari’s most memorable ideas mislead
When I first read Sapiens by Yuval Noah Harari (Yuval Noah Harari, Sapiens: A Brief History of Humankind (2011), I could not put it down. I finished it in two days. The book is fast, confident, and full of striking claims that seem to tie together human evolution, culture, and history into a single coherent story.
That readability is its greatest strength. Unfortunately, it is also the source of its biggest problems.
Sapiens does not mainly get facts wrong. It goes wrong by replacing slow, uncertain explanations with clean, decisive stories. Below are four central claims from the book, supported by Harari’s own words, that show how this happens.
To be fair, this is partly a timing issue. The first edition appeared in 2011, before ancient DNA transformed prehistory and before modern polygenic methods made it possible to study long-run genetic change at scale. In other words, Harari wrote before many of today’s best tools existed. That makes the book easier to excuse, but also more important to revisit, because its influence has only grown while the empirical landscape has changed. Moreover, many scientific articles still rely on the same misconceptions, as I have discussed in
1) The “Cognitive Revolution” as a sudden event
Harari presents the Cognitive Revolution as a sharp break, a one-time switch after which biology fades into the background:
“The Cognitive Revolution is accordingly the point when history declared its independence from biology.”
He also describes it as a bounded window in time, with uncertain causes:
“The appearance of new ways of thinking and communicating, between 70,000 and 30,000 years ago, constitutes the Cognitive Revolution.”
That packaging encourages a very specific mental model: first, a biological upgrade; then, mostly culture.
Ancient DNA points in the opposite direction, towards an acceleration of cognitive evolution after the Upper Paleolithic. Over the Holocene, polygenic scores associated with cognition and educational attainment show sustained directional change in multiple time-series analyses, on the order of roughly a standard deviation depending on the trait, method, and sample definitions. This pattern fits a long runway of cognitive evolution, possibly kickstarting a positive feedback loop with the invention of farming, not a single “revolution” after which selection stops.
Something consequential clearly happened in the Late Pleistocene: symbolic behavior spreads, toolkits become more flexible, and humans begin to reshape ecosystems in ways that earlier hominins never managed. The problem is the way Harari packages this shift as a single “Cognitive Revolution,” because that label quietly implies a discrete upgrade followed by a long cultural afterparty, as if biology steps off the stage once the curtain rises on storytelling and cooperation. A better framing is cognitive evolution, meaning a sequence of changes, uneven across time and place, that continues and even accelerates into the Holocene rather than concluding before agriculture.
2) The Agricultural Revolution as “fraud,” and the problem of measuring happiness
Harari’s most viral line is not subtle:
“The Agricultural Revolution was history’s biggest fraud.”
He then sharpens the claim by flipping agency:
“These plants domesticated Homo sapiens, rather than vice versa.”
This is memorable, and it is also a framing trap.
Yes, early farming is often associated with heavier labor, higher pathogen load, and worse dental and skeletal indicators in some contexts. But “fraud” is a moral verdict that implies a unified deception and a unified victim. The transition to agriculture was neither. It unfolded unevenly across regions, often mixed with foraging for long periods, and was tightly linked to storage, property, inheritance, warfare, and expanding population. You can tell a tragic version of that story, but calling it a fraud preloads the conclusion.
What often goes unnoticed is how old this narrative structure is. The contrast between a lost foraging idyll and a fallen agricultural world long predates Harari. Versions of it appear at least as early as Jean-Jacques Rousseau, whose critique of inequality rested on an idealized vision of pre-agricultural humans as freer, healthier, and less corrupted by social institutions. The same intuition reappears centuries later in anthropology, most famously in the idea of the “original affluent society,” popularized by Marshall Sahlins in Stone Age Economics. Hunter-gatherers were portrayed as working only a few hours a day, enjoying abundant leisure, and meeting their needs with minimal stress.
Harari’s account echoes this tradition, even when it is presented as a counterintuitive modern insight. The rhetoric is familiar: foragers were healthier and happier, farmers were trapped into harder lives, and history took a wrong turn. What changes is not the structure of the argument, but the confidence with which it is delivered to a mass audience.
More importantly, the claim rests on an evaluation metric that sounds firm and turns out to be slippery. Harari wants to drive a wedge between evolutionary success and lived experience, and he gives it his own grand framing:
“This discrepancy between evolutionary success and individual suffering is perhaps the most important lesson we can draw from the Agricultural Revolution.”
There is a real idea here. Reproductive success and subjective experience are not the same thing. A population can grow while daily life becomes harsher. The difficulty lies in how confidently the book treats “suffering” and “happiness” as if they were easy to measure across millennia.
Harari does not perform a systematic quantitative review. Instead, he selects illustrative signals, typically stature, skeletal stress markers, and fragmentary reconstructions of lifespan, then assembles them into a sweeping verdict. Even if every cited datapoint were correct, and setting aside the fact that differences in stature between foragers and farmers are partly mediated by genetics rather than nutrition alone(as I have shown here using ancient DNA:
the inferential leap is still doing the heavy lifting. Shorter stature becomes “worse life,” worse life becomes “suffering,” and suffering becomes “fraud,” applied to a transition that played out very differently across ecologies and centuries.
There is also a deeper conceptual move embedded in the rhetoric. The book implicitly treats happiness as comfort plus pleasure minus stress, filtered through modern intuitions about what a good life should look like. That is an oddly confident stance, given how much human motivation revolves around meaning, duty, status, family continuity, and identity rather than uninterrupted comfort.
A simple example makes the point. Imagine parents who choose to have many children. They accept years of sleep deprivation, financial pressure, and reduced leisure. A childless couple with long holidays, quiet mornings, and abundant free time may report higher day-to-day enjoyment. If happiness is scored as hedonic smoothness, the parents look irrational and the childless couple looks like the clear winner.
Yet most humans do not experience the choice that way. Many parents experience the hardship as inseparable from purpose, attachment, and continuity. Even the instincts Harari likes to demystify are pointing toward something real here.
People repeatedly choose lives that are harder but more meaningful.
A framework that assumes these choices reflect confusion or false consciousness, and that an external observer can adjudicate “true happiness” on their behalf, risks becoming superficial while sounding unsentimental.
This is why Harari’s contrast between evolutionary success and suffering resonates and still misleads. The insight does not require a theatrical verdict on agriculture, and it does not require treating subjective wellbeing as a clean, comparable variable across deep time.
The same temptation appears in modern commentary. People speculate that poorer countries are happier than they would be after industrialization because life is simpler and communities are tighter. Others argue that smartphones and social media turned us into unhappy slaves. Sometimes there is truth in these claims. The problem is the speed with which they harden into total judgments, supported by selective proxies and a narrow definition of happiness.
Harari’s agriculture chapter works extremely well as provocation. As analysis, it leans too heavily on slogans and on a measure of suffering that is far harder to quantify than the rhetoric suggests.
3) Imagined orders, hierarchy, and a familiar idea presented as revelation
A central theme of Sapiens is that large-scale human cooperation depends on shared symbols. Harari groups language, money, law, nations, corporations, and social hierarchies under the label of “imagined orders.” They are not biological facts, yet they shape behavior because people collectively act as if they were real.
He states this explicitly:
“Every person is born into a pre-existing imagined order, and his or her desires are shaped from birth by its dominant myths.”
As a description of how social coordination works, this is largely correct. Language itself fits perfectly into this category. Words are arbitrary symbols, grammar is conventional, and meaning exists only because speakers converge on shared rules. No one concludes from this that language is fake or dispensable. Its conventional nature is precisely what allows it to scale.
What Sapiens presents as a striking insight, however, is not new. The idea that institutions exist through collective recognition has a long pedigree in social theory and philosophy. Sociologists have long treated norms and institutions as external constraints that are socially produced. Political theorists have described nations as imagined communities. Philosophers have analyzed money, law, and rights as institutional facts created through shared acceptance and linguistic conventions. Harari’s contribution is synthesis and exposition, not conceptual invention.
This matters because the book’s presentation can give the impression that labeling institutions “imagined” is itself an explanation, when it is really a starting point.
4) Human rights reduced to “imagined reality,” without the missing distinction
Harari loves demystifying sacred cows, and sometimes he does it with a sledgehammer:
“Homo sapiens has no natural rights…”
He extends the point in a deliberately provocative passage:
“If people realise that human rights exist only in the imagination, isn’t there a danger that our society will collapse?”
There is a defensible descriptive claim here: rights are not physical properties like mass or temperature. They are social facts, stabilized by collective belief and enforcement. The problem is that Harari blurs two different questions:
What kind of thing is a right, descriptively?
What should we commit to, normatively?
By collapsing them into one, the book invites a cheap cynicism: since rights are “imagined,” they are optional, fake, or merely propaganda. Yet plenty of real things are socially constructed and still binding, including language, contracts, property, scientific institutions, and money, which Harari treats with more respect.
If you want to say “rights are invented,” fine. The missing follow-up is that invented does not mean arbitrary, and constructed does not mean disposable. A system can be intersubjective and still be the best technology we have for restraining power.
Closing thought
Sapiens is at its best when it slows down, weighs multiple causes, and acknowledges uncertainty. It is at its weakest when complex historical processes are compressed into slogans designed to be quoted. The book teaches readers to distrust myths, then builds its own myth-shaped narrative to carry them through 70,000 years.
A version of the book that holds up better today would not abandon the ambition of telling a unified story of Homo sapiens. It would tighten the contract with the reader. It would treat sweeping claims as provisional where the data are sparse, and it would replace global slogans with explicit bounds on what can be inferred. It would also update its central labels. The “Cognitive Revolution” framing suggests a one-time jump followed by a mostly cultural story. Ancient DNA evidence and polygenic time series point instead to continued cognitive change during the Holocene, on a scale large enough to make “revolution” a misleading title. The cleaner narrative is cognitive evolution, and the interesting part is that it did not stop
