How would you go about introducing ideal objects into Figure 21-2?
It is argued that people are not consciously aware of which dimensions they are employing to make similarity or even preference judgments. Further, respondents may base judgments on attributes to which they are unwilling to admit. The use of nonattribute data in MDS is, thus, rather like motivation
