Food for thought, but my LSI friend (dunno which subtype) scores /high/ on openness to experience (I even gave him a real Big-5 questionnaire once, so I know his scores). Higher openness is mostly correlated with higher intelligence, and he is intellectually curious (and an academic).
The one SLI I like seems to very open as well (Si-sub), you do remind me of him (albeit he is more delicate/considerate - not to offend you ofc!, aligns himself to stoicism, also he has close NF friends as well).
also I score high on openness typically
