Generation Z，也就是第一个完全在网路上成长起来的世代，正被一种社群媒体环境所塑造，在这里，事实、感受与身分被融合到同一个资讯流中。文章以 TikTok 上一段爆红的北极熊影片，与 IPCC 气候报告克制的语言形成对比开场，说明 Z 世代如何同时透过情绪与证据来接触真相。文章主张，自 2010 年以来，多个国家的青少年心理健康指标都在恶化；来自美国、英国、加拿大、澳洲和欧洲的调查资料显示，到 2012 至 2014 年已出现相似的趋势线，这与智慧型手机、前置相机以及演算法平台成为青少年社交生活核心的时间点相吻合。
研究人员使用 CDC Youth Risk Behavior Survey 的资料、密西根大学的 Monitoring the Future 研究，以及国际资料集，发现忧郁症状、睡眠中断、悲伤、绝望、孤独、自我伤害与社交退缩都大幅上升，尤其是青少女；同时，面对面互动减少，上网时间增加。文章指出，更深层的转变是文化与认知上的：社群媒体把真相从制度化的证据与辩论系统，移到个人化、由演算法强化的资讯流中。它提到 Emma Lembke 的警告：以获利为导向的注意力经济把互动度置于福祉之上；也提到 Scott Galloway 的论点，认为像 Facebook 和 TikTok 这样的平台已成为影响力引擎；同时，AI 生成的假现实威胁正加速扩大，包括 deepfakes、克隆声音、假新闻，以及拥有数百万追随者、完全由 AI 生成的人格。
2023 年一项关于 Z 世代资讯习惯的 Google 研究描述了「information sensibility」，这是一种受社会脉络影响的可信度判断方式：年轻人被动接触资讯、以情绪回应、与同侪讨论，必要时才在之后查证。文章把这视为一种分散式验证系统，属于集体而非机构性的运作，因此让较早期的媒体素养建议变得不那么有效。文章最后指出，Z 世代并不是抛弃真相，而是在重新定义真相：爆红程度越来越取代可信度，情绪指示哪些事值得注意，而团结则成为一种验证形式。其影响不只涉及心理健康，也延伸到公共生活；在那里，行动主义、新闻、娱乐、广告与宣传都在同一个资讯流中竞争，而像 Fridays for Future 这样的气候运动则显示，情感共鸣、同侪分享与行动如何把被感知的真相转化为集体力量。
Generation Z, the first cohort to grow up fully online, is being shaped by a social media environment where facts, feelings, and identity are fused into the same stream. The article opens with a contrast between a viral polar bear video on TikTok and the restrained language of an IPCC climate report to show how Gen Z encounters truth through emotion as much as evidence. It argues that, since 2010, adolescent mental health indicators have worsened across multiple countries, with survey data from the United States, the United Kingdom, Canada, Australia, and Europe showing similar trend lines by 2012 to 2014, coinciding with smartphones, front-facing cameras, and algorithmic platforms becoming central to teen social life.
Researchers using CDC Youth Risk Behavior Survey data, the University of Michigan’s Monitoring the Future study, and international datasets found steep rises in depressive symptoms, sleep disruption, sadness, hopelessness, loneliness, self-harm, and social withdrawal, especially among teenage girls, alongside less face-to-face interaction and more time online. The article says the deeper shift is cultural and cognitive: social media moved truth from institutional systems of evidence and debate into personalized, algorithmically reinforced feeds. It highlights Emma Lembke’s warning that a profit-driven attention economy prioritizes engagement over well-being, Scott Galloway’s argument that platforms like Facebook and TikTok have become influence engines, and the accelerating threat from AI-generated fake realities, including deepfakes, cloned voices, bogus news, and fully AI-generated personas with millions of followers.
A 2023 Google study on Gen Z information habits described “information sensibility,” a socially informed way of judging credibility in which young people encounter information passively, react emotionally, discuss it with peers, and verify later if needed. The article frames this as a distributed verification system that is collective rather than institutional, making older media-literacy advice less effective. It concludes that Gen Z is not abandoning truth but redefining it: virality increasingly substitutes for credibility, emotion signals what deserves attention, and solidarity becomes a form of verification. The implications extend beyond mental health to public life, where activism, news, entertainment, advertising, and propaganda all compete in the same feed, and where climate movements like Fridays for Future show how emotional resonance, peer sharing, and action can turn perceived truth into collective force.
