No offense but why are mostly autistic people so stupid?

Look I’m not trying to be mean but they’re so stupid I’m so many things. I have a cousin who is autistic and what I don’t understand is that she is so smart academically, but when it comes to everyday problems, people are relationships, she’s so……naive and stupid. Like she hung out with a group of girls and she didn’t see that those girls had a bad reputation. They used her, they treated her like shit when they’re not around others, and they only phone her when they need something. My cousin kept saying they’re probably are busy but she didn't realize she was being used. They used her for her money. She is so horrible at social cues. Also she sees a lot of good in people even though some are horrible and that girl will be friends with anyone. I know her parents told her not everyone is her friend and doesn’t have her best interest. She STILL has problems with it. She should have know and people still have to remind her! She said she doesn’t need a reminder but she obviously does because she’s too STUPID to see it! How can someone so smart but stupid? My cousin is 30 and she should know better!
