Most People Think Their Friends Are Less Cynical Than They Really Are

Most people believe their friends see the world more charitably than they actually do, and that cheerful illusion might be one of the quiet engines keeping friendships alive.

A new peer-reviewed study published in Evolution and Human Behavior finds that people consistently underestimate how cynical their friends are, rating them as more trusting and optimistic about human nature than those friends rate themselves. Psychologist William J. Chopik of Michigan State University, who conducted the research, argues this isn’t simply a blind spot. It may reflect a possible adaptive tradeoff in friendship, a mental softening that keeps cooperation running smoothly by muting awareness of how much the people we care about actually distrust other people.

Cynicism, as defined in the study, is not mere pessimism. It refers specifically to a mistrust of others and a belief that people are primarily motivated by self-interest. Someone high in cynicism assumes others will lie, cheat, or take advantage when it suits them. That kind of worldview, research has consistently shown, carries real costs: higher mortality rates, weaker social ties, and a tendency to create self-fulfilling cycles of distrust that push people further apart. And yet, having some capacity to detect cynicism in others is also useful, helping people identify who might betray them and making it a valuable social radar.

How the Study Measured Cynicism Between Friends

Chopik recruited 173 friend pairs, totaling 346 participants, through Michigan State University between September 2024 and May 2025. Each person filled out a survey rating their own level of cynicism and then rating their friend’s cynicism, using five questions drawn from the Cook-Medley Hostility Inventory, a well-established psychological measure. A sample question: “I think most people would lie in order to get ahead.” Participants responded on a 6-point scale ranging from “strongly disagree” to “strongly agree,” answering about themselves and then answering the same question framed around their friend by name.

Participants were young, on average around 19 years old, and had known each other for roughly four and a half years, though friendship lengths ranged from as little as three months to as long as 18 years. The sample was predominantly women (70%) and white (72%), with most friend pairs having met through school. To analyze the data, Chopik used what’s called the Truth and Bias Model, a statistical framework that separates how much a person’s judgment of someone else reflects reality (tracking accuracy) from how much it reflects bias or self-projection.

What Friends Actually Think, and Where They’re Wrong

Three distinct patterns emerged from the analysis. First, and most consistently, people underestimated how cynical their friends were. On average, participants rated their friends as less distrustful than those friends reported being themselves, a systematic positivity bias across the board. Second, people projected their own level of cynicism onto their friends. Highly cynical participants tended to assume their friends were also highly cynical, while those low in cynicism assumed the same of their friends. Third, there was a modest degree of genuine accuracy: people’s judgments of their friends tracked somewhat with how those friends actually described themselves, though the alignment was limited.

Chopik explored whether factors like how long two people had been friends, how close they were, or how much they trusted each other would change any of these patterns. With one notable exception, the answer was no. Neither closeness nor trust had much influence on accuracy or bias. The lone exception involved friendship length: people in newer friendships underestimated their friends’ cynicism even more strongly than those in longer-standing ones. Among newer friends, the positivity bias was particularly pronounced. Among long-term friends, the bias was still present but more tempered.

Why a Rosy Blind Spot May Actually Help Friendships Survive

At first glance, consistently misreading a friend’s character seems like it would cause problems. And it can: trusting someone who harbors deep distrust of others is a real vulnerability. But Chopik’s analysis points toward a different read on the situation. Seeing a friend as less cynical than they are may work as a kind of social lubricant. It softens perceptions of antagonism, reduces unnecessary conflict, and reinforces the cooperative foundation that makes friendships worth maintaining in the first place.

From an evolutionary standpoint, this makes a certain kind of sense. Friendships function partly as alliances, networks of mutual support that historically helped people navigate competition, danger, and resource scarcity. Maintaining those alliances requires some degree of assuming the best about the people in them. “These findings suggest that people view their friends both accurately and positively, balancing the need to detect self-interest with the relational benefits of maintaining trust and similarity,” Chopik writes in the paper.

At the same time, the modest accuracy people showed in judging friends’ cynicism suggests the system isn’t entirely blind. People are getting some real signal about who their friends are. Cynicism may simply be harder to read than more visible personality traits like extroversion, which tend to surface more readily in day-to-day behavior.

It’s worth noting what the study did not find. Despite what many people might assume, being closer to a friend or trusting them more didn’t make someone better at reading that friend’s cynicism, nor did it make someone more likely to view them through rose-colored glasses. The expectation that deeper knowledge of a friend would bring clearer-eyed perception largely didn’t hold up here.

That said, the finding about newer friendships does suggest something worth watching: the social illusions that smooth early friendships may thin out over time, as people accumulate more evidence about who their friends really are.

Friendship, in other words, may run partly on managed ignorance, a willed optimism about the people we’ve chosen to keep close, calibrated just enough to keep the relationship intact without losing sight of who they actually are.
