If you probe a system to observe it, it actually becomes a POVM rather than the usual Von-Neumann measurement described by an operator.
That's why my link that starts from POVM's in the actual axiom is a better approach and you see immediately collapse has nothing to do with anything, neither does a conscious observer or many of the other things people get confused about.
Thanks

Pages 20 and 21 of this article, http://www.quantum.umb.edu/Jacobs/QMT/QMT_Chapter1.pdf, appear to prove that electrons in the double slit experiment must be thought of as actually being in the superposition of two states at the same time. He uses the interference term in the probability distribution to justify his proof. I would be very much interested if someone(s) with more knowledge than me can read pages 20 and 21 and provide a technical review. (I have read other articles where it is stated that the interference in the double slit experiment comes from the fact that the electrons travel different path lengths when going through the different slits caused by the differing distance the electron is from each slit)
