What does the phrase "the blind leading the blind" imply?

The phrase "the blind leading the blind" implies that individuals who lack knowledge or insight (the blind) cannot effectively guide others who are similarly uninformed. This expression draws on the metaphorical representation of blindness, where those who cannot see (figuratively speaking) are in no position to lead others along a path toward understanding or enlightenment. It underscores the futility of a situation where both the leader and the followers are equally misguided, suggesting a lack of wisdom or knowledge essential for proper guidance.

The other choices, though they may have relevance in specific contexts, do not encapsulate the primary implication of the phrase as directly as this option does. While the idea of moral blindness or general ignorance could be part of a broader interpretation, they do not specifically capture the essence of ineffective leadership due to a lack of wisdom, which is the core meaning of the expression.
