Unreasonable Effectiveness of Higher Derivative Supergravity in AdS_{4} Holography.

We study four-derivative corrections to four-dimensional N=2 minimal gauged supergravity controlled by two real constants. The solutions of the equations of motion in the two-derivative theory are not modified by the higher-derivative corrections. We use this to derive a general formula for the regularized on-shell action for any asymptotically locally AdS_{4} solution of the theory and show how the higher-derivative corrections affect black hole thermodynamic quantities in a universal way.
