I'm just confused by your distinction between mutation and other reasons to fall into different self-consistent attractors. I could wind up in one reflective equilibrium than another because I happened to consider one rational argument before another, because of early exposure to values, genetic mutations, infectious diseases, nutrition, etc, etc. It seems peculiar to single out the distinction between genetic mutation and everything else. I thought 'mutation' might be a shorthand for things that change your starting values or reflective processes before extensive moral philosophy and reflection, and so would include early formation of terminal values by experience/imitation, but apparently not.
