🗣️ How to use "Dummheit"?

Die Dummheit is used to describe a lack of intelligence or unwise behavior. It is a strongly judgmental word.

• Context: Mostly in informal to normal conversations, but also in literature or philosophy to characterize human behavior. In formal or scientific contexts, more neutral terms like "kognitive Einschränkung" (cognitive impairment) are often preferred.
• Distinction from "Unwissenheit" (Ignorance): Dummheit is not the same as Unwissenheit. Ignorance means not knowing something (which can often be remedied), while Dummheit describes more the inability to apply knowledge or think logically. One can be very intelligent but ignorant in a certain area.
• Typical Phrases: "aus Dummheit" (out of stupidity), "eine Dummheit begehen/machen" (to commit/do a stupid act), "jemandes Dummheit" (someone's stupidity).

⚠️ Caution: Directly accusing someone of Dummheit is very offensive.

📜 Poem about Stupidity

Die Dummheit schleicht auf leisen Sohlen,
lässt manchen Plan sich nicht erholen.
Sie flüstert ein, man sollt' es wagen,
doch Klugheit würde leise fragen.
Sie trägt das Kleid der Sicherheit,
doch führt oft nur zu Herzeleid.
Drum prüfe wohl, was du beginnst,
damit du nicht der Dummheit Zins gewinnst.

Translation:
Stupidity creeps on silent soles,
Lets many a plan not recover.
It whispers one should dare to try,
But cleverness would softly ask why.
It wears the dress of certainty,
But often leads to misery.
So check well what you start anew,
Lest stupidity's interest you accrue.

❓ Riddle

Ich habe keinen Kopf, doch mache Gedanken leer.
Ich habe keine Hände, doch schaffe Unglück schwer.
Man lernt aus mir, sagt man, doch weh tut's meistens sehr.
Ich bin das Gegenteil von Klugheit, wer bin ich, bitte sehr?

Translation:
I have no head, yet I make thoughts empty.
I have no hands, yet I create heavy misfortune.
One learns from me, they say, but it usually hurts a lot.
I am the opposite of cleverness, who am I, if you please?
