Foolishness

Foolishness is the inability or failure to act following reason due to lack of judgment, stupidity, stubbornness, etc.^[1] The things such as impulsivity and/or influences may affect a person's ability to make reasonable decisions.^{[citation needed]} Other reasons of apparent foolishness include naivety, gullibility, and credulity. Foolishness differs from stupidity, which is the lack of intelligence.^[2] An act of foolishness is called folly. A person who is foolish is called a fool. The opposite of foolishness is prudence. ^[3]
