Not much.

Because the theories have influence far out of proportion to their actual track record, yes.

> low confidence in experiments, imo

You can't run controlled experiments in either of those fields, so it's not so much a matter of low confidence in experiments as no ability to do them in the first place. There are some general patterns that can be picked out, but both disciplines deal with non-repeatable human situations that require non-repeatable human judgments to deal with them. Even to call them "sciences" is a stretch, except on a very general usage of the term "science" to basically mean "something people study".
