Thanks for a great essay and for your effort to tackle the "how" question about shaping human behavior in ways that will support better long term decision-making. I think this can help, but I'm not sure how much the proposed solution will be able to accomplish. Priority maps and personal preferences are not, at least not yet, based on hard science - as I understand it they can be measured through surveys relative to community norms, but I'm not sure they are useful in shaping community norms. As I discuss in my essay the Tip of the Spear, a community (networked as an institution) needs to sustain shared moral values and cooperative behaviors....
On a different note, how do we protect individual data from being "mined" for commercial purposes rather than social ones? The internet started as an academic initiative - but is not longer subject to those community norms. Moreover, immense volumes of data on social media, personal preferences in entertainment and purchasing practices are being collected and used to tailor what we see (or buy) without our knowledge or informed consent. How could the very valuable data from priority maps be collected and shared without becoming additional commercial fodder?
