The Pauli effect is a term referring to the apparently mysterious, anecdotal failure of technical equipment in the presence of Austrian theoretical physicist Wolfgang Pauli. The term was coined using his name after
numerous instances in which demonstrations involving equipment suffered technical problems only when he was present.
The Pauli effect is not to be related with 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 that
a functioning device and Wolfgang Pauli may not occupy the same room.[1] Pauli himself was convinced that the effect named after him was real.[1] Pauli corresponded with Hans Bender and Carl Jung[1] and saw the effect as an example of the concept of synchronicity.
