I agree with Brian: the anti skating mechanism on my Grace 707 also works to rotate the arm outward, towards the edge of the record.  So the skating force (actually torque) it is fighting must be the other way.  It can be explained this way: the friction on the stylus is tangent to the record groove and tends to pull the stylus forward, in the direction the record is turning.  The vector component of this force along the arm is cancelled by the rigid constraint that the arm doesn't stretch, and the remaining component is clearly inward.
