I have found that audiences genuinely appreciate when you speak powerfully and simply; you can rephrase something like
> "we're considering many different possible pathways, and some of them we're finding are less optimized to meet our institutional goals"
to
> "we're not sure what to do, and so far most of the ideas we thought of were pretty bad"
and your audience laughs and leans in. I try to emulate that Jobs-ian style at work and a lot of people seem to like my presentations.
I think people really like it when someone takes the responsibility of standing up and saying "let's not overcomplicate this, I'll take responsibility for making the decisions and I don't spend a lot of time trying to hide my real level of knowledge. In fact, I may know less than some of you." (Even if that's probably not true.)
Another good (albeit hyperbolic) example of this is Jeremy Irons' speech near the end of Margin Call (2011) where he tells the junior analyst to "speak to me as if I am a very small child, or possibly a golden retriever." In fact, that's also an explicit direction given to flight controllers at NASA during their training.
