"More harebrained" is an idiomatic expression used to describe an idea, plan, or decision that is even more foolish, reckless, or impractical than one that is already considered harebrained. It is a comparative phrase formed by combining the word "more" and the adjective "harebrained," which means lacking good sense, thoughtless, or nonsensical.
The term "harebrained" derives from the archaic belief that hares, due to their erratic and unpredictable behavior, possessed a nervous system connected to their brains. Consequently, they were regarded as creatures with a lack of logic or rationality. When expanded with "more," the phrase emphasizes the already existing foolishness or absurdity to an even greater extent.
When something is described as "more harebrained," it suggests that it surpasses the level of impracticality or irrationality of a typical harebrained idea. It implies that the course of action being discussed is exceptionally ill-conceived, lacking any reasonable basis, and likely to result in negative or undesirable consequences.
This idiom is commonly used in informal conversations or writing to express disbelief, exasperation, or criticism towards an absurd notion or plan. Its figurative connotation effectively communicates the notion that the proposed idea is so foolish that it resembles the nonsensical behavior associated with hares, emphasizing the point that it is neither logical nor wise.
