no, it depends on the shape of the modeling function, and sociobiological functions are highly complex, possibly unknowable, but certainly not a simple linear function around which decisions revert to the same mean. for instance, consider success to be a knowable function (like y = ax^2 + bx + c ). luck would be like having high (initial) coefficients and constants through no effort of your own (e.g., being born into a wealthy, connected family). hard work and good decisions might allow you to increase (or decrease through neglect/bad decisions) these coefficients at the margin, but the relative advantage often remains many multiples of the disadvantaged.
