In the page of 'perception' from Cambridge Dictionary, there's such a sentence as follows.
He's not known for his perception.
The perception here means (according to Cambridge Dictionary)
someone's ability to notice and understand things that are not obvious to other people.
The meaning of the sentence is kind of vague to me. I can come up with 2 different understandings of this same sentence:
- He has little perception.
- He has good perception, but somehow, his good perception is unknown to others.
Which is correct? What does the sentence mean?
