American economist Richard Thaler, who discusses his book Nudge.
BBC Radio 4 – Start the Week – Mon, 23 Mar 2009 http://www.bbc.co.uk/iplayer/episode/b00j67mh/Start_the_Week_23_03_2009/ The principle could have relevance to design interpretation by stakeholders, but its’ premise is somewhat old-hat – e.g. the flies in the urinals in Schiphol airport. Actually, now that I’ve listened to it again – it’s not that relevant. A bit basic aside from the “nudge” buzzword. The concept of a snag or a bump in an economist’s model, or in a stakeholder’s perception / attention is interesting, however. They also talk about a “nudge” as if it’s a perversion of an intended behaviour pattern by users: maybe analogous to battles against architectures of control in building design and process design, perhaps???
