Pauli exclusion principle
The Pauli effect is not related to the Pauli exclusion principle, which is a bona fide physical phenomenon named after Pauli. However the Pauli effect was humorously tagged as a second Pauli exclusion principle, according to which "a functioning device and Wolfgang Pauli may not occupy the same room". Pauli himself was convinced that the effect named after him was real. Pauli corresponded with Hans Bender and Carl Jung and saw the effect as an example of the concept of synchronicity.
