Correction: should had said "mis-diagnosed" though I'm sure everyone got it.
Diagnostic thinking can go beyond projecting specific chains of cause and effect onto to something to explain it. In the sense that dissonance illustrates something being out of place, we could measure novelty by noticing one part fails to be explained by those around it. That part should show as a mistake or a misinterpretation and could as well indicate emergence? Do emergent thoughts need to be novel and out on their own? If they slipped in as connections between things we knew but previously couldn't connect they would not necessarily be noticible.
