My list of other intellectual fields from which identity might learn:
- economics - if the availability of a particular identity attribute grows scarce in the marketplace (because of privacy or legislative factors), does it become more valuable? Can you even assign a value to a particular attribute?
- game theory - does the Prisoner's Dilemma bear on social network dynamics? Or on the standardization process?
- evolutionary science- is the battle between phishers & security experts comparable to the 'arms races' that develop between predators & prey? If so, who is the prey?
- history - could the 'identiverse' be carved up into non-overlapping regions of protocol dominion as agreed to by Spain annd Portugal in the 15th century Treaty of Tordesillas, i.e. SAML/WS-Fed get the enterprise, OpenID/Cardspace are ceded consumer space? Who would play the monopoly busting Sir Francis Drake?
