The skills may be different, but the assumption that everyone should have at least moderate skill at what comes easy to you is the same.

And the belief that "Y, rather than Z is the obvious inference given X " is different across people, and is evidence of psychological diversity, and is the case frequently, including here. The universal presence of a belief of the form "You should have moderate skill at X" does not contradict this.

If Oceanians consider Eur...Eastasians, their mortal enemies, unworthy of human dignity, and Eastasians regard Oceanians, their hated antagonists, as little more than maggots to be crushed, then that is not an example of psychological diversity; instead, it's two different instances of underlying psychological unity - in this case, of the universal "Us vs. Them" heuristic.

But this doesn't map to an "us vs. them" heuristic; it maps to an "X implies Y vs. X implies ~Y". The fact that the differing beliefs about what X implies leads to a universal dislike of the "other" does not deny the neurodiversity in the former heuristic.

Yes but the term "psychological unity" is about hardware. Neurodiversity in terms of magazine selection does not necessarily have a genetic link even though it will show that we are neurodiverse. Difference in magazine selection can lead to a difference in what one believes X implies.
