  1. Can decisions under ignorance be transformed into decisions under uncertainty?

I'd add a comment on Jaynes' solution for determining ignorance priors in terms of transformation groups.

I'd say that there's no such think as an "ignorance" prior - priors are set by information. Setting a prior by symmetry or the more general transformation group is an assertion of information.
