一概而论

• Pinyin: yī gài ér lùn
• Hanzi breakdown: 一 = uniform (single horizontal stroke); 概 = 木 + 既 (grain-levelling stick — standardise); 而 = pictographic beard/whiskers — a conjunction linking clauses; 论 = 言 + 仑 (speech + order — to reason/discuss systematically)

Meaning

To lump everything together; to make a sweeping generalisation; to treat all cases the same without regard for differences.

A four-character idiom (成语) almost always used in the negative: 不能一概而论 (cannot make sweeping generalisations) or 不宜一概而论. It signals the need to consider nuance, context, or individual variation, and is common in academic argument, critical analysis, and rational discourse.

Examples

1. 犯罪行为的成因极为复杂，涉及家庭、教育、社会环境等多重因素，不能简单地一概而论，将其归结为某一单一原因。 The causes of crime are extremely complex, involving family, education, the social environment, and many other factors. You can’t make a sweeping generalization and pin it on a single cause.
2. 这二十位受访者来自不同的文化背景和社会阶层，研究者在分析数据时特别强调，其结论不能一概而论地推及整体人群。 These twenty interviewees came from different cultural backgrounds and social classes. When analyzing the data, the researchers emphasized that their conclusions can’t be generalized to the population as a whole.
3. 青少年沉迷网络游戏的问题需要具体分析，有的是逃避学业压力，有的是社交需求，不能一概而论地给所有玩家贴上负面标签。 Teenagers’ addiction to online games needs to be analyzed case by case: some are escaping academic pressure, others are seeking social connection. You can’t paint all players with the same negative label.

Do Say

Don't Say

• 他一概而论地解释了 — 一概而论 is typically used in the negative or as a warning against oversimplification; using it neutrally or positively (他一概而论地解释了一切) implies faulty reasoning, which is rarely what a speaker intends positively; restructure to 他给出了一个笼统的解释 if a neutral description is needed
