IQ and the medical model basically save my life.
I am very seriously dyslexic.
Having a metric like IQ that can be broken down internally, meant that educational psychologists where able to demonstrate that I was not just dumb.
Being able to say look there very significant difference between his actual IQ and the IQ he would have if his reading and writing skills sat at the same level as the rest of the elements that make up IQ.
That evidence forced the local education authority to pay for special needs schooling, which is basically the only reason we can have this little chat.
IQ is a useful tool.
Well, again, that sort of testing is not what Gould was arguing against. Gould was very much in favour of educators identifying students who need help, and getting them the help they need. What The Mismeasure of Man
argues against is the idea that a person's intellectual worth can be measured with a single number (called "I.Q.", "General Intelligence" & "G" by various people) and that that number is inherent
and not affected by environment or educational circumstances. This
concept of intelligence has been, and continues to be, used to dismiss individuals and groups of people as inherently "unintelligent" and undeserving of the basic opportunities to succeed that others are granted without question.
Here's another example of the inequities that this concept of "intelligence" has been used to justify: For decades in Britain, children were tested at the age of 11 for "General Intelligence" and on the results of those tests they were sent on to either grammar school (to prepare them for a university), technical school (to learn a trade) or modern school (to prepare for a life in the service industry). The grammar schools received more funding per student than the other schools, and their students typically went on the university and much more prestigious, high-paying jobs. Trade & modern school students weren't offered the classes required for university entrance, and had to work harder than grammar school students to get into university. In addition, when the baby boom generation began to enter secondary schools, the requirements to enter grammar school were raised in order to keep budgets down, increasing the inequity of the British education system.
Now, under that sort of regime, how do you think you would have fared? Do you think that you would have gotten the help you needed? or do you think you would have been told that you were "just dumb" and sent on to a life in the trades or service industry?
