Why Common Sense Is a Social Construct—Not an Instinct
People like to throw around the phrase “common sense” as if it were some universal instinct hardwired into the human brain. The problem? What we call “common sense” isn’t common, isn’t natural, and sure as hell isn’t universal. It’s a cultural agreement, a social construct, and often a lazy shortcut we use to dismiss complexity. In reality, what counts as “common sense” is shaped by upbringing, socialization, history, and power structures. Let’s break it down with the help of a few big thinkers.
Thomas Reid: The Philosopher of “Common Sense”
Scottish philosopher Thomas Reid (1710–1796) argued that “common sense” formed the bedrock of human knowledge. For him, it was self-evident truths we didn’t need to prove—like trusting our senses or believing the external world exists. Reid believed these truths were natural and God-given. But here’s the catch: Reid’s “common sense” referred more to epistemic trust in perception than to cultural norms. What we’ve inherited in everyday language is not Reid’s carefully framed philosophy but a watered-down, oversimplified notion that what “everybody knows” is automatically valid. In short: Reid’s theory has been hijacked to justify social conformity rather than philosophical inquiry.
Dr. Benjamin Spock: Parenting and the Learned Nature of “Sense”
Fast-forward to the 20th century. Dr. Benjamin Spock—pediatrician and cultural icon—taught parents to trust themselves and nurture individuality in children. His view shows that what’s considered “common sense” in raising kids is anything but instinctive. For centuries, child-rearing was harsh, authoritarian, and rooted in “spare the rod” thinking. Spock’s advice, which emphasized warmth and responsiveness, was revolutionary—yet is now widely seen as common sense parenting. That shift alone proves the point: common sense is not instinct, but rather what a society decides to normalize.
Peter Berger & Thomas Luckmann: Reality Is Constructed
Sociologists Peter Berger and Thomas Luckmann, famously declared that reality itself is socially constructed. In The Social Construction of Reality (1966), they argued that what we take for granted—institutions, knowledge, morality—are human creations maintained by social agreement. From this angle, “common sense” is nothing more than institutionalized knowledge that we stop questioning. It feels “natural” because society repeats it so often that it becomes part of the furniture of everyday life. But strip away the social scaffolding, and that “common sense” evaporates.
Alfred Schutz: The Everyday World of Assumptions
Phenomenologist Alfred Schutz picked up where Berger left off, showing how our daily interactions rely on a background of shared assumptions. He called it the “lifeworld;” a stock of knowledge that allows us to navigate reality without constantly questioning it. For Schutz, “common sense” isn’t instinct but an accumulation of cultural routines that make social life efficient. We don’t stop at every corner to renegotiate whether red means “stop” and green means “go.” We just accept it—until we travel to a place where the rules shift and suddenly realize our “common sense” was never universal.
Émile Durkheim: Social Facts Rule Us
Durkheim, the heavyweight of sociology, would argue that common sense is a social fact: external, coercive, and imposed on individuals by society. It exists outside of us but shapes us, whether we agree with it or not. For example, the idea that “hard work pays off” functions as common sense in American society. But it’s not instinct—it’s a moral directive embedded in the collective consciousness. If you challenge it, you risk social sanctions. Durkheim shows us that “common sense” is not born in our biology but imposed by the social order.
Why This Matters
If we keep treating common sense as instinct, we risk ignoring how deeply culture and history shape human judgment. What feels “obvious” to you may feel absurd to someone raised under different conditions. By recognizing common sense as socially constructed, we open the door to better cross-cultural communication, critical thinking, and humility. Instead of asking, “Why don’t they use common sense?”—a question soaked in judgment—we might ask, “What assumptions are shaping my version of common sense?” That’s a far more productive (and human) approach.
In The End It’s Just Made-Up
Common sense isn’t born into us. It’s taught, reinforced, policed, and passed off as natural. If you really want to exercise wisdom, stop leaning on “common sense” as a crutch. Instead, recognize it for what it is: a cultural script, not a biological instinct. From Reid’s philosophy to Durkheim’s collective consciousness, the verdict is clear: common sense is a social construct, not an instinct.
