OK. Similar situations may occur for ordinary correlations.
E.g., assuming that we get a high correlation coefficient between two
series of observations (physical phenomenons A and B), it could mean:
(1) A acts on B or A is the cause of B
(2) B acts on A or B is the cause of A
(3) C (to be identified) acts or is the cause of both A and B.
These situations may be cumulated.
The situation (3) is sometimes neglected by scientists, and also
sometimes by dishonest people willing to "prove" something.
E.g. when the weather is fine (high temperatures), people drink
more in the bar, and the time needed to dry washed clothes is
reduced. But of course, I shall not tell to my wife that I have
to drink more in order to get the clothes dried faster.
Coming back to particles, a potential C will cause effects on particles
A and B when A and B exist, although A and B are not themselves interacting.
