One reason that New York Times coverage of testing isn't very good these days (barely over a 4 on a 1 to 9 scale, while I scored about a 7) is because it's generally not assigned to the Science and Medicine staffs, which have a lot of solid veteran reporters. It seems like the beat is usually covered by a combination of Education, National, Opinion, Business, Legal, and Local writers, few of whom know much about this complex subject.
The Local kindergarten IQ test stories are probably consistently the best testing coverage that the NYT does, because subscribers want the straight scoop on how to get their kids into a $40,000 per year kindergarten.
On most else, however, subscribers just seem to want to know what the right kind of people think so that they can think the same thing too. Knowing what you are supposed to think makes conversations go much more smoothly at fundraising receptions for parents of toddlers who got into expensive kindergartens that use the Wechsler IQ test for admissions.
Beyond all that, there's the issue of mastery. Personally, I find cognitive testing to be cognitively challenging to understand. I'm just barely intelligent enough to write about intelligence. It takes a lot of work to move from the point where you have to rely upon fluid intelligence to where you can skate by on crystallized intelligence. It's not surprising that people who drop in on the subject briefly during their quick stint at the Education desk seem particularly baffled.
