IQ predicted by parents white collar or blue collar job

[NorhamGardens]

I had to have one of mine assessed by an educational psychologist.

In passing we discussed DC's school, he used to work directly for the school.

He said with absolute conviction that a blue collar parent/s were likely to have a child with a much lower IQ and a white collar parent/s a child with a much higher IQ.

It made me wonder how many other professionals in similar fields have similar ideas?

I was very surprised. Surely this is classist and hasn't the 'thinking' behind IQ evolved anyway?

I once had a very strange conversation with someone I worked for. He was a director of one of the largest american investment banks. He told me that it was highly likely that if jobs were offered on IQ test alone, I would be sat behind his desk.

The basis for this, he had decided that Jewish people were more intelligent because our ancestors were literate for hundred of years and as a culture we were interested in education Many Jews lived in terrible poverty, some in the pale of settlement, some in ghettos, many had no access to education for many generations. Sometimes people overcome their situation but I don't think intelligence is the key factor. Culture within the home, the mothers interest in her children's education and the child having been made aware of the short comings of his situation.

I'm not sure what your point is Edam? Regression to the mean is well established for height, obviously, and to the (limited) extent to which IQ is hereditary then it should be a factor for that too.
But tall people still tend to have above average height children and by analogy academically succesful people would have children who score above average in IQ test even if IQ were a pure brainpower test. It isn't, obviously, but regression to the mean isn't relevant to the argument.
A little background reading does provide a tiny spark of optimism amongst the doom - IQ results have been rising significantly faster at the lower end than the higher, even in very young children, worldwide - possibly as a result of improved nutrition in gestation and early infancy, or, less encouragingly, as a result of an environment more attuned to the sort of thinking that produces a good result in IQ tests.

I have become very interested in the whole subject of IQ and IQ testing since my own ds has been tested several times and scores extremely high.

I did read somewhere, whilst looking into all this, that the single most important factor in determining the IQ of a child is the level of the mother's education.

Agree with the point made about regression to the mean. Two hyper clever people will probably have a child that is less clever than they are.

I came across a list once that listed average IQs for various jobs.

Some of the most modern IQ tests do test fluid intelligence (innate) more than crystallised intelligence (learned) Each individual subtest is classified as either testing fluid or crystallised intelligence.

When ds was tested the fluid tests were the ones that I took most notice of as these were the ones that he was born with and didn't learn.

The whole subject of IQ testing is controversial and does cause dispute. However I found it to be very useful in determining what was going on with my ds and how he compared to his peers as he was having significant problems with his education.
