For centuries, people have understood social class as more than a number on a paycheck. It can shape where someone lives, which schools they attend, the networks they enter, the institutions they trust and the cultural signals they learn to recognize. Yet psychology began examining social class as a sustained topic only about three decades ago. Since then, researchers have accumulated an expanding but sometimes confusing body of evidence about how class influences thought, emotion and behavior. A new review argues that some of these contradictions may not be true disagreements at all. Instead, they may arise because scientists have been using different definitions of social class while treating them as if they measured the same thing.
The review, published in Nature Reviews Psychology, examines the major ways researchers have attempted to define and measure social class. Social class is commonly linked to access to material, social and cultural capital, but these forms of access are not identical. Material capital includes income, wealth and the ability to obtain goods and services. Social capital refers to useful relationships, networks and institutional connections. Cultural capital includes education, knowledge, language styles, tastes and behaviors that may be valued by influential institutions. A person can possess a high level of one form of capital without possessing the others, creating very different psychological experiences under the broad label of “high” or “low” social class.
One of the review’s central fault lines is the distinction between objective and subjective social class. Objective measures rely on externally observable indicators such as income, educational attainment, occupation or neighborhood characteristics. These measures allow researchers to compare participants using standardized information and can reveal how resources are distributed across a population. Subjective social class, by contrast, reflects how people perceive their own position relative to others. It is often measured by asking individuals to place themselves on a social ladder, with people at the top understood to have greater access to money, education and respected occupations than those at the bottom. Although objective and subjective class can be related, they may diverge sharply.
A person’s subjective position is shaped not only by their absolute resources but also by the social groups they use for comparison. Someone with a stable income and university education may feel financially insecure when surrounded by much wealthier people. Another person with fewer material resources may feel relatively advantaged within a community where their education, occupation or family connections provide status. These perceptions can have psychological consequences of their own. Feeling deprived, secure, respected or excluded may influence stress, expectations and social behavior even when two people have similar objective incomes. Conversely, objective resources can affect health, opportunity and daily constraints regardless of how individuals interpret their position. Treating the two measures as interchangeable can therefore obscure important mechanisms.
A second distinction separates social rank from social class as culture. Rank describes relative standing in a hierarchy: who has more resources, influence, prestige or control than whom. Cultural approaches focus instead on learned patterns of behavior and meaning associated with a person’s social background. These patterns can include communication styles, preferences, norms surrounding independence or interdependence, and assumptions about how institutions operate. Two people may occupy a similar economic rank but differ in cultural history, while people from different economic positions may share cultural practices through migration, education, professional environments or community life. Rank and culture can overlap, but they answer different questions about how social class becomes psychologically meaningful.
Rank-based explanations often emphasize power, control and access to valued resources. People who occupy higher positions may have greater freedom to shape their surroundings, obtain assistance and pursue long-term goals. Lower social rank may expose individuals to greater uncertainty, dependence on others and sensitivity to external constraints. These conditions can influence attention, decision-making and responses to risk. Cultural explanations, meanwhile, examine how people learn to navigate social environments. For example, a person raised in a setting where institutions are reliable may develop different expectations about authority and opportunity than someone raised in a setting where institutions have been unpredictable or exclusionary. The resulting psychological patterns cannot automatically be attributed to rank alone.
The review also highlights the difference between adult, or current, social class and childhood social class. Current class captures people’s present circumstances, including their income, education, occupation and social environment. Childhood class refers to the conditions in which people developed, often measured through parental education, family income, neighborhood characteristics or the occupation of caregivers. These two forms of class can remain connected across the life course, but they can also separate. Someone may grow up with limited resources and later achieve economic security, while another person may experience downward mobility after being raised in a wealthy family. Each history may leave distinct psychological traces.
Childhood conditions can influence development through multiple pathways. Early access to nutrition, stable housing, educational resources and supportive networks may affect cognitive development and future opportunities. Family environments can also transmit expectations, habits and cultural knowledge that continue to shape behavior after material circumstances change. At the same time, current class determines the constraints and possibilities people face in adulthood. A person’s present access to healthcare, employment security or social influence may affect stress and decision-making even if their early life was highly advantaged or disadvantaged. Comparing childhood and adult class can therefore help researchers distinguish the effects of developmental history from those of immediate circumstances.
These three contrasts are not independent. Subjective class may reflect both current material conditions and memories of childhood, while perceptions of rank can be shaped by cultural norms about money, education and respectability. A person’s current occupation may increase objective status without changing the cultural practices learned during childhood. Likewise, cultural background can influence how someone interprets their place on a social ladder, making subjective class partly a product of social comparison and identity. Because the dimensions overlap, a study that reports an effect of “social class” may not reveal whether the result was driven by economic resources, perceived rank, cultural learning, family history or a combination of these factors.
The review’s broader message is not that one definition of social class is correct and the others are flawed. Each approach has generated valuable insights into how inequality is experienced and reproduced. The scientific challenge is to identify which dimension matters for a particular psychological outcome and why. Future studies may need to measure several forms of class simultaneously, distinguish mechanisms more carefully and follow people across different stages of life. Doing so could clarify why apparently similar studies sometimes produce conflicting findings. More precise definitions would also make social-class research more useful for understanding how economic inequality, cultural experience and social hierarchy shape the mind.
Subject of Research: The psychological dimensions and measurement of social class, including subjective versus objective class, rank versus culture, and current adult versus childhood social class.
