Abstract
We emphasize that standard quantum theory (SQT) is incomplete because it doesn't describe what is experimentally observed, namely events, nor does it satisfactorily define the circumstances under which events may occur. Simple models are given (all of which have the same density matrix evolution) to illustrate schemes which claim to complete SQT. It is shown how the model based upon the Continuous Spontaneous Localization (CSL) theory, in which an individual statevector undergoes "True Collapse," gives a satisfactory description of events. It is argued that various "decoherence" based approaches, illustrated by models in which a density matrix undergoes "False Collapse," do not satisfactorily resolve these problems of SQT.
