huh?
I'd say I think this was copied from an SLI description except that I don't even think this matches up with the descriptions that I've read, let alone what I've observed in the real world. my SLI brother is very much clever and insightful and I don't think this is uncommon among SLIs, like at all, and by that I mean I'm pretty sure this is something they're known to be skilled at. if it isn't a topic they're interested in then they may not care enough to share their input but I think that probably rings true for most people. I don't think they're "bad" at forecasting so much as they just don't care about it. they're generally cool, calm, and collected. for that reason, they're great in "extreme situations". If we're taking socionics into account while making these character assessments, then why would Ni PoLR (assuming Ni = forecasting) care about information pertaining to Ni?
to OP: any social interaction where you feel the need to filter your speech/alter your behavior to appease someone else is not a good interaction. anyone who would require you to go to such lengths to appease them probably isn't someone you wanna hang out with anyway. SLIs are like the prototype for the friend who likes to kick back and shoot the shit, or so I thought, maybe I'm wrong. just be yourself and pay attention to his/her reactions, adjust to them accordingly, as anyone would, but don't feel the need to tiptoe around him/her. that's not fun for anyone.
