Ah, but! The “true you” and the “substance of your message” are two completely different things, and clever use of cognitive dissonance can be used as a tool to mask the former with the latter. It is used to draw attention, to override logical reasoning. Politics as we know it is painfully dependent on this tactic. Visual artists also have to strike balance between photo-realism and subjective “likeness”, which are not always compatible. I’ve seen discussed in a few places the notion that dissonance isn’t simply a quirky malfunction in our mental processing, but rather an integral part of its machinery. The upshot being that it’s less about whether there is dissonance in your message, than about whether it’s being properly harnessed. Yes/no?

I could go on about this at much greater length, but I’ll cut the rant here.
