Claim analyzed
“The prevalence of mental health issues among young adults in Western countries has significantly increased due to social media use.”
The Conclusion
Executive Summary
The claim is not supported by evidence. While some studies show correlations between heavy social media use and mental health issues, the strongest longitudinal research finds typical social media use does not predict later mental health problems. The evidence shows rising "problematic use" rates, not proof that social media causes population-wide mental health increases.
Warnings
- The claim conflates correlation with causation - associations between social media and mental health don't prove social media causes mental health problems
- Longitudinal studies specifically testing predictive relationships find little evidence that typical social media use leads to later mental health issues
- The evidence focuses on heavy/problematic use subgroups but makes broad claims about all young adults in Western countries

The Debate
The for and against arguments
The World Health Organization (Source 1) documents a dramatic 57% increase in problematic social media use among adolescents from 2018 to 2022, while multiple systematic reviews including Source 2 and Source 5 consistently demonstrate that higher social media usage correlates with increased depression, anxiety, and psychological distress among young adults. Source 6 provides compelling evidence from over 40,000 EU adolescents showing that excessive social media use (over 3 hours daily) is directly associated with depression and anxiety, with nearly half of 15-year-olds reporting depression and over half struggling with anxiety.
You're substituting “problematic use rose” and “heavy use correlates with distress” for the motion's much stronger causal claim that overall prevalence has “significantly increased due to social media”: WHO's figure is about problematic use rates, not a demonstrated driver of population-level prevalence increases, and the reviews you cite (Source 2; Source 5) are framed as associations that don't establish directionality or rule out confounding. And your reliance on the EU 40,000-sample result (Source 6) cherry-picks an “excessive use” subgroup while ignoring higher-quality longitudinal findings that typical use does not predict later depression/anxiety/self-harm (Source 8, University of Edinburgh) and UK evidence finding little link between more time and more problems (Source 14, The Health Foundation), which directly undercuts your “due to” inference.
The motion asserts a significant increase in young-adult mental health problems “due to” social media, but higher-quality longitudinal evidence finds little to no predictive link from typical (low-to-average) social media use to later depression, anxiety, self-harm, or suicide attempts (Source 8, The University of Edinburgh), and UK SPHR/JMIR research likewise reports little evidence that more time on social media is associated with more mental health problems (Source 14, The Health Foundation). Even perception data undercuts the claim of a broad causal driver: most teens report social media has a neutral impact on their mental health and only a minority identify it as the main factor, which is inconsistent with social media being the primary cause of a significant prevalence increase (Source 4, Pew Research Center).
Your reliance on Source 8 and Source 14 cherry-picks studies examining only "low to average" usage while ignoring the WHO's documented 57% surge in problematic social media use (Source 1) and the compelling evidence from Source 6 showing that excessive usage—over 3 hours daily—directly correlates with depression and anxiety in nearly half of adolescents. You misrepresent Source 4's findings by conflating teens' self-reported perceptions with objective causal evidence, when systematic reviews like Source 2 and Source 5 provide rigorous meta-analyses demonstrating consistent links between high social media engagement and psychological distress across multiple populations.

The Adjudication
How each panelist evaluated the evidence and arguments
The most authoritative and independent source here is WHO (Source 1), but it reports rising “problematic social media use” and concern about impacts—not evidence that Western young-adult mental-health prevalence has increased *due to* social media; the stronger causal/predictive evidence in this pool is the longitudinal UK work summarized by University of Edinburgh (Sources 8/10/13) and the SPHR/JMIR summary via The Health Foundation (Source 14), both finding little evidence that time spent predicts later mental ill-health (at least for low-to-average use). Much of the supporting material (Sources 2, 5, 6, 7, 9, 11, 12) is largely correlational, secondary, or non-peer-reviewed summaries and does not independently establish population-level prevalence increases attributable to social media, so overall trustworthy evidence does not substantiate the claim's strong causal attribution.
The claim asserts a causal relationship ("due to") between social media use and a significant increase in mental health prevalence, but the evidence chain commits multiple logical fallacies: Sources 1-2, 5-7, 9 demonstrate correlations and associations (not causation), Source 1 measures problematic use rates (not overall prevalence increases), and the proponent cherry-picks "excessive use" subgroups (Source 6) while dismissing longitudinal evidence (Sources 8, 10, 13, 14) showing low-to-average use does not predict later mental health problems—a classic post-hoc ergo propter hoc fallacy conflating correlation with causation, compounded by hasty generalization from high-use subgroups to the entire young adult population. The opponent's rebuttal correctly identifies that the evidence does not logically support the specific causal claim made, as the strongest longitudinal studies (Sources 8, 14) refute predictive links for typical usage patterns, and even supportive sources acknowledge associations without establishing directionality or ruling out confounding variables; therefore, the claim is false because the inferential leap from "some correlation exists in heavy users" to "prevalence has significantly increased due to social media" is not logically warranted by the evidence.
The claim overstates causality and population-level impact by treating correlational findings about heavy/problematic use (Sources 2,5,6) and a rise in “problematic use” prevalence (Source 1) as proof that overall young-adult mental-health prevalence in Western countries has “significantly increased due to” social media, while omitting that longitudinal evidence finds low-to-average use does not strongly predict later mental ill health and that “more time” shows little evidence of association in some UK research (Sources 8,14), plus perception data suggests many teens report neutral effects (Source 4). With full context, the evidence supports that heavy/problematic social media use can be associated with worse outcomes for some groups, but it does not substantiate the broad causal attribution that rising prevalence is significantly “due to” social media across Western young adults, so the overall impression is misleading.
Adjudication Summary
All three panelists identified significant problems with this claim, though they reached different verdict categories. The Source Auditor (4/10, Misleading) found that while WHO is authoritative, it documents "problematic use" rates rather than proving causation, and the strongest longitudinal evidence actually contradicts the causal claim. The Logic Examiner (3/10, False) identified multiple logical fallacies, particularly post-hoc reasoning that conflates correlation with causation and cherry-picking that emphasizes heavy-use subgroups while dismissing longitudinal studies showing typical use doesn't predict mental health problems. The Context Analyst (5/10, Misleading) noted the claim overstates causality by treating correlational findings as proof of population-level causal effects while omitting contradictory longitudinal evidence. The consensus points to a fundamental flaw: the claim asserts causation ("due to") but the evidence primarily shows correlations, and the strongest longitudinal studies (Sources 8, 14) actually refute predictive links for typical social media use. The claim conflates rising "problematic use" rates with overall prevalence increases and extrapolates from heavy-use subgroups to make broad population claims unsupported by the evidence.
