People from one human-populated would rarely count as neurotypical on any other human-populated planet. To say this requires some measure on the human-populated planets across the multiverse; but if you pick a sensible such measure, the truth of the statement should be obvious enough on priors. Begin, say, from 50,000 years ago in dath ilan's history; most descendants of that primate species can interbreed with each other, if they're still extant and haven't deliberately shaped themselves otherwise. Thellim's world of "Earth" branched off no earlier than that - quite a bit later, in fact.
Keltham looks human. He can interbreed with humans. He is in fact human. But Keltham, on a deep level, and in several ways, does not work quite like a Golarionite expects humans - or their related mortal species - to work.
Dath ilan, from the perspective of most human-populated worlds, has some unusual problems. Dath ilan has noticed those problems at all, but they don't know those problems are unusual or unusually severe. They have nothing else to compare themselves to. The dath ilani don't know that their failures are not part of the plan, any more than they think of themselves as being unusually good at coordination or decision theory, or their planet having above-average intelligence.
Every human-populated world that is alone in its neighborhood of the multiverse "dances like nobody is watching", you could say. If a planet is embarrassing itself in some regard, compared to the average descendant of that 50,000-year ancestral branching point, most such planets have absolutely no idea. If you ask the inhabitants to guess where they fall on the unseen spectrum of world-branches, they will have no more-sensible guess than 'Probably we're somewhere in the middle?'
