One thing that did really help in my situation was learning about my parents' strengths.
You said, "we regularly tell her that we're wrong all the time, and that it's OK." In addition, do you also clearly show her your abilities?
Do you show your DD ways in which you make excellent decisions (e.g. at work, in financial planning, in making a will, in helping a friend)? Do you show her your mastery of domains with which she is unfamiliar? Does she feel you are an authority on good choices (as well as mistakes)?
Seems like a good idea. I did teach her how to persevere, and use illustrations from my life and work, and I think it got through. She did mention it once or twice later.
It's an interesting perspective that will require some more thought and intentionality, but I'm definitely going to pursue it.
