They don't.

1. LLMs are put in a position where everything they say is clearly based on encyclopedic knowledge of absolutely everything

2. LLMs try to use language that is very general, helpful and friendly, and as a result end up not properly portraying nuances, like "sometimes", "in this case", "not always", etc.

3. Humans are capable of saying "I don't know", or "I think XYZ but I'm not sure"

4. Humans convey that they aren't sure by lack of nonverbal confidence

These are differing sets of skills and issues. LLMs dont behave like humans, they don't solve things like humans, and people take what they say at face value by default.
