“Oh my god, the test grades dropped! What’d you get?” is likely the most common question I hear on a day-to-day basis at Lexington High School. But why is this question so common? I believe it is linked to the concept of “social comparison,” an idea deeply prevalent in our everyday lives. As humans, we tend to compare ourselves to others subconsciously: who do we see as better than us, and who do we see as worse?
At LHS, this tendency often extends far beyond test grades. Conversations in hallways and cafeterias often shift toward college-related metrics: SAT scores, GPAs, and top schools. I’ve been asked questions like “What was your SAT?” and “Did ED results come back yet?” in moments that were meant to be casual but instead stressed me more than they should have. Even when no judgment was intended, these interactions trigger internal comparisons that reframe our self-worth around numbers.
Neuroscience can explain why these moments feel so emotionally charged. Research shows that social comparison activates the brain’s reward and threat system. When we perceive ourselves as doing better than others, the ventral striatum, an area associated with reward and dopamine release, activates, reinforcing comparison as a behavior. However, when we perceive ourselves as “worse off,” the amygdala will kick-start feelings of fear and threat. This means that a simple question about grades or college plans can register in the brain not only as information, but also as a potential social threat.
Additionally, social comparison heavily involves the medial prefrontal cortex (mPFC), a region associated with self-referential thinking—basically how we evaluate ourselves. This region becomes more active when we compare our abilities or status to others, indicating that comparison directly alters our self-concept in real time.
For adolescents in particular, this neural response is amplified. During the teenage years, the brain’s reward system develops more rapidly than the prefrontal regions responsible for emotional regulation and perspective-taking. This imbalance makes teens especially sensitive to social evaluation. Thus, in an academically competitive environment like LHS, constant exposure to peer comparisons can heighten stress and anxiety, even among high-achieving students. I’ve seen classmates second-guess their abilities or feel discouraged, not because they were underperforming, but because they were surrounded by peers who seemed like they were doing “more.”
Over time, this pattern of comparison can condition the brain to associate academic conversations with stress. Instead of feeling curiosity or motivation, the body reacts with tension. Ironically, this chronic stress can impair memory, focus, and learning, making it harder to perform well academically and reinforcing the very insecurities that comparison creates.
Understanding the neuroscience behind social comparison has made me more aware of how deeply these habits are wired into us. While comparison may be natural, it doesn’t have to dictate our sense of worth. By shifting attention away from external metrics and towards personal progress, we can quiet the brain’s threat response and create a healthier academic environment, one where success is defined as more than rankings against each other, but as how we grow.
