Talk:Diamond of opposites

message: A search of psycinfo, eric and biomed produced zero hits for "diamond of opposites." The concept may be interesting but the article should be deleted on the grounds that it is research, and not encyclopedic.

replies: text: The article states that “Diamond of opposites is a two-dimensional scaling method, measuring positive and negative response to a statement”. As presented, this is clearly false. The so-called diamond represents a confused use of continua to form two-dimensional space. This is evident in the statement in the quote above: ‘(a) bottom (weak feelings of both attraction and repulsion), (b) top (strong contradictory feelings of both attraction and repulsion), (c) left (attraction), and (d) right (repulsion)’. Why? If left (negative on x-axis) represents attraction and right (positive on x-axis) represents repulsion, why should the top centre (0 on x-axis) represent “strong contradictory feelings of both attraction and repulsion”. This implies that the left and right regions have one meaning in the centre but an entirely different meaning at the top or bottom, which is entirely inconsistent. An analogy would be having left and right represent small and large mass when y-coordinates are near 0 but represent simultaneously small and large mass when y-coordinates are large positive! This is nonsensical, and indicates a confused use of continua. I can elaborate further if required. BTW, the problem is not in hypothesizing that, for example, love and hate may not mutually exclusive. A researcher could hypothesize that 'don't care less' is the other end of the spectrum for both love and hate, and accordingly attempt to scale love and hate separately. This is a different issue. I've removed it from psychometrics category and will remove it from scaling methods because there are no citations indicating this has been recognized in psychometrics as a basis for scaling. I'd be very surprised if there were unless the 'diamond' is being misrepresented in the article and quote appearing above. Holon 10:58, 6 February 2006 (UTC)
replies: text: O! I see now! You did not understand this 2-dimensional plot. It is like adding vectors. Lakinekaki 16:40, 6 February 2006 (UTC)
replies: text: I understood perfectly, as indicated yesterday Lakinekaki, and the attempt to use 2-dim space is precisely the problem. It is not 'like adding vectors' because there are no well-defined vectors to begin with. If you disagree, please provide information to clarify, preferably with references.

text: Is it 'just an x,y plot of two variables' though? If so, why are responses restricted to a 'diamond' in a cartesian plane rather than being anywhere? In semantic differential items, the two variable are semantic opposites, whereas it is totally unclear from information provided so far what two continua are supposed to represent. I'm not raising this to argue for deletion, I want the reader to be aware of the issues. Perhaps they can be clarified? Holon 02:13, 7 February 2006 (UTC)

text: --Thx for the clarification Nesbit. The continua are not represented according to the usual convention in which one axis is horizontal, the other vertical. It is perfectly fine not to use convention, particularly to make a point, but this should be pointed out to the reader otherwise it is confusing. The diagram makes this clear, so I have made it larger. Note the diagram has 0 to 10 on axes whereas the example refers to 1 to 10. Not a big deal but could be confusing.
