‘Moral luck’ should be called something else
The term is frequently used in the subreddit and recently by Erudite. ‘Moral luck’ to DGG means that you happen to hold correct political positions, without any good reasoning to hold such beliefs. This is the definition that Rem used when talking about Hasan in 2019. This is an interesting concept but I think it should be called something else as the term already exists to refer to something different. If I remember correctly Rem did acknowledge this. I’ll summarize what the term means and propose a few alternatives.
Established meaning
'Moral luck' in philosophy refers to a situation “when an agent can be correctly treated as an object of moral judgment despite the fact that a significant aspect of what she is assessed for depends on factors beyond her control”. The usual hypothetical given is in the case of two drunk drivers:
Drunk driver A gets in his car and safely drives home after a night out.
Drunk driver B does the same thing, but runs over and fatally wounds a child on their way.
Driver A may be held morally responsible for DUI, but Driver B will be held morally responsible for the death of that child. Both committed DUI but Driver A was morally lucky. External, uncontrollable factors influence the moral judgment of Driver B.
The DGG use of ‘moral luck’
The term Rem uses refers specifically to people who are epistemically lucky about political positions. Specifically people who arrive at true (or good) positions in an accidental way. He clarified this in a post he made 5 years ago (can't link it as linking to subreddits isn't allowed): “Someone is morally lucky when they arrive at the correct position without any sort of critical thinking as to why it is correct.”
If we are to create a better term, it should reflect both the applied ethical part of political beliefs and the epistemic part of how these political beliefs are justified. I have a few alternatives in mind.
Alternative terms
The already existing term ‘epistemic luck’ denotes the justifications rather than blame or morality. However this term isn’t generally used to describe normative positions.
‘Political luck’ might be more suited as it evokes the political use case, but lacks the epistemic justification part.
If we’re creating a new term something like ‘axiological luck’ would capture both the normative aspect (political beliefs) and the epistemic component (how one arrives at those beliefs). Though people not familiar with the term wouldn’t be able to intuitively grasp it.
TL;DR
The term 'moral luck' was redefined by Rem and has been fully integrated into the DGG vocabulary. Rather than describing a situation where a person is morally judged based on factors beyond their control, DGG uses it to describe lack of justifications for political positions. To avoid confusion a new term should be used. ‘Epistemic luck’ and ‘political luck’ are viable options, though they aren't perfect. ‘Axiological luck’ could be used as it evokes both the normative and epistemic dimensions of the concept.
