We discuss the conditions under which renormalization-group methods can imply Bjorken scaling for deep-inelastic structure functions. We prove and refine a conjecture of Parisi's concerning the high-spin behavior of anomalous dimensions in order to show that in most theories Bjorken scaling is possible only if the renormalization group has a fixed point at the origin of coupling-constant space.
