An interesting case of what I would call visual deliberation, in the broad sense of “the use of visual aids to support deliberative processes”:
The carton obviously presents four distinct arguments, using a mix of verbal, pictorial and spatial elements or mechanisms.
However the main argument made by the cartoon is that the arguments against wind power are weak as compared with the arguments against nuclear, oil and coal. This argument is not explicitly given, whether verbally or pictorially; it is a kind of “conversational implicature” of the presenting of the four arguments.
