愚蠢

• Pinyin: yú chǔn
• Hanzi breakdown: 愚 = 禺 + 心 (monkey + heart — foolish thinking); 蠢 = 春 + 虫虫 (spring + two insects — insects moving blindly, hence stupidity)

Meaning

Stupid; foolish; idiotic. Describes a serious lack of intelligence, judgment, or wisdom — in decisions, actions, or thinking.

A strong negative judgment, stronger than 笨 (dull/slow) and less forgiving than 幼稚 (immature). Can describe a person's inherent intellectual capacity, a specific decision, or a policy. In formal writing often refers to strategically misguided decisions rather than intellectual capacity. Saying someone is 愚蠢 is a serious insult, but calling a decision or policy 愚蠢 is common in critical analysis.

Examples

1. 历史上许多战略灾难都源于领导者愚蠢的傲慢和对情报的忽视。 Many strategic disasters in history came from leaders' foolish arrogance and their neglect of intelligence reports.
2. 这项定价政策推出三个月就被迫撤回，被认为是愚蠢决策。 This pricing policy was forced to be withdrawn after three months and was regarded as a foolish decision.
3. 苏格拉底说，真正愚蠢的人不是无知，而是自以为有知识却不知道自己无知。 Socrates said that the truly foolish people are not those who are ignorant, but those who think they have knowledge while not realizing their own ignorance.
