Critical Reading of Tech News: A Structured Question Set for Evaluating Scientific Claims
科技新闻批判性阅读：评估科学主张的结构化问题清单
-
Before accepting a headline like ‘Breakthrough AI Cures Cancer’, ask: Was the study peer-reviewed, and if so, in which journal—with what impact factor and editorial independence record?在相信‘突破性AI治愈癌症’这类标题前，请先问：该研究是否经过同行评审？若已评审，发表于哪本期刊？影响因子和编辑独立性记录如何？
-
Identify the evidence hierarchy: Does the claim rest on preclinical cell cultures, animal models, or randomized controlled trials in humans—and were control groups properly blinded?明确证据等级：该主张基于体外细胞实验、动物模型，还是人类随机对照试验？对照组是否采用盲法？
-
Check for conflict-of-interest disclosures: Startups funding their own press releases rarely mention that lead authors hold equity stakes worth millions in the cited technology.核查利益冲突披露：初创公司资助自身新闻稿时，往往不会提及主要作者持有相关技术数百万美元的股权。
-
Quantify ambiguity: Phrases like ‘significant improvement’ lack meaning without effect sizes, confidence intervals, and baseline comparators—essential for judging clinical relevance.量化模糊表述：‘显著改善’等措辞若缺少效应量、置信区间及基线对照数据，便无实际意义，而这些正是判断临床价值的关键。
-
Trace methodological limitations: A neural network trained only on Caucasian skin lesions will likely fail on Fitzpatrick Type V–VI dermatology images, yet such caveats vanish in syndicated coverage.追溯方法学局限：仅用白种人皮肤病变图像训练的神经网络，在Fitzpatrick V–VI型皮肤影像上很可能失效，但此类限制常在转载报道中被忽略。
-
Assess scalability: Lab-scale quantum encryption may achieve 100 kbps over 10 km fiber, but real-world deployment requires repeaters vulnerable to side-channel attacks—a detail omitted in investor briefings.评估可扩展性：实验室级量子加密或可在10公里光纤上实现100 kbps速率，但实际部署需中继器，而后者易受旁路攻击——这一细节常被投资者简报刻意省略。
-
Interrogate framing: Describing fusion energy as ‘unlimited clean power’ ignores tritium breeding constraints, neutron embrittlement of reactor walls, and lithium supply chain bottlenecks.质疑表述框架：将核聚变能源描述为‘无限清洁能源’，回避了氚增殖限制、中子辐照导致反应堆壁脆化、锂供应链瓶颈等现实约束。
-
Compare with consensus: Does the claim align with IPCC synthesis reports or NASEM consensus studies—or does it represent a single outlier paper contradicted by five subsequent replications?对照科学共识：该主张是否与IPCC综合报告或美国国家科学院（NASEM）共识研究一致？抑或仅为一篇被后续五项重复研究证伪的孤立论文？
-
Examine source proximity: Was the ‘expert quote’ from a researcher directly involved, or a commentator interpreting second-hand conference abstracts without access to raw data?审视信息来源距离：所谓‘专家引述’，是来自直接参与研究的学者，还是仅凭二手会议摘要进行解读、且未接触原始数据的评论员？
-
Finally, consider omission bias: Coverage of battery breakthroughs rarely mentions cobalt mining ethics or graphite anode processing emissions—critical context for sustainability claims.最后，警惕遗漏偏差：电池技术突破的报道极少提及钴矿开采伦理问题或石墨负极加工过程中的碳排放——这些对可持续性主张至关重要。
