  What is called "orthodox" quantum mechanics, as presented in standard
foundational discussions, relies on two substantive assumptions --- the
projection postulate and the eigenvalue-eigenvector link --- that do not in
fact play any part in practical applications of quantum mechanics. I argue for
this conclusion on a number of grounds, but primarily on the grounds that the
projection postulate fails correctly to account for repeated, continuous and
unsharp measurements (all of which are standard in contemporary physics) and
that the eigenvalue-eigenvector link implies that virtually all interesting
properties are maximally indefinite pretty much always. I present an
alternative way of conceptualising quantum mechanics that does a better job of
representing quantum mechanics as it is actually used, and in particular that
eliminates use of either the projection postulate or the eigenvalue-eigenvector
link, and I reformulate the measurement problem within this new presentation of
orthodoxy.
