The ever-widening ideological chasms in modern society often evoke fears of a «post-truth» age, where objective facts are rendered irrelevant, and narratives reign supreme. However, in The Bias That Divides Us: The Science and Politics of Myside Thinking, cognitive scientist Keith E. Stanovich offers a deeper and more unsettling diagnosis. The true problem, he argues, is not that people no longer value truth, but that our natural cognitive wiring makes us view evidence and arguments in ways that reinforce our existing beliefs—a phenomenon he terms myside bias.
Myside bias, as Stanovich explores in painstaking detail, is not merely a quirk of human reasoning but a universal feature of cognition. It is pervasive across all levels of society and is strikingly resistant to conventional correctives like education, intelligence, or expertise. Instead, it quietly but inexorably fuels the polarization, distrust, and dysfunction that characterize contemporary public life. His book is not just an exploration of this phenomenon but a clarion call to address it before it further undermines the foundations of democracy and cooperation.

What Is Myside Bias?
Myside bias is a cognitive tendency to evaluate information, arguments, and evidence in a way that favors one’s pre-existing beliefs, ideologies, or group loyalties. Unlike biases that are linked to ignorance or lack of critical thinking, myside bias operates even—perhaps especially—among those who pride themselves on being rational, educated, or intellectually rigorous.
Stanovich makes the startling observation that myside bias is impervious to intelligence. In fact, intelligent individuals are often better at rationalizing their beliefs, constructing sophisticated arguments to support their views while dismissing contradictory evidence. This phenomenon, known as «motivated reasoning,» highlights a paradox: the very tools that should promote objectivity and fairness are often wielded in service of bias.
The implications are profound. If intelligence and education do not protect against myside bias, then societies cannot rely solely on these attributes to foster reasoned debate and informed decision-making. Instead, the cognitive blind spots created by myside bias require direct and deliberate intervention.
A Universal Human Vulnerability
A key strength of Stanovich’s analysis is his insistence that myside bias is not confined to any one ideological group. It is a universal human tendency, affecting people on both ends of the political spectrum and across all social strata. This universality makes myside bias uniquely insidious, as it allows individuals to perceive their own reasoning as objective while labeling others as biased or irrational.
Stanovich dismantles the comforting myth that myside bias is a problem for «the other side»—whether that «other side» is defined politically, culturally, or intellectually. For example, he notes that climate change skeptics and climate activists alike exhibit myside bias, interpreting data through the lens of their prior beliefs. Similarly, debates over issues like vaccine mandates, immigration policy, and economic inequality are shaped less by evidence than by the competing narratives individuals bring to the table.
This insight has significant implications for understanding polarization. It suggests that societal divisions are not merely the result of bad actors or malicious intent but are rooted in the cognitive architecture of the human mind. Addressing polarization, therefore, requires addressing the psychological mechanisms that drive it.
The Myside Society
Stanovich introduces the concept of a «myside society» to describe the current state of public discourse. In this society, people still value truth and facts but interpret them in ways that align with their group identities. Each faction sees itself as the guardian of truth, dismissing the other side as either ignorant or deceitful.
This dynamic has corrosive effects on societal trust. Neutral institutions such as science, journalism, and academia, which are supposed to serve as arbiters of truth, become battlegrounds for ideological warfare. When these institutions are perceived as biased, their authority erodes, leaving society without a common framework for resolving disputes or evaluating evidence.
Stanovich argues that the rise of the myside society is not a new phenomenon but has been exacerbated by modern technologies and media environments. Social media, in particular, amplifies myside bias by curating content that aligns with users’ existing views, creating echo chambers where alternative perspectives are rarely encountered or taken seriously.
Implications for Politics and Governance
The political ramifications of myside bias are immense. In democratic systems, compromise and negotiation are essential for effective governance. However, myside bias makes compromise increasingly difficult by framing it as a betrayal of core values. Each side views concessions as capitulation, leading to gridlock and an inability to address pressing societal challenges.
This dynamic is particularly evident in «culture war» issues, where debates are less about evidence and more about identity. Topics such as climate change, healthcare policy, and education reform become symbolic battlegrounds, with each side using evidence selectively to bolster its narrative. The result is a kind of performative debate, where the goal is not to persuade or find common ground but to score ideological points.
Stanovich also highlights how myside bias erodes the quality of public discourse. When individuals are convinced of their own objectivity and the other side’s irrationality, meaningful dialogue becomes nearly impossible. Instead, discussions devolve into shouting matches, further entrenching divisions and alienating those who might otherwise seek consensus.
Addressing the Bias That Divides Us
Despite the challenges posed by myside bias, Stanovich is not without hope. He argues that recognizing the universality of this bias is the first step toward addressing it. By acknowledging that everyone is susceptible, individuals can begin to question their assumptions and approach evidence with greater humility.
To counteract myside bias, Stanovich advocates for systemic changes in education and public discourse. Schools should prioritize teaching critical thinking and cognitive flexibility, helping students develop the skills to evaluate evidence objectively and consider alternative perspectives. Such education must go beyond rote learning to focus on the psychological barriers to open-mindedness.
At the societal level, Stanovich calls for fostering environments that encourage constructive dialogue. This includes creating forums where diverse perspectives can be aired without fear of ridicule or hostility. Leaders, too, have a role to play by modeling humility and a willingness to listen, even at the risk of alienating their base.
A Blueprint for Bridging Divides
The Bias That Divides Us is a deeply insightful and timely book, offering both a diagnosis of societal polarization and a roadmap for addressing it. Stanovich’s emphasis on the cognitive roots of division provides a fresh perspective, moving beyond simplistic explanations that blame one political faction or another. Instead, he challenges readers to confront the biases within themselves and their communities.
For policymakers, educators, and anyone concerned about the future of democracy, Stanovich’s work is an urgent reminder that the biases dividing us are not insurmountable. However, overcoming them requires effort, humility, and a commitment to fostering environments where truth and reason can flourish.
Ultimately, Stanovich’s message is as challenging as it is hopeful: the path to unity begins with the recognition that the bias dividing us resides in each of us. By addressing this shared vulnerability, we can begin to rebuild trust, restore dialogue, and create a society capable of navigating its differences with wisdom and grace.
