Overview: This sample shows how to plan and write an undergraduate argumentative essay. It opens with a worked outline example that maps the thesis, the job of each paragraph and the evidence behind it, then presents the full essay arguing that heavy, passive and poorly regulated social media use is a modifiable risk factor for adolescent mental health. It is provided purely as a structure-first learning reference, with Harvard (Cite Them Right) referencing.
An argumentative essay is won or lost at the planning stage. Before drafting a single paragraph, an experienced writer settles three things: the exact claim being made (the thesis), the reasons that support it, and the evidence attached to each reason. A clear plan prevents the two most common undergraduate problems — a thesis that drifts or disappears, and body paragraphs that describe a topic without actually arguing for anything. The outline below is offered as a template. It takes the debate question ‘Does social media harm the mental health of young people?’ and converts it into a logical skeleton. Once that skeleton holds together, drafting becomes a matter of expanding each line into a paragraph, so the finished essay that follows can be read directly against the plan.
Working thesis: Although social media delivers real social and informational benefits, the balance of evidence indicates that heavy, passive and poorly regulated use is associated with poorer adolescent mental health; it should therefore be treated as a modifiable risk factor to be managed through design, regulation and education, rather than as a harmless feature of modern life.
The skeleton below lists each section in order and records the single point it must deliver. Note that every body paragraph is built from a claim (its topic sentence), evidence (the research cited) and analysis (why that evidence supports the thesis), and that one whole section is reserved for the opposing view.
The same plan can be summarised as a paragraph-by-paragraph map, which is the most useful form to keep beside you while drafting.
| Paragraph | Job in the argument | Topic sentence (in brief) |
|---|---|---|
| Introduction | Frame and state thesis | A near-universal technology deserves scrutiny, not assumption. |
| Body 1 | Establish the scale | The dose is large and increasingly passive. |
| Body 2 | Weigh the evidence | Associations are small but real and partly causal. |
| Body 3 | Explain the mechanism | Comparison, displacement, design and harassment do the damage. |
| Body 4 | Concede and rebut | Benefits are real, but average effects hide concentrated harm. |
| Body 5 | Apply the argument | A modifiable risk calls for design, regulation and education. |
| Conclusion | Resolve | The problem is real, bounded and solvable. |
Few technologies have been adopted as quickly, or as completely, as social media. Within a single generation, platforms built around continuous sharing and comparison have become the default environment in which adolescents socialise, learn and form a sense of who they are. That ubiquity has turned a once-marginal question into an urgent one for psychologists, educators and policymakers alike: is this environment good for young minds? This essay argues that, although social media delivers genuine social and informational benefits, the balance of evidence indicates that heavy, passive and poorly regulated use is associated with poorer mental health among adolescents, and that it should therefore be treated as a modifiable risk factor rather than a harmless feature of modern life. The discussion first establishes the scale of adolescent use, then weighs the empirical evidence and its limits, examines the mechanisms through which harm may occur, addresses the strongest counter-arguments, and finally considers what a proportionate response should look like.
The first reason to take the question seriously is simply the dose. Among adolescents in high-income countries, ownership of a smartphone is close to universal, and the typical teenager now spends several hours each day on networked platforms (boyd, 2014; Odgers and Jensen, 2020). This exposure is concentrated in precisely the years during which identity, peer relationships and emotional regulation are still forming, which makes adolescence a period of unusual sensitivity to any sustained environmental influence. Importantly, not all of this time is equivalent. Researchers increasingly distinguish between active use — messaging friends, sharing creative work or organising offline activity — and passive use, in which a person scrolls through an endless feed of other people’s curated lives without interacting at all (Verduyn et al., 2017). The weight of ordinary use has drifted towards the passive end, as algorithmic feeds are optimised to hold attention rather than to prompt participation. The implication for the argument is straightforward: when a behaviour is practised for three hours a day, every day, throughout the most formative years of life, even a small effect per session can accumulate into a meaningful influence on mood and self-image. A dose that large deserves scrutiny regardless of whether any single session feels harmful at the time.
The empirical picture is genuinely mixed, and being honest about that mix strengthens the argument rather than weakening it. Systematic reviews of adolescent populations report consistent, if modest, associations between heavier social media use and symptoms of depression, anxiety and psychological distress (Keles, McCrae and Grealish, 2020). Large analyses of representative datasets confirm that the relationship is real but small, often accounting for only a few per cent of the variation in wellbeing — an effect size that one influential comparison likened to something as mundane as wearing glasses (Orben and Przybylski, 2019). Critics rightly note that most of this research is correlational: an unhappy teenager may turn to a phone for comfort just as readily as a phone may make a teenager unhappy, and the arrow of cause could point either way. Yet several strands of evidence point towards a genuine causal contribution. Dose–response patterns, in which measured distress rises with hours of use, are difficult to explain by reverse causation alone (Twenge and Campbell, 2018). Studies that isolate passive use, and those that track perceived loneliness and social isolation over time, report associations that persist after prior mental health is controlled for (Primack et al., 2017; Vannucci, Flannery and Ohannessian, 2017). A smaller body of experimental work, in which volunteers are randomly assigned to reduce or suspend their use for a defined period, has likewise reported modest improvements in mood and reductions in loneliness across several trials; this is precisely the design best placed to establish the direction of cause, even though the effects remain small and the findings are not unanimous. The reasonable conclusion is not that social media is a catastrophe, but that it is a plausible and partly causal contributor to a wider decline in adolescent wellbeing: small at the level of the individual, yet substantial once multiplied across an entire generation.
If an association exists, the next question is how it is produced, and here at least four mechanisms are well supported. Crucially, each is a feature of design rather than an accident of use. The first is social comparison. Feeds present a relentless stream of idealised images — holidays, bodies, achievements — against which ordinary life inevitably compares badly, fuelling envy and lowered self-esteem, an effect reported most strongly among adolescent girls (Royal Society for Public Health, 2017; Appel, Marker and Gnambs, 2020). The second is displacement: hours spent scrolling are hours not spent sleeping, exercising or meeting friends in person, and each of those displaced activities is itself protective of mental health, so the harm is partly a matter of what social media crowds out. The third is the architecture of engagement. Infinite scroll, autoplay, variable notifications and visible ‘like’ counts are engineered to maximise time on the platform, borrowing directly from the psychology of intermittent reinforcement; the user’s attention is the product being sold, and their wellbeing is simply not the design objective. The fourth is the migration of social cruelty online, where harassment can follow a young person home, operate anonymously and reach an audience of thousands within minutes. None of these mechanisms requires us to assume that teenagers are passive or foolish. Together they describe an environment in which the ordinary, rational use of an attractive product carries a predictable psychological cost.
A fair argument must engage honestly with the benefits of social media, which are substantial and should not be dismissed. For geographically isolated, disabled or marginalised young people — including LGBTQ+ adolescents who may lack accepting communities offline — these platforms can provide identity-affirming connection and access to support that would otherwise be out of reach. For many young people the online world is not a replacement for social life but an extension of it, so blanket withdrawal of access can itself carry a genuine social cost. These platforms also democratise creativity, host mental-health information and allow friendships to be maintained across distance. Sceptics also raise two methodologically serious points. First, the measured effects are small and the literature is noisy; some studies tracking wellbeing across time and across countries find little evidence that the rise of these platforms has driven a population-level collapse in mental health (Vuorre and Przybylski, 2023). Second, effects are not uniform: a ‘differential susceptibility’ model proposes that social media harms a vulnerable minority while leaving most users largely unaffected, and may even benefit some (Valkenburg, Meier and Beyens, 2022). These objections are well taken, but they refine the argument rather than refuting it. An average effect that looks small can still represent serious harm concentrated within a vulnerable subgroup — which is precisely the population that public health exists to protect. And conceding the benefits is entirely compatible with the central claim, because the goal is not to abolish social media but to change the conditions under which young people use it.
If social media is a modifiable risk factor, the appropriate response is proportionate harm reduction rather than prohibition, mirroring the way society already manages other everyday risks. At the level of design, platforms could default younger users into protective settings: chronological rather than algorithmically optimised feeds, limits on infinite scroll and autoplay, and the removal of visible ‘like’ counts for minors. Regulation can make such features mandatory rather than voluntary; age-appropriate design codes that require services to act in the best interests of child users demonstrate that this is achievable without banning the technology outright. In education, embedding digital literacy into the curriculum can help adolescents recognise idealised self-presentation, understand how feeds are engineered to capture attention, and build healthier habits around sleep and comparison. At the individual level, simple strategies — curating feeds towards active rather than passive use, disabling non-essential notifications and protecting a screen-free wind-down before sleep — have a plausible protective effect. Clinicians and schools, for their part, can treat patterns of use as one routine question among many when a young person presents with low mood, in the same way that sleep, diet and exercise are already discussed, so that support reaches those most affected rather than being imposed indiscriminately on everyone. The common thread is that harm is contingent on how the technology is designed and used, which means that it can be reduced without discarding the real value these platforms provide.
The question is not whether social media is wholly good or wholly bad, because it is plainly neither. The evidence supports a more disciplined conclusion: for a generation of adolescents who spend several hours a day inside environments engineered to capture their attention, heavy and passive use is associated with poorer mental health, those associations are at least partly causal, and the mechanisms — comparison, displacement, addictive design and online cruelty — are properties of the platforms rather than failings of their users. The effects are small for the average teenager, meaningful across a whole population, and severe for a vulnerable minority. Recognising social media as a modifiable risk factor reframes the debate productively, directing attention away from unwinnable arguments about whether the technology should exist and towards the practical questions of design, regulation and education that decide whether its undoubted benefits can be enjoyed without its avoidable harms. That, encouragingly, is a problem society already knows how to solve.
