 Qualitatively at least, since spontaneous collapse produces localisation, the effect appears formally similar as in some of the models of decoherence. But we have ‘true’ collapse instead of suppression of interference, and spontaneous collapse occurs without there being any interaction between the system and anything else. In cases in which the decoherence interaction indeed also takes the form of approximate position measurements, the relation betweeen spontaneous collapse and decoherence presumably boils down to a quantitative comparison. If collapse happens faster than decoherence, then the superposition of components relevant to decoherence will not have time to arise, and insofar as the collapse theory is successful in recovering classical phenomena, decoherence plays no role in this recovery. Instead, if decoherence takes place faster than collapse, then the collapse mechanism can find ‘ready-made’ structures onto which to truly collapse the wave function.
