Query: Getting chirality right: single scalar leptoquark solutions to the
  $(g-2)_{e,\mu}$ puzzle   We identify the two scalar leptoquarks capable of generating sign-dependent
contributions to leptonic magnetic moments, $R_2\sim (\mathbf{3}, \mathbf{2},
7/6)$ and $S_1\sim (\mathbf{3}, \mathbf{1}, -1/3)$, as favoured by current
measurements. We consider the case in which the electron and muon sectors are
decoupled, and real-valued Yukawa couplings are specified using an up-type
quark mass-diagonal basis. Contributions to $\Delta a_e$ arise from
charm-containing loops and $\Delta a_\mu$ from top-containing loops -- hence
avoiding dangerous LFV constraints, particularly from $\mu \to e \gamma$. The
strongest constraints on these models arise from contributions to the Z
leptonic decay widths, high-$p_T$ leptonic tails at the LHC, and from
(semi)leptonic kaon decays. To be a comprehensive solution to the
$(g-2)_{e/\mu}$ puzzle we find that the mass of either leptoquark must be
$\lesssim 65$ TeV. This analysis can be embedded within broader flavour anomaly
studies, including those of hierarchical leptoquark coupling structures. It can
also be straightforwardly adapted to accommodate future measurements of
leptonic magnetic moments, such as those expected from the Muon $g-2$
collaboration in the near future.
