will quote page 44:
"[The OECD] way of thinking sees money as bringing dignity, sees children as being of greatly varying abilities and sees its own educational testers as knowing all the correct answers to its battery of questions for which there is clearly no international agreement over the correct answers.
It is not hard to devise a set of questions and a marking scheme that results in those you test appearing to be distributed along a bell curve. BUt to do this you have to construct the world as being like this in your mind. It is not revealed as such by observation."
"What observation reveals is that ever since we have been trying to measure "intelligence" we have found it has been rising dramatically. This means that the average child in 1900 measure by today's standards would appear to be an imbecile, 'mentally retarded' (the term used in the past) , a 'virtual automaton' .When we measure our intelligence in this way it appears so much greater than our parents' that you would think they would have marvelled at how clever their children were (but they didn't)"
He then has an entire section on Graphs that arouse suspicion in which he analyses the methodologies of the OECD exams
"Almost identical curves could be drawn for different countries if human ability were greatly limited, such as those curves shown in Figure 2. This figure is drawn from the key findings of the 2007 OECD report, which includes six graphs. None of those graphs show a single bell curve. Figure 2 reveals how the OECD economists think ability is distributed among its member countries, and in three particular places. It is possible that the OECD economists were themselves reluctant to draw the graph because they knew it would rightly arouse suspicion. However, it is far from easy to guess at the motive. What it is possible, if extremely tedious, to do is to read the technical manual and find hidden, after 144 pages of equations and procedures, the fact that those releasing this data, when calibrating the scores (adjusting the scores before release) ,... "assumed that students have been sampled from a multivariative normal distribution." Given this assumption, almost no matter how the students had 'performed' , the curves in Figure 2 would have been bell-shaped. The data were made to fit the curve."
