ETHICS IN COMPUTER-AIDEDDESIGN: A POLEMIC* JOHN S. GERO Department of Architectural Science University of Sydney, Australia formerly Harkness Research Fellow Department of Architecture University of California, Berkeley ABSTRACT I t is one of the d i f f i c u l t i e s of the s c i e n t i f i c approach to problem solving that the variables need to be defined at the beginning of the investigation. This is further exacerbated when computer based techniques are applied because of the need to define variables e x p l i c i t l y . Current problem solving is directed to handling only well defined problems in which certain variables are assumed to be exogenous - the educational system schools people in methods for manipulating problems at this level. I t appears that computer-aided design systems, in general, have not been able to incorporate any adequate value systems within them nor have they been able to provide a means of examining the problem in an ethos borader than" the one defined at the outset. these d i f f i c u l t i e s are considered within
