Schooling might reduce the effect of some abilities required in the Matrix Reasoning Task. In the higher educational levels, Matrix Reasoning would be a purer indicator of the general factor. <br />So, it is about the diminishing effects at higher levels of education.<br />On your second point, organisations are still interested in testing intelligence, though the tests usually have other names. Government bodies are usually more evasive (the US military can test intelligence so long as they don't say so too loudly) but private companies test "ability" "readiness" "thinking skills" and so on, avidly.Anonymoushttps://www.blogger.com/profile/09320614837348759094noreply@blogger.comtag:blogger.com,1999:blog-4624586630299165335.post-41115743225966958072015-09-08T23:41:06.561+01:002015-09-08T23:41:06.561+01:00A small point: "Ritchie et al.

" doesn't seem entirely consistent with "Matrix Reasoning and Figure Weights are the measures less influenced by formal education". <br /><br />A second point, and meant seriously not sarcastically: what is the point nowadays of research into measuring IQ? I have the impression that IQ is such an anti-PC concept that many organisations are reluctant to use it - particularly many organisations in the US. Or am I simply wrong in that impression? <br />deariemenoreply@blogger.comtag:blogger.com,1999:blog-4624586630299165335.post-35523932413234237052015-09-08T16:49:19.762+01:002015-09-08T16:49:19.762+01:00Regarding the Spanish Inquisition: https://m.youtu...Regarding the Spanish Inquisition: https://m.youtube.com/watch?v=d3N0uEGVv48<br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-4624586630299165335.post-29557116214731211442015-09-08T15:43:51.905+01:002015-09-08T15:43:51.905+01:00there's a continuum - on one end we can measur...there's a continuum - on one end we can measure many different-ish things in a cursory manner, on the other end we can measure very few things way too many times - no sense in measuring the same thing 10 times:)<br /><br />a composite based on only 2 or 3 subtests may have high reliability - or not - it depends on those pesky subtests (reliability/intercorrelations/& the sample)<br /><br />factors definitely depend upon what tests are in the mix. factor stability of traditional ability tasks doesn't very much unless given to a group without much variability - say to a very low ability (or very young) group - they will have fewer factors. but g is always there:)<br /><br />the WJ-IV replaced many of their WJ-III GIA subtests (relegating old ones to the supplemental bin). some folks question why we were giving them all those years if they didn't work well enough to be included in the new GIA. some call it progress.<br /><br />all IQ tests are works in progress (as is science!) yet marketing departments never want to call them "works in progress" - they want to change them as little as necessary to appear up to date, but not so much they are unrecognizable & hence too much work to (re)learn!<br /><br />marketing would be happy with "now more scores from fewer tests! less work - more scores! buy now!" :)Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-4624586630299165335.post-73794837602521145882015-09-08T15:10:40.876+01:002015-09-08T15:10:40.876+01:00For more on the shenanigans of test publishers, se...For more on the shenanigans of test publishers, see <a href="http://www.ux1.eiu.edu/~cfglc/Adobe%20pdf/Publications-Papers/Canivez%20&%20Watkins%20(in%20press)%20WISC-V%20Review.pdf" rel="nofollow">this thorough review</a> of the WISC-V by Canivez and Watkins.Anonymousnoreply@blogger.com
