CHC model of intelligence is mainstream--Woodcock (1990) and McGrew (2009) both #1

I was searching through some journals tonight and discovered that Dr. Richard Woodock's seminal 1990 article, "Theoretical foundations of the WJ-R measures of cognitive ability", is the #1 cited article in the Journal of Psychoeducational Assessment (see image below...click to enlarge)

This article is not just about the WJ-R. The article used the then Gf-Gc based WJ-R special study data files to conduct a series of joint CFA with all the major intelligence tests. The most important insight was a mapping of all major IQ tests as per the major broad abilities of what is now call the CHC model of intelligence. It gave birth to the concept of CHC cross-battery assessment. It was a major influential tipping point article in the evolution of the CHC model; primarily by bridging theory and assessment practice. I have written about this important seminal Woodcock paper in McGrew (2005) and Schneider and McGrew (2012). This is also relfected in the CHC Timeline project, a portion which is presented below (click image to enlarge)

Couple this with the fact that my invited editorial on CHC theory, in the journal Intelligence, is the #1 cited article since 2009 in that journal, and it is my conclusion that CHC theory is now part of mainstream psychology and theories of intelligence.

The tipping point has passed...the CHC taxonomy is now mainstream. Further evidence is the revision or development and analysis of most all intelligence theories as per CHC theory (see the stellar research of Keith and Reynolds and others...here...and here.

CHC theory tipping point passed: Inroads in mainstream intelligence research

In 2005 I unilaterally claimed that the Cattell-Horn-Carroll (CHC) theory of cognitive abilities had reached the "tipping point" in school psychology--it had become the consensus psychometric framework from which new intelligence tests are developed, old ones are revised, and non-CHC batteries are analyzed. Later in 2007 I again revisited my "tipping point" claim by analyzing the use of keywords in the National Association of School Psychologists (NASP) general service listserv. At that time I concluded that the actual tipping point occurred (in school psychology) sometime between 2001 and 2003.

Today I decided to see if the school psychology CHC tipping point had spilled over and gained traction in more mainstream psychology. In particular, I was interested in how often the terms "CHC" or "Cattell-Horn-Carroll" were present in articles in THE premiere journal outlet for the heavy hitters in the field of intelligence research--the journal Intelligence.

So...I went to the journal's web page and used the above two terms/phrases and asked for a search of "all fields" for the journal. Below is what I found.

Prior to 2004 there was NOT ONE article in Intelligence that mentioned CHC or Cattell-Horn-Carroll theory. However, since 2004 there have been at least 21 publications that reference this model of intelligence.

It is my opinion that CHC theory clearly reached a tipping point somewhere between 2001-2003 and it is now making strong inroads as one of the most supported models of the structure of human intelligence in the field of intelligence research.
