  The recent measurement of the muon anomalous magnetic moment a_\mu\equiv
(g-2)_\mu/2 by the Fermilab Muon g-2 experiment sharpens an earlier discrepancy
between theory and the BNL E821 experiment. We examine the predicted \Delta
a_\mu\equiv a_\mu(exp)-a_\mu(th) in the context of supersymmetry with low
electroweak naturalness (restricting to models which give a plausible
explanation for the magnitude of the weak scale). A global analysis including
LHC Higgs mass and sparticle search limits points to interpretation within the
normal scalar mass hierarchy (NSMH) SUSY model wherein first/second generation
matter scalars are much lighter than third generation scalars. We present a
benchmark model for a viable NSMH point which is natural, obeys LHC Higgs and
sparticle mass constraints and explains the muon magnetic anomaly. Aside from
NSMH models, then we find the (g-2)_\mu anomaly cannot be explained within the
context of natural SUSY, where a variety of data point to decoupled
first/second generation scalars. The situation is worse within the string
landscape where first/second generation matter scalars are pulled to values in
the 10-50 TeV range. An alternative interpretation for SUSY models with
decoupled scalar masses is that perhaps the recent lattice evaluation of the
hadronic vacuum polarization could be confirmed which leads to a Standard Model
theory-experiment agreement in which case there is no anomaly.
