LSI's run on pure system logic. Everything has to fit together before they will accept it as true. And they are looking for socially generous people who are easy extroverts.
If you meet an LSI, the easiest way to get along with them is to tell them the truth in all things. Be completely up front about who you are and what you do. If you are a crack-smoking drug addict with low-grade narcolepsy and a penchant for buggery, say so. They won't believe you, of course, and they will constantly question you and fact-check your story, but if you absolutely never lie to them, you will gain their respect and some trust. They have an amazing ability to not pass judgement on you, but they really, really do pass judgment on the reliability of your information.
The "logically fitting together" part is what they do when you tell them something. They consider it and see if it fits into a likely scenario. If it does not, or if your story has any inconsistencies, then you might find your freedoms around them restricted.*
LSI's basically filter facts, and only allow the ones that fit into their internal structures to add to those structures. If you tell them that the sky is green, that just doesn't get in, and you're not so much stupid as you are a source of unreliable data, and therefore are of little use to them.
*I know a male EIE who married a female LSI technical writer. The EIE has been living off his parents all his life and is fantastic at emotional manipulation. I mean, I like the guy, but he's not using his powers for good.
After he was married for a while, I guess he felt like his wife wasn't enough or something and he cheated on her with this HS ex-GF who was just a routine deed, and then after lying about it, he told his wife what happened. He probably thought he'd get some drama, some excitement, and then he'd lay on the emotional stuff and everything would be good again and he'd have some affirmation that he was wanted. That's not how it played out.
She kicked him out.
He begged to come back.
She told him to get fucked, she was totally done with him.
He complained about the situation to everyone he and she knows. It doesn't matter. She's done, and he's fucked.
Let me just say that he's probably never going to find someone like her, ever again.
