One way to characterize dispositions is to take them to be reducible t
o categorical properties plus experimental arrangements. We argue that
this view applied to Bohm's ontological interpretation of quantum the
ory provides a good picture of the unremarkable nature of spin in that
interpretation, and so explains how a simple realism of possessed val
ues may be retained in the face of Kochen and Specker's theorem. With
this in mind we discuss Redhead's influential analysis of Kochen and S
pecker's theorem which does not appear to allow for the above view.
