"Alice is a banker" is a simpler statement than "Alice is a feminist banker who plays the piano.". That's why the former must be assigned greater probability than the latter.

Complexity weights apply to worlds/models, not propositions. Otherwise you might as well say:

"Alice is a banker" is a simpler statement than "Alice is a feminist, a banker, or a pianist.". That's why the former must be assigned greater probability than the latter.

Agreed. Instead of complexity, I should have probably said "specificity".

"Alice is a banker" is a less complicated statement than "Alice is a feminist, a banker, or a pianist", but a more specific one.
