Is there a historical example or does anyone have an anecdote of some crunch time where the CEO blowing hot air was the best thing for morale? Compared to what I might think a lot of us would prefer in many cases, which might be an honest assessment & making us part of the journey to overcome whatever adversity.

Not exactly?

Let's say there are a thousand people there at the town hall. You don't want any of them to leave upset, or even concerned. But they each have different things that will make them concerned and upset. So there are maybe 10,000 tripwires out there, and you don't want to trip any of them.

So you're not being dishonest, exactly. You're being nonspecific. You don't want to get down in the weeds and nail down the answer too tightly, because you may trip someone's tripwire. (And also because it would take to long.) So you say something true but not very specific.

(I mean, there can be dishonesty, too, but that's a different thing. Smooth vagueness can still be honest, just unsatisfyingly vague.)
