A quantum theory of magnetism

Is it possible that, as a previously undemonstrated corollary of the Pauli exclusion principle, the same sort of "self-recognition" which bars two electrons with a common set of quantum numbers--one of which is spin--from a single atom might also restrict the phenomenon of interference fringes Coy which waves are distinguished from particles) to entities of like spin?

* In the most precise experimental test to date, researchers found no evidence for any violations of the Pauli exclusion principle (137: 287).
