Title: Gravitational Corrections to Running Couplings

Abstract:  Robinson and Wilczek popularized the study of how gravity modifies the running of the gauge coupling constants. This subject has since then had a
controversial history. The issues are illuminating, illustrating some of the distinctive features of effective field theory. In the end, I will argue
against the whole enterprise. I will also discuss the idea of a running Newton's constant G_N within due to gravity itself.
