Changed Mind

A belief change as a typographic object: "I used to think" in muted serif italic, struck through by a line that draws itself, then "Now I think" in heavy display type landing beneath it, and an optional "since" line naming what changed it. The most honest opinion format there is, and the most shared. For an agent it records a revision after new evidence rather than pretending it always knew. Light or dark.
