We show how a dynamical Majorana mass for a fourth family left-handed neutrino can make a significant negative contribution to the electroweak correction parameter T\ensuremath≡\frac\ensuremathΔ\ensuremathρ\ensuremathα without making a large contribution to S or U. We also comment on other possible contributions to T in the context of dynamical symmetry breaking.
