Why We Struggle with Difference – the Rise of Black and White Thinking

Many people feel that the current social climate has become increasingly toxic and polarised. Disagreements around politics, gender rights, land ownership and cancel culture often escalate quickly into hostility. Positions appear more extreme, and the ability to tolerate difference seems to be shrinking.

History has certainly seen similar periods of division, so it would be simplistic to claim that our moment is uniquely fractured. Yet something does appear to be happening in the way we manage disagreement. Conversations that once might have allowed room for nuance often collapse into rigid “us versus them” positions rather than curiosity about different perspectives. Psychotherapy offers several insights into why difference can feel so difficult.

Early Experiences of Separation

One explanation lies in early development. Attachment theorist John Bowlby proposed that babies initially experience themselves as inseparable from their primary caregiver. In the first weeks after birth they begin to recognise that the caregiver is a separate person. This moment marks the beginning of a lifelong process of learning to tolerate difference and separation.
Human development unfolds through a series of transitions: moving from breast or bottle to solid food, starting school, leaving home, forming relationships and building independent lives. Each stage involves both gain and loss.

When caregivers support these transitions well enough, children gradually learn that difference and loss is manageable. We do not have to be identical or merged to stay connected. Healthy relationships become more like Venn diagrams - interdependent but distinct.

Therapy also recognises that strong emotions can reactivate earlier experiences. Encounters with difference in adulthood may unconsciously trigger early feelings of separation or loss that were first experienced before we had language to describe them. What looks like a disagreement in the present can sometimes carry echoes of much earlier emotional experiences.

Evolutionary Roots of Tribal Thinking

Another reason difference can feel threatening lies in human evolution. For most of our history, belonging to a group was essential for survival. Being cast out of the tribe could mean exposure, starvation or violence. Our brains therefore evolved to make rapid judgments about who belonged and who did not.

A striking illustration comes from the discovery of Ötzi the Iceman. Found by hikers in the Italian Alps in 1991, Ötzi lived around 3200 BCE. Analysis of his body revealed a life marked by illness, injury and ultimately death from an arrow wound.
Archaeological evidence suggests that in prehistoric societies as many as one in three men may have died violently. By comparison, modern societies in Europe and North America experience far lower rates of violent death. Yet our nervous systems still carry the ancient mechanisms designed to detect threat quickly.

In other words, even in relatively safe societies we may still react to difference as if survival were at stake.

The Rise of Black-and-White Thinking

When our threat system is activated, the body moves into the familiar “fight, flight, freeze or fawn” response. Stress hormones such as adrenaline and cortisol flood the body, heart rate increases and attention narrows.

At the same time our thinking changes. The emotional older limbic brain becomes dominant while the newer more rational prefrontal cortex becomes less active. This response is excellent for escaping physical danger but less helpful when navigating complex social issues.

Under threat, thinking becomes simplified. Psychologists describe this as “cognitive errors”: generalising, catastrophising, blaming or assuming certainty. Statements such as “they are wrong and we are right” or “they are idiots and we know best” become more common. Nuance disappears and positions harden.

Social Media and Public Debate

Modern communication environments may intensify this pattern. Social media platforms often reward certainty, speed and outrage rather than reflection and nuance. Complex issues are easily reduced to moral binaries.

The cancelling of J. K. Rowling in response to her tweets and views about the trans/women debate illustrates how quickly disagreements can escalate into hostility and personal attack. Regardless of where one stands on the issue, the intensity of reaction suggests that broader anxieties and conflicts may be playing out through symbolic figures.

Similarly, conflicts involving Israel and Palestine show how competing narratives can harden into polarised positions. When people feel existentially threatened, black-and-white thinking intensifies and dialogue becomes extremely difficult whilst the suffering continues.

Scarcity and Heightened Threat

Another factor may be the sense of global uncertainty many people experience today. Constant exposure to news about war, climate change, economic pressures and population growth can create a feeling of scarcity and insecurity.

Scarcity tends to increase stress and anxiety. When people feel under pressure, the nervous system becomes more vigilant and reactive. In this state, difference may feel not simply uncomfortable but potentially dangerous.

Yet for many of us this sense of threat is psychological rather than immediate. Living in a constant state of alarm is rarely helpful and makes meaningful dialogue or collaboration even harder.

Returning to the Window of Tolerance

A useful concept for understanding these reactions is the “window of tolerance,” developed by psychiatrist Dan Siegel. Within this window our nervous system is regulated enough for us to think clearly, listen and remain curious.

Outside this window we move into hyper-arousal (anxious, angry and reactive) or hypo-arousal (shut down or withdrawn). When discussions about difference push us into either state, productive conversation becomes very difficult.

Mindfulness practices can help people notice when they have moved outside their window of tolerance. Paying attention to physical cues - such as a racing heart or tension - creates the opportunity to pause and regulate our response. Once calmer, the prefrontal cortex becomes more active again, allowing more thoughtful engagement.

Conversations That Work

In mediation and conflict-resolution work, productive conversations usually begin with creating psychological safety. Participants are reminded that disagreement does not have to be a zero-sum game and that shared humanity remains.
Conversations then follow a simple structure:

Ask open questions to explore the other person’s perspective, beliefs and values.
Listen carefully and summarise what has been heard to check understanding.
Identify areas of agreement and disagreement before exploring possible ways forward.

When conversations are guided by curiosity, respect, compassion and the principle of unconditional positive regard developed by Carl Rogers, they can be surprisingly transformative. Even deeply entrenched conflicts sometimes soften once people feel genuinely safe and heard.

Holding Multiple Perspectives

Many conflicts reveal an important truth: behind opposing positions often lie similar human experiences. Fear, grief, trauma and the desire for safety frequently exist on all sides.

Organisations such as Solutions Not Sides work with schools to explore multiple perspectives on the Israeli Palestinian Conflict. By presenting different narratives and encouraging critical thinking, they model an alternative to polarised debate.

The opposite of black-and-white thinking is not indifference but the ability to hold multiple perspectives at once. Developing that capacity may be one of the most important skills for navigating difference in an increasingly complex world and is one that therapy can foster.
