Why Making Friends in College Affects Your Grades More Than You Think

According to 2024 research from the American College Health Association, 67% of college students report feeling lonely during their first semester. Two thirds. And that number does not capture the students who feel functionally isolated mid-semester, or the ones who have acquaintances everywhere and still feel like nobody actually knows them. Sallie

College loneliness is treated as an emotional problem. Get out more, join clubs, say yes to things. The advice is not wrong, exactly, but it misses something the research is pretty clear about: loneliness in college is also an academic problem. The connection between social belonging and academic performance is not soft or indirect. It shows up in GPA, in persistence through hard semesters, and in whether students finish their degree at all.

This is not about needing to be social to be successful. Plenty of introverted students thrive. It is about the specific things that peer connection provides academically, and what students lose when it is absent.

What the Research Actually Shows

Janice McCabe, a sociologist at Dartmouth who spent years studying how friendships form and function on college campuses, published findings in her book Connecting in College that cut against the usual framing. Friendship networks positively and negatively impact students' academic performance, social experiences, and life after college. And they do so differently across racial, gender, and class backgrounds. ReviewJane

The nuance matters. Not all friendships help academically. A tight friend group that mostly socialises and avoids academic conversation can actually pull performance down. But friendships built around shared academic goals, studying together, and mutual accountability consistently lift performance for everyone in them.

In the book Connecting in College, a study among college students reveals that a close group of friends provided academic motivation and social support. They did well by studying together, checking in with each other when facing important assignments, and celebrating each other's achievements. Shorelight

A systematic review and meta-analysis published in PLOS ONE in 2024 found that academic achievement and motivation positively correlate with belonging to a peer group. The mechanism is not complicated. When you feel like you belong somewhere, academic work becomes something you do as part of a community rather than a solitary grind with unclear stakes. The feedback loop of peer motivation, shared norms around effort, and social accountability all pull performance upward. Birmingham City University

The flip side: Friendships can sometimes lead to distractions in class. Students might engage in conversations or activities with friends during classes, causing disruptions in their focus. The kind of friends matters as much as having them. PubMed

Why College Loneliness Is Harder Than It Looks

Most students arrive at college expecting the social side to sort itself out. You are surrounded by thousands of people your age. How hard can it be?

Harder than it looks, it turns out. The social conditions that made friendship easy in earlier life, mainly proximity, repetition, and no choice about it, do not automatically reproduce in college. In high school, you sat next to the same people for years. In college, class compositions change every semester. Dorm floors have high turnover. Lecture halls of 300 people are anonymous by design.

Successful social connection in college depends on putting yourself in situations where repeated positive interactions can occur, following what social psychologists call the "mere exposure effect." You do not become friends with someone after one good conversation. You become friends through repeated low-stakes contact over time. The students who build strong social networks in college are not necessarily more charming than the ones who do not. They are more frequently in the same place as the same people. Sallie

This is the structural reason study groups and academic partnerships produce friendships so reliably. They create the repetition that friendship requires without demanding social performance. You show up, you work, you talk about the material, you leave. Do that enough times with the same person and you have built something real, almost by accident.

There is also the social anxiety piece. Social anxiety affects approximately 15% of college students according to the Anxiety and Depression Association of America, making it a significant barrier to forming friendships. Students with social anxiety often avoid social situations, creating a cycle where lack of practice reinforces the anxiety. For these students, the low-pressure structure of a study session is often more accessible than a party or a club social. The task gives everyone somewhere to put their attention. The conversation emerges from shared work rather than requiring someone to perform sociability on command. Sallie

The Specific Loneliness of Transfer and Commuter Students

Not all college students navigate this the same way. Transfer students and commuter students face a particular version of the problem.

Transfer students arrive into social ecosystems that have already been forming for a year or two. The first-year bonding experiences, the awkward-but-shared disorientation of orientation week, the random friendships formed in freshman dorms, all of that has happened without them. Friendships on campus have calcified somewhat, and breaking into existing groups is harder than forming them from scratch.

Commuter students face a different version: they are on campus for class, then they leave. The casual hallway conversations, the spontaneous dinner invitations, the study sessions that form after lectures, most of those opportunities require being around. When you are not around, you miss them. And because you are not struggling with homesickness or dorm life, people sometimes assume you are fine, even when you are significantly more isolated than residential students.

For both groups, intentional structures for connection matter more than for residential students who have built-in proximity. Waiting for social connection to happen organically is a longer wait when you are not sleeping two floors below potential friends.

What Actually Works: Building Social Connection That Helps Your Grades

Find recurring, low-stakes contexts. The best friendships in college form in settings where you keep showing up. A weekly study group, a recurring lab section, a club that meets consistently, a recurring virtual study session. The repetition does the relationship-building work. You do not need to be especially outgoing. You need to keep showing up.

Prioritise academic social contexts over purely social ones. This sounds counterintuitive for an article about making friends, but the research backs it. Upper-level courses in your major provide natural opportunities to connect with students who share your academic interests and career goals. These relationships often develop into strong friendships because they are built on mutual respect for shared intellectual pursuits. Study groups and research projects create regular interaction that serves both purposes. You get the academic accountability and the social connection at the same time. Sallie

Do not wait until you feel ready to be social. The instinct when feeling lonely or anxious is to wait until you feel better before reaching out. That instinct makes the isolation worse. Social connection improves mood, not the other way around. The research on the mere exposure effect means that the first few interactions with someone do not need to be particularly warm or memorable. They just need to happen.

Be specific about what you are asking for. "We should study together sometime" produces almost nothing. "I'm working on the chapter 4 problem sets Thursday at 2, want to join?" produces a plan. Specific, time-bound invitations are far more likely to result in actual interaction than vague social intentions, especially with people who are also slightly anxious about imposing.

Use platforms built for academic connection. This is where the online world genuinely helps. Academync matches students based on academic goals, schedule, and subject focus. You are not cold-messaging a stranger asking if they want to study. You are connecting with someone who has already indicated they want what you want. The matching removes the social awkwardness of initiating and gives both people a clear shared context from the start. For commuter students, transfer students, online students, or anyone who finds in-person social initiation difficult, this kind of structured matching is often the most realistic path to building academic peer relationships.

The Difference Between Knowing People and Having Academic Community

There is a version of college social life that looks fine from the outside but provides very little of what actually helps academically. You know a lot of people. You have people to sit with at lunch. But nobody is checking in when you miss class. Nobody notices when you are struggling. Nobody is raising the academic standard around you because nobody in your circle is particularly focused on academic goals.

McCabe's research in Connecting in College identified this distinction clearly. Three key types of friendship networks exist among college students: close-knitters, compartmentalizers, and samplers, each with different advantages and disadvantages for the academic and social lives of students. Close-knitters have one dense friend group that provides strong support but sometimes creates insularity. Samplers have loose connections across many groups, which provides breadth but less depth. Compartmentalizers maintain separate social and academic networks, which allows them to calibrate the relationship between social life and academic performance more deliberately. ScienceDirect

The takeaway is not that one type is superior. It is that having at least one relationship specifically built around academic engagement produces outcomes that general social connection does not. A friend who holds you accountable to showing up to study, who notices when your focus drops, who you feel mild social obligation toward when you consider skipping a session, is different from a friend who you eat dinner with.

Both matter. The second kind is what most students are missing.

Loneliness and the Drop-Out Connection

The stakes here are worth naming directly. Social isolation in college is not just uncomfortable. It predicts dropout.

There is a strong correlation between a lack of involvement in extracurricular activities and dropout rates. Students that establish a healthy work-life balance early on have better engagement and success rates. University of Cincinnati

When students feel they do not belong at their institution, the academic motivation to push through hard semesters weakens. A bad exam grade lands differently when you have peer support than when you are managing it alone. A hard semester feels different when you are surrounded by people navigating the same thing than when you are watching everyone else appear to cope fine while you struggle silently.

The antidote is not telling lonely students to cheer up. It is building the structural conditions for repeated, low-stakes academic contact with people who share their goals. That is what produces belonging. And belonging, the research is consistent on this, is what keeps students in school.

FAQs

Q: Why is it so hard to make friends in college even on a full campus? Because the conditions that make friendship easy in earlier life, mainly forced proximity, repetition, and no exit option, do not automatically exist in college. Class compositions change every semester, lecture halls are anonymous, and dorm communities turn over. Friendship research shows that most relationships form through repeated low-stakes contact over time, not through single impressive interactions. Students who build strong networks do so by consistently showing up in the same spaces as the same people, not by being unusually socially skilled.

Q: Does loneliness in college actually affect your grades? Yes, through several mechanisms. Socially isolated students lose the peer accountability, academic motivation, and emotional support that peer groups provide. They are also more likely to skip class when struggling, avoid asking for help, and drop out during hard semesters. Research consistently finds that belonging to an academically-oriented peer group positively predicts GPA and academic persistence. The effect is not small. Having even one academically-focused peer relationship changes how students navigate difficulty.

Q: How can I make friends in college if I'm a transfer or commuter student? The social infrastructure that residential first-year students benefit from, dorm life, orientation week bonding, shared disorientation, is largely absent for transfer and commuter students. Intentional structures matter more for these groups. Study groups, recurring club meetings, and platforms that match students for academic connection give you the repetition that friendship requires without depending on proximity. Being specific about invitations (time, place, task) rather than vague about social intentions also closes significantly more social gaps.

Q: Can study groups help with college loneliness? Yes, and this is one of the most underappreciated functions of academic study partnerships. Study groups create the repeated, low-stakes contact that social psychology identifies as the engine of friendship formation. You show up, you work together, you talk about the material and eventually about other things, and after enough sessions you have built something real. For students with social anxiety, the task-focused structure of a study session is often more accessible than a social event because the shared work gives everyone a focus beyond performing sociability. Platforms like Academync make it easier to find a consistent study partner by handling the matching, so the social initiation barrier is lower.

Q: How do I find friends in college who actually care about studying? This is the real question, and it is a good one. Casual social spaces, parties, dining halls, clubs based on non-academic interests, tend to produce friendships that are warm but not academically motivating. Academic contexts, study groups, upper-level classes in your major, research projects, lab sections, produce friendships built on shared intellectual investment. These relationships tend to raise academic performance for everyone in them because the shared norms include taking coursework seriously. Academync matches students specifically on academic goals and study schedules, which front-loads the compatibility that usually takes a semester of trial and error to discover.

Q: What if I'm an introvert who finds it exhausting to build social connections? Introversion does not mean you need less connection. It usually means you need lower-intensity, higher-quality contact rather than high-stimulation social events. One consistent study partner you meet virtually each week is more sustainable and often more academically valuable than a large rotating friend group. The task-focused structure of a study session suits introverts well precisely because it gives the interaction a purpose and a natural end point. You do not have to perform sociability. You just have to show up and do the work alongside someone else.

The easiest way to find academically-focused peers is to start with the academic context. Academync matches you with students who share your goals and schedule, so the social awkwardness of finding your people is already handled before you show up.
