Back on 7 September of last year, I did a talk at TEDxUmhlanga, on the topic of 'Inner Conflict'. Some of what I spoke about is relevant to the common currency topic, in the sense that it concerns a reward-based explanation for inconsistency in choice patterns. (Inconsistency might otherwise be taken as an argument against a common currency.) The talk is embedded below.
(If you've seen the video of my talk at 'Thinking Things Through' in December, you might be wondering whether I ever wear anything else. Yes. Yes, I do.) I've also been doing some more serious research work on this topic, and hope to have more things to post really soon.
