ABSTRACT
This chapter presents the knowledge representation and reasoning needed to pass reasonable person tests centred on fairness and autonomy. The test cases presented are Dive Boat, Landlord, Gold Mine, The Rocks, Viking at the Door and Mars Rescue. Key elements used to pass these test cases are quantifications of ‘moral force’, a lexical ordering between needs and wants (needs ‘trump’ wants) and ‘hectocritical’ weightings attached to risk assumption and desert (innocence). Unfairness can be understood in terms of the transfer of a benefit or burden without consent of the ‘losing’ party (i.e. the party that loses the benefit or becomes subject to the burden).
