A "Simpleton" refers to a person who is perceived as lacking intelligence or common sense. This term is often used in a light-hearted or humorous context to describe someone who may be naive or overly trusting. Simpletons may struggle to understand complex ideas or situations, leading to misunderstandings. In literature and folklore, simpletons are frequently depicted as characters who, despite their lack of intelligence, often possess a kind heart or good intentions. They can sometimes outsmart others through their innocence or straightforwardness, as seen in tales like The Boy Who Cried Wolf or Jack and the Beanstalk.
