Abstract:  
We show that the attractor mechanism for generic black hole is a consequence of doublehorizon. Investigation of equations of motion shows that in the case of doublehorizon black holes, the dynamics of geometry, scalars and gauge fields at the horizon decouples from the rest of the space.
In the general case, the value of the fields at the horizon satisfies a number of differential equations of functions of the θ coordinate.
We show this for the case of rotating and nonrotating electrically charged black holes in the general two derivative theories of gravity and f(R) gravities and theories with cosmological constant.
