Yes, you are quite correct and I thank you for correcting my error. I

should have said that the probability of finding 2 electrons x distance

apart is the intensity of the complex quantum wave function F(x); that

is to say P(x) = [F(x)]^2 . However it remains true that the imaginary

part of that complex function is the source of a lot of quantum

weirdness. It’s also still true that if we exchange the positions of the

electrons then x1- x2 =x becomes x2 – x1 = -x but according to the

Identity of Indiscernibles exchanging identical things does nothing

detectable so P(x) = P(-x). And then away we go. Anyway thanks again.
