SLIs' Fe-polr is worse than ILIs' because of the lack of intuition. SLIs definitely come off as more hedonistic, ILIs' pragmatism makes them seem responsible.
This forum has a weird understanding of IXTx types, imo. ILIs are typed as LIIs, and LSIs as SLIs. I don't think that ILIs fit the stereotype of the unhygienic, nerdy NT. My brother is an ILI, and what strikes me immediately about him are *good* Gamma values. He takes care of his appearance. He appreciates when people talk things out, thereby avoiding unsaid emotional turmoil. He appreciates clever verbal interaction within a group, whereas LIIs appreciate their own internal wordplay. He favors being "exclusive" but through appropriate and polite conversation, where the person being made fun of may not even realize they are the butt of the joke (whereas Beta straight up bullies someone then smooths it over with Fe). He pursues a conversation to its proper end, whereas LIIs frequently leave people hanging.
I also don't think that SLIs fit the strong, silent and reliable stereotype. Possibly among older SLIs, like baby boomers, you can appreciate them for their skills and craftsmanship, or whatever, probably their generation was more Delta and they had more time and opportunity to develop. Among my own (in 20s) peers, the most obvious thing about SLIs is the IP temperament, hedonism, and lack of purpose. One of my best friends from college is SLI. He is an avid reader and collector of information, but somehow went off the deep end after college. He gained a lot of weight, developed OCD (though I've never seen him display OCD behaviors, he says it's the mental kind?), and has not tried to embark on any type of career whatsoever. He would rather leave things unsaid and let inner turmoil accumulate. He is very much affected by on-the-surface aesthetics, like he judges the quality of a thing by whether or not it looks *cool* according to what's going on at the moment. He does have a knack for knowing exactly which song, movie or TV show everybody will be talking about next week.
