 The bare quantity \(g_0\) can be regarded as a black box that sums up effects associated with energies beyond the cut-off scale \(\Lambda\) where unknown effects must be taken into account. Viewing a theory as an effective field theory means viewing it as a self-contained description of phenomena up to the cut-off scale \(\Lambda\). This perspective suggests that one may only consider an effective theory as natural if the physical quantity \(g_{\Fphys}\) can be of its actual order of magnitude without any need for a delicate cancellation between \(g_0\) and \(\Delta g\) to many orders of magnitude. Since the bare quantity \(g_0\) sums up information about physics beyond the cut-off scale \(\Lambda\), such a delicate cancellation between \(g_0\) and \(\Delta g\) would mean that the order of magnitude of the physical quantity \(g_{\Fphys}\) would be different if phenomena associated with energies beyond the cut-off scale \(\Lambda\) were slightly different.
