There’s probably something to be gained by investigating this further, but i would guess that most cases of value drift are because a loss of willpower and motivation, rather that an update of one’s opinion. I think the word value drift is a bit ambigious here, because i think the stuff you mention is something we don’t really want to include in whatever term we use here.
Now that i think about it, i think what really makes the difference here are deeply held intuitions about the range of our moral duty and so for which ‘changing your mind’ doesn’t alway seem appropriate.
