Fine-tuning of the weak-scale was traditionally measured by the Barbieri-Giudice measure $$ \Delta = \frac{\partial\ln M_Z^2}{\partial \ln m_{\textrm{soft}}} $$ In a series of papers [1, 2, 3, 4, 5], I have argued that our intuitve ideas about fine-tuning are captured formally in Bayesian statistics.
