Intelligence Citations Bibliography for Articles Related to IQ Testing
You may find it helpful while reading or editing articles to look at a bibliography of Intelligence Citations, posted for the use of all Wikipedians who have occasion to edit articles on human intelligence and related issues. I happen to have circulating access to a huge academic research library at a university with an active research program in these issues (and to another library that is one of the ten largest public library systems in the United States) and have been researching these issues since 1989. You are welcome to use these citations for your own research. You can help other Wikipedians by suggesting new sources through comments on that page. It will be extremely helpful for articles on human intelligence to edit them according to the Wikipedia standards for reliable sources for medicine-related articles, as it is important to get these issues as well verified as possible. -- WeijiBaikeBianji (talk) 21:01, 30 June 2010 (UTC)
Quotation by Carroll
I find this quotation by Carroll problematic:
- "Guilford's SOI model must, therefore, be marked down as a somewhat eccentric aberration in the history of intelligence models; that so much attention has been paid to it is disturbing, to the extent that textbooks and other treatments of it have given the impression that the model is valid and widely accepted, when clearly it is not."
If it has received so much attention and textbooks treat it as widely accepted, Carroll's claim that it isn't seems not to have that much merit. In the passage in question he claims that there are several analyses of Guilford's work showing that it is invalid, but one cannot conflate validity (which is not a rarefied popularity contest) and acceptance (which is). I haven't read the whole of Carroll's book (just the pages around this quote on google books). Could someone clarify what Carroll's evidence of non-acceptance is, so that we can surround the quote with more context? VsevolodKrolikov (talk) 13:22, 31 October 2010 (UTC)
- Thanks for asking the specific question on acceptance of Guilford's hypothesis. I'll remember to look for information about that as I dig into sources. Just as a quick response here, my impression of the literature is that Guilford's approach was mentioned often in textbooks until CHC theory really took hold, but hardly elaborated by anyone but Guilford himself. But I'll double-check the sources to make sure about that. -- WeijiBaikeBianji (talk, how I edit) 14:57, 31 October 2010 (UTC)
I wrote the section based on what can be read of Carroll's book online and on Jensen's discussion of Guilford in The g Factor. Jensen says that Guilford's model "proved to be an unconvincing and short-lived challenge--one might say pseudo-challange--to g theory. Carroll's summary of the SOI model fairly represents the viewpoints of most present-day researchers in this field: 'Guilford's SOI model must, therefore, be marked down as a somewhat eccentric aberration etc.'"
Citing Alliger (1988), Jensen says that the mean correlation between Guilford's supposedly uncorrelated data sets is, after proper corrections, actually .45. Carroll also says that he has reanalysed much of Guilford's data, finding no support for the SOI model. Carroll cites strong criticisms of Guilford from a number of prominent psychometricians.
Carroll, Jensen, Horn, and others have also taken Guilford to task for using a technique known as targeted orthogonal rotation, where factors are defined before the data are analysed. Guilford assumed a priori that the SOI model is correct, and analysed data from that perspective.
Nicholas Mackintosh's 1998 book "IQ and Human Intelligence" is also very dismissive of Guilford (p. 214-215):
Guilford's theory is highly convoluted and implausible, and I haven't seen it defended in any recent journal articles or books. I see no reason to think that Jensen, Carroll, Mackintosh, Brody and others are not correct when they say that the SOI model has little support among experts, but if you have some recent source that suggests otherwise, please cite it.--Victor Chmara (talk) 17:36, 31 October 2010 (UTC)
- I'm not challenging the statement that Guilford's model is not widely accepted. I just think the quote as inserted lacked explanation, and appeared to be contradictory. It looks better now that there is another source. Can I ask why you put the Jensen objection above the one by Carroll? It would seem to make more sense to place the general objections to Guilford's methods before specific pro-g factor opinions.VsevolodKrolikov (talk) 04:55, 1 November 2010 (UTC)
