Psychology says you secretly compare yourself with old classmates and it is not jealousy

You may not think about your old classmates every day. But one social media update, a reunion photograph or a random announcement about someone's promotion, marriage, business or new home can suddenly make you wonder: Where am I compared with them?

Psychology suggests this reaction is not necessarily about jealousy. It may be a normal consequence of social comparison, a process through which people evaluate themselves by looking at others. And old classmates can be particularly powerful comparison targets because they once occupied a similar starting point in your life.

Psychology Says Social Comparison Helps Us Judge Where We Stand

The idea goes back to psychologist Leon Festinger, who proposed Social Comparison Theory in 1954. His argument was that people have a basic tendency to evaluate their opinions and abilities, and when objective standards are unavailable, they often look at other people for information. That makes an old classmate an unusually convenient psychological reference point.


Imagine two students who sat in the same classroom, had similar teachers and roughly the same number of years ahead of them. Twenty years later, one becomes a successful entrepreneur while the other is working in a completely different field. Seeing that person's achievement may automatically trigger a comparison because the brain already has a shared reference point.

Research by Jerry Suls, René Martin and Ladd Wheeler describes social comparison as a way people obtain information about themselves, particularly when evaluating abilities and opinions. Similarity between the comparison target and the person making the comparison can make that information especially useful.

Old Classmates Feel Like “People Like Me”

This is one reason an old classmate can affect you more than a random successful stranger. You may see a celebrity buying a luxury house and think, Good for them. But when someone who sat beside you in mathematics class buys one, the psychological response can be different. The comparison feels more personally relevant.

Psychologist Thomas Mussweiler has studied how comparison targets influence self-evaluation through his Selective Accessibility Model. The basic idea is that once we compare ourselves with another person, our minds selectively bring certain self-related information to the forefront. If we focus on similarities, we may feel closer to the other person; if we focus on differences, we may experience a stronger sense of distance.

So an old classmate's promotion might make you remember your own achievements, or make you notice everything you believe you have not accomplished.

Why Their Success Can Make You Feel “Behind”

Psychologists distinguish between upward and downward social comparisons. An upward comparison happens when you compare yourself with someone you perceive as doing better in an area that matters to you. This can be uncomfortable, but it is not always harmful. Sometimes it provides motivation or information about what might be possible.

A large meta-analysis of more than six decades of social-comparison research found that people often choose upward comparison targets, while the emotional and self-evaluative consequences can vary considerably depending on the situation and the person.

This explains why an old classmate's success might produce two reactions at once: I'm genuinely happy for them and What have I done with my own life? Those feelings can coexist.

Social Media Makes Old-Classmate Comparisons Easier

Social media adds another layer because it constantly exposes people to carefully selected information about others.

You rarely see the full story of an old classmate's life. You see the promotion, holiday, wedding, new business or award. Your brain then compares that visible achievement with your own much more complete and complicated reality. That can create a distorted comparison: their highlight versus your behind-the-scenes life.

Research on social comparison also suggests that comparisons can occur surprisingly automatically. Studies by Mussweiler and colleagues have found that comparison processes can be triggered even when people have not deliberately chosen a comparison target.

This means you do not necessarily have to consciously think, I am comparing myself with my former classmate. Your mind may simply begin evaluating your own position.

Sometimes the Real Comparison Is With Your Younger Self

There is another reason old classmates can feel strangely powerful: they remind you of who you were expected to become.

Seeing someone from school can reactivate memories of ambitions, expectations and possibilities from an earlier period of life. You may not actually want their career or lifestyle. Their progress may simply remind you of your own unfinished plans.

For example, an old classmate becoming a doctor may not make you want to become a doctor. Instead, it might remind you that you once wanted to pursue a completely different career. In that sense, the comparison may be less about them and more about your own perceived life trajectory.

Comparing Yourself With Old Classmates Is Not Automatically Bad

Social comparison becomes problematic when it repeatedly turns into harsh self-judgment, envy, regret or a belief that there is one correct timeline for everyone.

But comparison can also provide useful information. It can reveal what you value, what goals you have abandoned and what achievements matter to you. The important question may therefore not be, Why am I comparing myself with them? It may be: What is this comparison telling me about myself?

An old classmate's life is not a measurement of your worth. Psychology suggests that comparison is one of the ways humans make sense of themselves, but the person you compare yourself with does not determine where you should be.

FAQs

Why do I compare myself with old classmates?

Old classmates can become powerful comparison targets because they share part of your history and may represent a similar starting point. Their achievements can therefore provide a psychologically meaningful reference point for evaluating your own life.

Is comparing yourself with classmates a sign of jealousy?

Not necessarily. Social comparison can involve curiosity, motivation, self-evaluation, admiration or regret. Feeling uncomfortable after seeing someone else's success does not automatically mean you are jealous.
