"Humans have many more options before them than they currently believe...but what to do with too much information is a great riddle of our time", according to Theodore Zeldin.
Nudge has been in vogue in recent years, with its ideas about "choice architectures" and driving people towards pro-social behaviours (including, as I've witnessed myself at Brussels Airport, painting a fly on urinals to help us poor males pay better attention to where we point Percy!)
(Persuasive technology and captology seem to cover much the same ground.)
Can we be confident, however, that nudging is really that far up the food chain from subliminal advertising?
At very least, we need to be open about which behaviours we wish to encourage and surely the best way to start would be by engaging more people about what those behaviours and related shared values might be?
