I've come up with a litany that would be to instrumental rationality what the Litany of Tarski is to epistemic rationality, expressing the sentiment in "Newcomb's Problem and Regret of Rationality":
If I would be better off taking both boxes,
I desire to choose to take both boxes;
If I would be better off taking only box B,
I desire to choose to take only box B;
Let me not become attached to decision I may not want.
This doesn't help in the general case. See, for example...
If I would be better giving Parfit $100,
I desire to choose to give Parfti $100;
If I would be better off keeping my $100,
I desire to choose to keep my $100;
Let me not become attached to decision I may not want.
A step closer to accurate (albeit in need of elegant wording) would be:
If I would be better off having precommited to taking both boxes
I desire to choose to take both boxes...
“Would” has to be interpreted à la Gary Drescher in Good and Real.
A wording slightly less inelegant than yours would be "If I am better off being the kind of person that gives Parfit $100..."
