to map or not to map

A reader writes to question whether the mental map (below) on climate change really helps understanding or simply just reinforces,

'a way of thinking that communicates quickly, but without depth ... for someone, coming to it from the outside, it could represent a way of thinking that is part of the problem.'

For example, the reader recommends going back to Debategraph and clicking on the 'arts' bubble: there is only one entry (so far). It's for 'Hamlet's existential dilemma' and quotes three lines from the 'To be or not to be' soliloquy. And that's the sum total under 'arts'.
