The quark and lepton mass matrices possess approximate flavor symmetries. Several results follow if the interactions of new scalars possess these approximate symmetries. Present experimental bounds allow these exotic scalars to have a weak-scale mass. The Glashow-Weinberg criterion is rendered unnecessary. Finally, rare leptonic {ital B} meson decays provide powerful probes of these scalars, expecially if they are leptoquarks.
