你的大脑从未被设计来承载如此多的坏消息。
Your brain was never designed for this much bad news

如今,许多人正经历“新闻疲劳”。近 70% 的加拿大人因感到不知所措和无力而选择偶尔回避新闻。作为一名发展心理学家,我认为这并非性格缺陷,而是人类大脑因进化而产生的“负面偏见”所带来的必然反应。 我们的祖先通过优先关注即时的地方性威胁得以生存。然而,当今我们古老的神经系统却不断受到全球性危机的轰炸,从而引发持续的生理压力反应。这种错位可能导致“问题性新闻消费”,进而严重影响心理健康,尤其是对于边缘群体而言。 虽然回避并非解决之道(健康的民主社会需要知情的公民),但我们必须改变获取信息的方式。为了应对这种认知负荷,我们应该: * **限制消费:** 设置特定的时间段来阅读新闻。 * **优先考虑质量:** 选择深度报道,而非杂乱的社交媒体资讯流。 * **寻求行动力:** 将认知转化为行动,以减轻痛苦。 * **过滤“愤怒诱饵”:** 识别那些旨在激发情绪反应的内容。 尽管世界新闻依然沉重,但只要我们更有意识地参与其中,就能保护好自己的心理健康。

近期的一场 Hacker News 讨论探讨了长期接触全球负面新闻带来的心理负担,并引用了尼尔·波兹曼(Neil Postman)提出的“躲猫猫世界”(Peekaboo World)概念。该理论指出,现代媒体不断向我们轰炸那些我们无力干预的重大全球性问题,导致人们陷入一种持续且无助的焦虑状态。 评论者们提出了几种应对这种“信息过载”的策略: * **本土化:** 专注于当地新闻。用户发现这比关注全球新闻压力要小得多,且与日常生活关联更紧密。 * **相关性过滤:** 有用户提议采用“爆炸半径”法来获取媒体资讯,即根据地理距离和个人影响程度对新闻进行排序。通过优先关注身边的事件并过滤掉远方无法控制的危机,用户可以找回自己的心理带宽。 总之,大众普遍认为,限制对遥远全球事件的关注——因为这些往往超出个人的影响范围——是减轻压力并改善心理健康的一种切实可行的方法。

During several recent conversations, people have told me that they’ve stopped checking their phones in the morning. Not because nothing was happening, but because everything was. They described the feeling as standing under a waterfall of perpetual bad news.

This experience is far from an isolated one. According to Reuters Institute’s 2025 Digital News Report, 69 percent of Canadians at least occasionally avoid the news now.

Globally, 40 percent report they at least sometimes or often do the same, the highest figure ever recorded. People shared consistent reasons for this: the news put them in a bad mood, they felt overwhelmed and powerless to act.

As a researcher in developmental psychology, focusing on social development and psychological well-being, I argue that news fatigue is not laziness, weakness or a generational decline in civic interest. It’s the predictable response of a human brain meeting an environment it was never designed to navigate.

Wired for bad news

Long before smartphones or even the printing press, our cognitive architecture was shaped by a single problem: stay alive long enough to reproduce. Our ancestors whose attention drifted past the rustle in the grass left fewer descendants than those who froze, looked and listened.

The brain that paid attention to threats was the brain that survived.

This is the foundation of what psychologists call the negativity bias, one of the most replicated findings in cognitive science. Across decades of research, the human mind has been shown to weigh negative information more heavily than positive, attend to it faster and remember it longer.

A predator nearby mattered more than a beautiful sunset. The cost of missing a real threat was death, while the cost of overreacting was a few minutes of wasted vigilance. The asymmetry made this bias adaptive.

Here is the problem: the human brain has not changed since then. We are the same species as we were thousands of years ago. What’s changed is the size of the world it’s asked to scan for threats.

Scanning the whole world

For most of human history, the threats our nervous system processed were local. A neighbouring tribe. A drought. The illness of a child we personally knew. Information about distant places would barely arrive, and if it did, it was mainly irrelevant.

In 2026, the same neurological system is being asked to absorb a war in one region, a financial shock in another, a climate disaster in a third and a violent crime in a fourth, all before lunchtime.

A study published in the scientific journal Nature Human Behaviour examined more than 105,000 real news headlines viewed nearly six million times. Each additional negative word increased click-through rates, while positive words had the opposite effect.

Recent studies suggest people around the world demonstrate measurably stronger physiological responses to negative news than to positive news. The body is reacting before the mind has decided whether the threat is relevant.

Some researchers have introduced a clinical framework for what happens in this instance called Problematic News Consumption (PNC) — a pattern of news engagement that results in preoccupation, dysregulation and disruption to daily functioning. In their 2022 study, the researchers found that 17 percent of American adults qualified as having severe levels of PNC. Among that group, 61 percent reported feeling unwell quite a bit or very much, compared with six percent of those who didn’t.

For minority populations, news fatigue may be even more consequential.

Repeatedly witnessing harm directed at our own groups, even when we’re not the immediate target, can have a significant psychological impact on people from the same group affiliation. For racialized communities, such as immigrants, the cognitive load could be even heavier, and the option to simply stop watching is much harder to exercise when the news is about their country of origin.

Looking away is not the fix

What’s the solution to news fatigue? Well, it’s not avoidance. A democracy depends on informed citizens.

Many adults already cite the spread of misleading information as a major source of stress. Withdrawing from accurate, trustworthy information only deepens the problem. We’re wired to pay more attention to bad news, and that kind of content will find its way to us one way or another.

The fix is to manage the consumption and the sources.

Several approaches can help manage news fatigue and protect mental health. Containing news consumption to defined windows of time reduces the sense of being overwhelmed. Choosing depth over volume also matters: one carefully reported long-form article will inform you better than bursts of random, unreliable and emotionally loaded posts on Instagram.

There is also value in distinguishing between information and action — research on perceived control and stress consistently shows that the gap between awareness and agency is one of the strongest predictors of psychological distress. Identifying what you can actually do about what you read in the news, however small, regulates that response.

Finally, be wary of “rage bait” — intentionally provocative messages or content designed to boost engagement on social media platforms by eliciting negative reactions. Recognizing that certain content creators want to provoke rather than reflect reality creates useful cognitive distance.

The news will not become less “heavy.” But our relationship with it can become more deliberate. Our brains were not built for this scale of input. They were, however, built to learn to adapt.The Conversation
