The velocity of a point x in configuration space is defined as the standard probability current j(x) divided by the probability density P(x). However, this standard'' j is in fact only one of infinitely many that transform correctly and satisfy /dot P + /del . j=0. In this article I show that there is a unique j that can be determined experimentally as a weak value using techniques that would make sense to a classical physicist. Moreover, this operationally defined j equals the standard j, so, assuming /dot x = j/P, the possible Bohmian paths can also be determined experimentally from a large enough ensemble. Furthermore, this approach to deriving BM singles out x as the hidden variable, because (for example) the operationally defined momentum current is in general incompatible with the evolution of the momentum distribution. Finally I discuss how, in this setting, the usual quantum probabilities can be derived from a Bayesian standpoint, via the principle of indifference. en_US dc.description.peerreviewed Yes en_US dc.description.publicationstatus Yes en_AU dc.format.extent 243245 bytes dc.format.mimetype application/pdf dc.language English en_US dc.language.iso en_AU dc.publisher Institute of Physics Publishing en_US dc.publisher.place Online en_US dc.publisher.uri http://www.iop.org/EJ/journal/NJP en_AU dc.relation.ispartofstudentpublication N en_AU dc.relation.ispartofpagefrom 165-1 en_US dc.relation.ispartofpageto 165-12 en_US dc.relation.ispartofjournal New Journal of Physics en_US dc.relation.ispartofvolume 9 en_US dc.rights.retention Y en_AU dc.subject.fieldofresearchcode 240201 en_US dc.title Grounding Bohmian mechanics in weak values and bayesianism en_US dc.type Journal article en_US dc.type.description C1 - Peer Reviewed (HERDC) en_US dc.type.code C - Journal Articles en_US gro.rights.copyright Copyright 2007 Institute of Physics Publishing.
