I think I agree on the core idea, but if you extrapolate this into font selection, for example, you would rather pick Comic Sans for more "strategic" and abstract projects? ;)
I've certainly used comic sans intentionally when presenting data. Much of this depends on audience too. A corporate board meeting is quite different from an activity with a group of rowdy 8-year-olds from a presentation in a university class from a tight-nit group of friends launching a startup.
Some comes down to power hierarchy too. Presenting up, I'm much more likely to try to appear professional. Presenting down, I go for approachable.
(Clearly you're joking) but this isn't an extrapolation. Lines that make up characters in a font don't have any semantic meaning related to the words. Lines in a graph do have semantic meaning related to the data they represent.
[edit] maybe you could make this argument for a language like Chinese. At least for characters with semantically meaningful radicals.
